Hello Jonas,
I will give the content specs of the most recent project:
The biggest content clips were 2880px x 720px. We used a number of 1280px x 720px as well. The compressions is always MPEG-1, bitrate 10000 b/sec, framerate 30.
Our workflow involves a fair amount of compositing within Watchout for our shows. We also use a lot of PNG files with transparency.
We use TvOne DVI extenders (1T-CT-520 series).
Thanks,
Lalindra
