    written by guest blogger Frank Danko

    Editor’s note: Mr. Danko was recently at Chauvet HQ for a training session. While here, he shared a quick, yet passionate speech about the benefits of USITT and theater education in general with the group. We were so taken with it that we asked him to write a post as a guest blogger. And here it is…in two parts. Enjoy!

    I am not an educator in the formal sense of the word, so please forgive my grammar. However, what I do is certainly educational for those I am fortunate enough to meet in my travels. As the theatrical lighting representative at BMG Hudson Sales & Marketing (NY/NJ), I have the great pleasure to educate customers and colleagues alike on the quality products manufactured by CHAUVET Professional.  My lessons certainly do not Desks in an Empty Classroomtake place in a classroom, my lessons come alive in offices, theatres, venues and the occasional bar. As lighting professionals, we must be in constant pursuit of knowledge to grow with our industry and further the development of those around us.

    Never stop learning.
    Many of us have not been in the classroom setting in quite some time, but we remain eager to learn in our professional lives. Through educational organizations, such as the United States Institute for Theatre Technology (USITT), there are wonderful programs for aspiring technicians and seasoned veterans alike. Since 1960, USITT has been dedicated to the growth of our industry and the education of our future technicians. Its commitment to our future has developed new technology allowing our industry to adapt in this ever-changing world. I sincerely hope you were able to attend the recent USITT held in Milwaukee, Wis. I was not able to attend, but it did remind me of my personal journey in lighting; one that I’m proud to share with you in this blog post.

    But what do you do?
    A few years ago, while hosting a workshop on lighting design for high school students, I was asked, “what does a theatrical technician do?” I have spent the majority of my career working as a technician, but I never asked myself the WHAT question. I thought it was obvious to anyone who has ever seen a show, and so my answer was “We do everything!” The student looked at me sideways and under her breath I could hear her say, “That didn’t answer the question.” In an effort to clarify, I began to list the responsibilities of technicians: we hang, focus and program lights, run cables, call shows, move sets, set microphones, push boxes, hand off props and even dress the talent. I could see she was beginning to understand and like a batten falling from overhead; it suddenly hit me that the WHAT didn’t matter. I never cared what the task was, I was just happy to be a part of something larger than me.

    Empty TheaterThe great white dream.
    As a young teenager, much like the students who attended my workshop, I was eager to learn. At the time, I never thought of pursuing a career in technical theatre, in fact, I was destined to be on Broadway. Growing up 20 minutes outside of NYC, I was fortunate to attend shows from a young age; naturally I wanted to be on stage. It wasn’t until my high school performing arts director asked me to come to “Stage Crew” that my perspective changed. I walked in the auditorium and there were all of these young people just like me, playing with power tools, painting sets, focusing lights and turning microphones on and off. This was a whole different world and I must admit, it was a bit overwhelming at first. It was quickly made very clear by the senior crew chief—this wasn’t rehearsal, this was work. So I began to work, first by helping push the Genie lift around for one of the upper classmen focusing front of house. I asked questions, I listened and followed directions to the best of my ability. At the end of the day my teacher approached me and asked, “Coming back next week?”  To which I replied, “Absolutely!”catwalk

    Soaking up knowledge.
    In my junior year, our school bought a new computerized lighting console. It didn’t operate on AMX like our original board, it was a technology called DMX 512-A, one that I was not familiar with. Like any good techie, I started to research this new console and the DMX protocol and discovered USITT. It is responsible for DMX512-A becoming the industry standard in entertainment lighting. While researching USITT, my teacher also informed me of several great organizations like the NYS Theatre Education Association (NYSTEA), Educational Theatre Association (EdTA) and the International Thespian Society. These organizations were working to make theatre education a priority. This seemed important to me, very important. I became involved with NYSTEA because of my teachers involvement and I attended my first event, right in my own school. There were over 100 students from my region who had the same interests as me and I spent the day taking workshops and soaking up knowledge.

    Sharing newfound knowledge.
    My teacher informed me that USITT would be hosting a conference in Pittsburgh, Pa., later in the year. I asked my parents if I could attend, they were reluctant but took a friend from stage crew and myself to the event. I saw all the exhibits, played with equipment and even programmed my first intelligent fixture. I walked the show floor for hours, met industry professionals and listened intently to everyone I encountered. It was an amazing experience and I couldn’t wait to tell my teacher and classmates about it.

    The journey continues. Click here to read part two.

    Tech Talk: 16-Bit Dimming for LEDs

    Written by on . Posted in Uncategorized.

    Written by Mike Graham, product manager for CHAUVET Professional.

    The latest push in the world of LED lighting has been control of said LEDs. Dimming has been a problem since the beginning of LEDs in the entertainment industry and has effectively made it so that it is unacceptable to many lighting designers to use LEDs for anything except scenic elements and highlighting. For some reason, having a ‘steppy’ low end that looks like a flat tire sounds is a bad thing.

    Chauvet has done some amazing things over the past few years with regards to this problem. We released fixtures with built-in dimming profiles a few years ago in the COLORado, COLORdash and Q-Series of products to help with the visual version of ‘thump thump thump,’ and that helped a lot. Doing a fade from 50% to 0 over a few seconds now looked a lot smoother. The bar has been raised again.

    Several manufactures (including Chauvet) are introducing 16-bit LED dimming, which virtually eliminates any remnants of the dreaded ‘steppiness’ that has plagued the industry for years. Chauvet has already released several products with 16-bit dimming included, such as the Ovation series or COLORado 4 IP to name a few.

    Microsoft Word - Document2Sixteen-bit dimming offers the user the ability to easily control LED dimming just like you would control fine pan and fine tilt. As always, there are 255 steps of control in 8 bit (standard) dimming control. With the fine control offered in 16-bit mode, there are 255 additional steps between each step of the standard 8-bit dimmer channel. This additional level of control allows the fixture to act much more fluid in dimming, especially at the low end where it has always been problematic. In the DMX personality, the channels would be set up like in the image at right, in the case of the COLORado 4 IP.

     

    Microsoft Word - Document2

    If the profile is set up correctly on your console, all you will see is something similar to the image on the left. This is because the person who built the profile has already incorporated the normal operation with the fine control, in the same way that fine pan and fine tilt are included in the parameters for pan and tilt in most personalities. If you could see the values of the 16-bit channel move during a cross fade, you would see the numbers whip from 0 to 255 and back again faster than you could possibly read them. However, if you are using a fader controller, you will still have to use the fine channels for tweaking your color output and is most useful in the very low end of control. What I would suggest is to have the main control at your desired level of output and the fine control at full. I would suggest dragging the main level to zero during dimming and drag the fine control to zero following the main control. This will give you the best control of the low end in a manual situation.

    As a final tip, in any 16-bit control situation, it is important to turn off any dim setting or dim curve settings. They should be both turned off so that there is no conflict between the controller and the fixture. Keep in mind, those settings were designed to help the fixtures compensate for 8-bit control. As long as you are using a 16-bit personality, your fixture does not need any help on low end dimming.

    —Mike Graham comfortable in the spotlight.

    Written by Mike Graham, product manager for CHAUVET Professional.

    Over the past few years, we have covered a really wide range of topics. I don’t think we have ever covered video lighting.  So, with no further ado, we proudly present, [insert drum roll here] … lighting for video.

    There are a few commonalities in how we approach this subject. It’s all about angles and elevation. Without even talking about fixtures, let’s approach positioning first.

    I. Know your angle: 

    There are three major types of lighting in video:
    • Key lighting — In an ideal setting, I would suggest getting your key lights (front lights that cover the subject being lit) at about a 20-degree angle above the subject and about 45 degrees off to each side of the subject. This will minimize the shadows on the front of your subject. Key lighting is the business side of video lighting; it makes up for the brightest lights in the room and are only there to highlight the subject.

    • Fill lighting — For fill lights, (side and back light that is used) angle higher (45 degrees plus to the top and 20 to 30 degrees to each side.) Fill light is less intense than key and often will have color in it. Fill light is used to give the subject depth and is the more artistic portion of video lighting.

    • Scenic lighting — is what is used to light up the set (same as in theatrical lighting). Scenic lighting is totally up to you, but don’t make it too bright as you want to make sure you don’t have to bring up your key light so much that your subject is burning up, or more importantly, the video director is not telling you to dim stuff down because all he can see is white glow on his monitor.

    II. First steps for your design:

    This is where I would start a design: much like in theatre lighting, you can divide up your stage area where the video is being shot into acting areas, and then create your lighting plot accordingly. Again, like theatrical lighting, video lighting is all about building a lighting position and repeat. This is why a TV studio looks like a lighting showroom. Each person who is sitting on a news set has his/her own key and fill lighting.

    • Tips for practical applications — When it comes to the more practical applications like corporate meetings, the common setup is to have a speaker in the middle of a raised stage between two projection screens. In some cases, there is a projection screen in the middle of the stage, as well. In these cases, you have a few obstacles in the way of your lightshow. You have to keep all of your key and fill lighting off of the screens and on the presenter, which shouldn’t pose a problem as long as the presenters stay at a podium in the center of the stage. A little front light, a little side light, a little back light and away we go. However, what if you have a “wandering target”?  Let’s say that you have someone who likes to walk and talk at the same time. How do we light that and keep our projection screens clear of any ambient light? At this point, sidelight becomes more important. We will have to raise our front light up to about a 35-40-degree angle and use more side light. Fresnel-style fixtures with barn doors are great for this application. You can cut off the light from the upstage side and flood out the front. Your sidelight will act as your fill in this case and should keep your presenter in good light no matter where he/she wanders. With regards to your front light, you just need more of it. I would suggest using ellipsoidal fixtures for this application. The beam is very directional and you can shutter-cut the upstage side to keep the light off of the screens. When you have your front lights all in position, you may want to throw them slightly out of focus so that the edges of each fixture even out with each other and prevent hotspots. To be honest, it is almost exactly how you would light a dance recital.

    III. Know how to color:
    So now we have a little information about positioning of lights and some suggestions about what kind of lights to use. What about color? What are my best bets for making all of this blend together and come out looking professional? Front light, as we have discussed is all about the cameras getting what it needs. Most cameras like warm light (3,100K-4,000K) depending on the camera. CHAUVET Professional Ovation E-190WW and Ovation F-165WW offer a 3,150K light source and it is possible to cool them down a little if needed with a correction gel. Another source of white light is the CHAUVET Professional COLORado Zoom WW Tour. This fixture has tunable white colors that can be adjusted anywhere inside of the typical range of warm white. It can also be zoomed from a tight to wide angle to assist with coverage if needed. For side, top, and backlight, it is very common to use more color in them.

    CHAUVET Professional Ovation C-1280FC

    CHAUVET Professional Ovation C-1280FC

    Again side, top, and backlight are all types of fill light. The main purpose of these light sources is to add definition to the subject that is being lit.  Since you are blasting them with front light, your subject will be flattened out. The fill light needs to be just bright enough to add some definition to the subject that you are lighting. Personally, I like to keep it natural. A combination of warm ambers and cool sky colors is a really good way to make sure that your subject stands out; just keep it diffused and not too bright — just enough light to make your subject look natural. Scenic lighting is just that. It makes the scenery look better than it did when it came off the truck. Simple uplighting and some strategically placed gobos will  do the trick most of the time. It is amazing what you can do with a six-pack of WELL 2.0 battery-operated wash lights and two Ovation E-190WW fixtures with break up gobos installed.

    IV. Remember your people:
    Now that we have our lights positioned, focused and colored, we have to work more with the camera people. The first thing that they would probably do after they set up is a white balance on their cameras. This is the time when they will ask you to turn your front lights up to full. They will put a white sheet or something of that nature in the middle of the stage and adjust their cameras to the light that is reflecting off of the white material. This sets the camera iris and color sensors so that when they shoot, the subject does not get blown out and look like a ghost onstage. This is particularly important for live applications where there is no way to correct the images in postproduction.

    By now you should be fairly set to run your show. Keep in mind that it will look too bright onstage for your taste in most cases. However, for the people who are shooting video, this is just perfect!

     

    Tech Talk: 5 Tips on On-Site Problem Solving

    Written by on . Posted in Uncategorized.

    Mike Graham comfortable in the spotlight.

    Written by Mike Graham, product manager for CHAUVET Professional

    One of my favorite lines from “The Breakfast Club” is “It’s an imperfect world. Screws fall out all the time”. Truer words have never been spoken. If you ask any seasoned show technician, they will tell you that they remember more shows that went wrong than went right. The trick is to know how to react when it all goes wrong.

    This past week during the Super Bowl, the lights went out. When I saw that, my first thought was, “I’m glad I’m not there working.” My second thought was, “How will they get the lights back on and keep everyone in the stands safe while doing so?” From what I could tell on TV, it looked like the security team and the engineers at the stadium had a good action plan to cover the unthinkable happening. That could have been a complete disaster, but luckily for everyone at the stadium, it was fixed and the game went on.

    Here are a few tips on how to keep show problems from becoming showstoppers:

    1. Know your gear – Knowing the ins and outs of your gear will make it a lot easier to get yourself out of trouble. If you know your gear really well, you will be comfortable enough to be able to punt if you have to.

    2. Have backup of important control items – If your budget allows, it is a great idea to have a backup controller on hand if the one that you are running your show from dies. Have at least one extra DMX line from the controller to your dimmers or opto-splitters. In case one of your DMX universes goes down, you will be able to change the cable. With regards to Art-Net or video control, I highly recommend having a backup Ethernet cable in your snake so that in the unlikely event of your main cable getting damaged, you have your spare ready to go.

    3. Practice punting – During rehearsal, I strongly suggest practicing switching out gear, in order to be prepared if something fails. If you don’t have time during rehearsal, at least talk to your team about what to do if the unthinkable happens. Have a clear and concise method of communicating problems and what to do about fixing it. Make sure that your talent is also aware of your backup plans.

    4. Keep a list of cell numbers handy of your crew – If for some reason, your headset communication dies, cellphones are a great backup. At least good enough to let people know that there is a problem and that you have lost your headsets. I also recommend that you keep their numbers written down and not just in your contact list on your phone. That way if you lose your phone, you are covered still.

    5. Keep calm and rock on – At the end of it all, the most important thing is to make sure that everyone who came to the show leaves safely. We have a responsibility to make sure that happens.  Don’t sweat blowing a cue.  Everyone does it.  Don’t even sweat losing control of your lights, just fix it.  Get the house lights up, turn on work lights, but make sure that there is light.  As long as people can see, even a little, they will stay calm and orderly.

    Tech Talk: How Many Languages Do You Speak?

    Written by on . Posted in Uncategorized.

    Mike Graham, comfortable in the spotlight.

    Written by Mike Graham, product manager for CHAUVET Professional

    As a protocol droid, C3P0 is fluent in over 6 million forms of communication. As a lighting industry professional, I feel like we need to be competitive with that number. I’m not saying that we need to be able to speak and understand so many languages, but we should know how to speak to our ever-expanding range of gear.

    The beginning of DMX

    So, let’s back up a bit. DMX was standardized in 1986. That is to say that USITT required all of the lighting and controller manufacturers to speak the same language of control. All was good in the world (for the most part) as all lighting controllers spoke with all dimmers and lights. This still remains true, as DMX is still the standard. And as a whole, I think that we all speak DMX relatively well. However, it has gotten a lot more complex for the lighting industry professional to just speak DMX, and on just one type of controller.

    Disclaimer: If you are lucky enough to be on a sit-down gig and only have to use the (insert console of choice here) to operate the same rig every night, then you can stop reading now. However, if you are planning on doing anything different in your career, then keep reading.

    Accessible software

    At this past LDI, I saw something that I never thought I would see. I saw not one, but at least three of the major controller manufacturers release a widget that would allow any user to download some software to their computer for less than $100.00, and to be able to use a full universe of DMX for their extremely professional PC version of the full-size controller. This tells me that the controller manufacturers are coming off the hilltops and trying to win over the masses of users. This also tells me that as one of the mass, I had better learn all of these platforms and speak the programming language well enough so that when I show up to a job, I can easily work any one of these platforms.

    Pixel-mapping Nexus 4×4 works with DMX, Art-Net and Kling-Net protocols.

    Along with the controllers becoming a little more cost conscious, I have also seen a rise in fixtures that will work directly with Art-Net. Art-Net is essentially the TCP/IP version of DMX. This protocol allows the control platform to output on a total number of DMX universes only limited by the processing power of the controller itself rather than the amount of DMX outputs that are present on the back of the board itself. CHAUVET Professional is releasing its first fixture that will allow direct input of Art-Net: Nexus 4×4. By allowing direct input of Art-Net, building large matrixes of color-changing array fixtures like the Nexus 4×4 becomes much easier. This is because not only do you assign the DMX address to a fixture, but you also assign the universe number. This means that Fixture A can be Universe #3, DMX address #38, and Fixture B right next to it can be Universe #15, DMX address #54, and the CAT5 cable can go directly from Fixture A to Fixture B. There is more to it than that, but again, it is another language that we need to be able to speak.

    ÉPIX Series of pixel-mapping fixtures speaks Kling-Net.

    Past DMX, we have video languages. At Chauvet we have two distinct languages for video: LINSN and Kling-Net. LINSN is a language that is used to communicate between (in our case), the MVP Media System, the MVP Driver, and the video panels themselves. We use this language as it is designed to transmit huge amounts of information over a CAT5 cable to the video panels themselves. In video control, this is the first part of the communication to make sure that the panels are properly configured. Next is configuring the media server to play back your video content how and when you want it to play. There are a few options for this; do you want to use time code? Then SMPTE or MIDI is the key, if you want to have direct control from your lighting desk, that is an option as well as you can always use Art-Net and in some cases, straight DMX for that purpose. Again, that is a minimum of understanding at least four different languages right there.

    Our second video-based language at Chauvet is Kling-Net. Kling-Net allows matrix configuration of specific Kling-Net enabled devices, such as the ÉPIX Series and the Nexus 4×4 with ArKaos MediaMaster and MediaMaster Express software. Kling-Net is another TCP/IP based software that unlike Art-Net, which uses a static IP address, uses a router to assign an IP address to each fixture. Once the fixtures are addressed and configured in the Kling-Net mapper, you can switch the output back to MediaMaster and have content playing back in no time. Again, a few more languages to speak.

    As I have been saying all along over the past several years of Tech Talk, education outside of your comfort zone is really important. I have brought up eight different protocols and languages here, and I didn’t even touch on RDM or ACN, but this barely scratches the surface. The point is that it is critical, now more than ever to be reading, downloading, and playing with different kinds of controllers and protocols every chance you get. The lighting world is no longer just lights and hasn’t been for a long time. And I can guarantee you that it is just going to get more and more complex.

    Tech Talk: ‘Hey, That’s My Wrench in Your Bag!’

    Written by on . Posted in Uncategorized.

    Mike Graham, comfortable in the spotlight.

    Written by Mike Graham, product manager for CHAUVET Professional

    I can’t tell you how many times I’ve said that over the past 20 years. Too many times to count, that’s for sure. However, there are some simple and easy ways to make sure that the tools and gear you showed up with at the job or show site actually go home with you.

    Nothing is more frustrating than seeing that shiny new Crescent wrench you just laid out $10 for in someone else’s tool bag. OK, there are more frustrating things, but you get the point. But, how could I have stopped it? Read on and follow my tips, all gathered from experience:

    I. How to protect your own tools. 

    • Much like a wolf, mark your territory. Copying the wolf exactly may not be a good idea, as your tool bag will start to smell. It’s the same concept though: mark your tools with something distinctive. You can engrave them with your name, or put a ring of colored tape on them, or spray paint them in some color (like hot pink) that you know is your mark. This will slow the other wolves from long-term borrowing your precious matt knife.

    • Take out of the bag only the tools you use. Since on the show and job site, there are some tools that should never leave your box, and some that are in your hands all of the time, it is important to keep the ones in your box away from the eyes of others and only taken out when needed. This would include any tool that requires a battery for operation. Typically, those are much more expensive to replace. As for the stuff that goes in your pockets, like a C-wrench, #2 Philips head, snips, and a matt knife, you have to know where they are. Keep them in your pocket and make sure that they are clearly marked as yours. I picked up a ratcheting C-wrench about a year ago. For me, it’s great. I finally got used to working with it at LDI 2012. Someone who shall rename nameless decided to grab it from where I was working to “try it out” on the last show. Since it is marked with a particular string with a particular knot, it was easy for me to spot out and ask for my wrench back. Years ago, my best friend went out and picked up a PowerPuff Girls lunch bag that he used for his tools. I must have laughed at him for months, but he could have put a hundred dollars in that bag and no one would have touched it. Moral of the story, be the wolf.

    II. Tips on handling equipment from rental houses. 

    Years ago, when I was tending bar, all of the bartenders on the avenue would get together once a month to share war stories and exchange glassware. We did this because throughout the month, without fail, we would have everyone else’s shot glasses but our own. That works fine for a group of friendly bartenders, not so hot for very competitive rental houses.

    If you are in a position where you are going to have to use multiple vendors to cover your show needs (commonly known as re-renting) you know that you had better get them their gear back to the last truss bolt. Sometimes that can be tricky, especially if you are using multiple vendors for the same gear, which is always a nightmare scenario during load out. Most times, rental companies label their gear clearly with a sticker that has their name on it. They may also use a distinctive color code. For example, Christie Lites uses purple 3-pin DMX cable and green 5-pin data cable. Now, more and more companies are also including bar codes to make inventory faster. They know that if the barcode does not work, it’s not their gear. If for some reason, company A and company B have decided not to mark their gear, then it is up to you to do so to avoid the nastygram that will follow their gear count at the shop. This is where you get to find out how much they paid for an item three years ago when it was brand new as you are having to buy them a new one. There are ways to keep this from happening:

    • Use multicolored electrical tape. The easiest way is to use multicolored electrical tape. (you should always have at least two other colors besides black electrical tape in your box). Use one color for company A and another for company B.

    • The other way is to try to segregate gear in specific locations, which is fine if you are working alone, but is not at all an option when working with others. When you re-box their stuff, make sure that the gear list matches; especially on the items that had to be re-rented. This will save you a major headache at the end. If for any reason your rental company did not send a complete packing list with the exact count of cables, call them and demand one. Without that, you are going to be in deep wolf stuff when you are trying to get the right gear back to the right location at the end.

    Our team needed lots of tools to build this booth at LDI 2012…

    At the end of the day, producing a show is expensive for everyone. On a given show, there are expenses for flights, hotels, trucking, labor, repairs, gear rentals and incidentals. You can’t charge the client for the wrench we lost or the gear that is missing at the end of the show. You have to eat those costs. Those costs directly impact your bottom line for the show and can kill the profit margins. It might not seem like much at the time, but even a good matt knife is still $10. Putting company A’s gear back in company B’s box can be even more costly.

    Dealer Trip to Mexico: Merida, Cancun and Playa del Carmen

    Our own Business Development Manager for Latin America Paula Ortiz traveled to Mexico, in the towns of Merida, Cancun and Playa del Carmen to train general managers, sales managers and salespersons of the Electronica Gonzalez retail stores, a customer of Novelties, our distributor from Mexico. Paula presented new products from CHAUVET Professional, CHAUVET DJ and TRUSST lines, shared information on LED and DMX technology and more. Here are some pics:

    Since video walls have become so desirable for large and medium shows, in my previous blog post, which you can read here, I explained why it is important to know when and how you should create video content. I focused on defining the resolution, the pixel pitch, and how these relate to video. Now, it is time to understand the application and the streamline process. Read on:

    Application:
    When selecting the design for the show, it is important to understand the desired outcome. If the intension of a video wall is to have live video (IMAG) played back on them, then you need to know the minimum viewing distance of the stage and also be sure to select an appropriate pixel pitch for this distance. In situations where you intend you play back motion graphics, the pixel pitch can be as low as 50mm, while still being effective. However, it is often good practice to use the following guideline when selecting video panels for an event where you intent to play back live camera/recorded footage.

    Minimum viewing distance:
    You should convert the pixel pitch to meters, and this is the closest that your audience should be at any time in order to comprehend what the video wall is playing back. For example, 12.5mm pixel pitch panels should only be seen at 12.5 meters, or 40 feet; although with increased distance the quality will look even better. This means that for indoor events in smaller venues, you would likely only want to use panels with pixel pitches of 3mm-12.5mm. And, for outdoor events with longer viewing distances, 12.5mm-40mm panels would be appropriate.

    Indoor/outdoor:
    If you are using the LED video panels outdoor, you should consider safety and strength of the structure you are hanging from. If you are using a temporary truss structure, then you should be concerned about the wind blowing over a solid wall. Therefore, the following words should be included in the product description: transparent, blow-through, and sometimes curtain (not used for flexible panels, but rather panels made of strips). This allows the wind to pass through the gaps in the panels, rather than blowing them over. This also is something that you should consider when selecting your pixel pitch, because larger pixel pitches provide greater transparency. Something else you should consider is the local weather. If you are using the video wall in an area that has frequent rainstorms, you should make sure that the panels have some degree of ingress protection (IP rating of 50 or higher). This does not need to protect against permanent outdoor installation. But, it should be sufficient for unexpected rainstorms.

    How to streamline the process?
    Keep in mind that many video playback software have the ability to grab certain portions of a single video file and send them to individual sections of your video wall. One of these is ArKaos MediaMaster Express. If you are using the Express version of the software, then you have the “cropping” tool. This is invaluable, as it simplifies the preproduction of your shows, and allows you to do most of your conversions to accommodate different pixel pitch panels in the same show, playing back the same content. With this tool, you no longer have to render custom video files 24-48 hours before the show time. Keep in mind that when you are using this technique, you should not apply any masks to the video content, if rendering it.

    This miniseries on how to create video content should give you enough info to start rolling, but remember you have to conduct research on your own, as well, in order to keep up with the new technologies. Don’t be afraid to invest hours of practice and don’t forget to have fun!
