Claude.Rivet Posted March 27, 2012 Report Share Posted March 27, 2012 Hello, I am trying to find a way to genlock Watchout or any equivalent, here is the reason/problem: -Everytime I use Watchout trough a system like Vista Spyder (X20 1608) or Folsom Encore (4VP system, background connections) I have issues with content not syncing from display to display computer, we are talking minute timing differences leading to either a wobble in the blend or a tearing. The problem is very obvious on scaled live video that is passed trough Watchout (being an HDSDI card we do feed it either data content (powerpoint for example), IMAG or HD video playback from an external source. However the problem also is present on any video playback, pre-split or not, going trough a blend. I suspect still images have the same issue but because of lack of motion it doesn't show in an obvious manner. When we look at the Spyder or Encore input for the exact aquired scan rate we realize 1 display could be at 59.9997 rather than 60 and the other 59.9995 for example. What we tried: -using a lot of keyframe in videos, as much as one keyframe per frame, basically compromising compression which is not a main concern to us. -encoding in a lot of format, h.264, wmv, mpeg, motionjpeg... The problem remains or always find it's way back. The issue being the output timing not the video sync. the problem does not exist or is less of an issue when Watchout is used alone and display computers are connected straight in the projectors, however it can still happen. What we haven't tried: -using one multiple output computer rather than several display computer, we will be limited in terms of processing power but we can find workaround to that, maybe it's the only way, maybe it doesn't change a thing -genlocking, which seems the best solution as all component in the system will slave to one clock. I have no clue how I could genlock a watchout display computer however. I can see myself genlocking the video input card as most have genlock inputs but to genlock the entire display computer is not something I tried or even know if it is possible. SO: -Has anyone experienced the issues we are having? -Have you found a solution? Details would be appreciated. -Can Watchout displays be genlocked? How? Sorry about the long post and thanks to those who will answer! regards Quote Link to comment Share on other sites More sharing options...
