Guest column by Prashant Yashpal from Activ8Media in India....
Kitty Su is a popular nightclub in New Delhi, India. For its first anniversary on 18th August, 2012, they wanted to add a visual experience to their club. They called upon their trusted partner Most Technical India, who in turn called us, Activ8Media
, to create a video/projection area for the club.
The idea was to create a unique visual experience, around the DJ console. At first we thought about putting regular lens projectors to cover the area, but shadows and projection interference is a big problem in night clubs. People standing close to the DJ console always block projection video and the light disturbs the DJ/VJ/Crew. Installing LED panels would not look good at close range, plus the club wanted to maintain its interior design and look.
So we decided to change the cube fabric from the dark brown which adorns the clubs walls to off-white, to give use better color depth.
We finally decided on taking the risk and using Panasonic mirror projectors, generally used for classroom/business environment. The Panasonic PT-CW230 allowed us to mount the projectors at 10 inches from the wall. The challenge was with ultra-short-throw projectors we needed 7 (!) of them to cover the entire wall.
After lots of research and experiments we decided to go with our favorite VJ software Resolume Arena 4, as expected it did the job beautifully. Using a total of 8 outputs from our beastly PC, 7 DVI’s to projectors and 1 for monitor. Giving an output of 4200px X 550px, we fed each projector with 600px X 550px. We know this is not much but the height and width required from each projector didn't require more resolution.
Arena’s advanced output helped tremendously, we could easily slice our input composition inputs into 7 and feed them to individual outputs, then mapping and edge blending each projector carefully. It was like working in After Effects and didn’t take much time at all, compared to a lot of heavy weight media servers.
Also one great thing after slicing and matching inputs to outputs and saving the advanced output settings, we could easily resize our composition without adversely affecting our real output! All mapping and edge blending remained same as before. This was a life saver! As we were trying to figure out the best output resolution once the projectors we installed and on site.
*OH we only had 2 days for setup i.e. we got the console setup and wiring ready on the 16th and show was on the 18th!
All in all, it was a great experience, the client was thrilled! We had used classroom projectors in a club for the first time, the visual effect was simply stunning, without shadows and strange visuals on the crew
. Something we had not done before, Arena proved to be a champion!
