What’s the maximum video size / resolution that CasparCG can play?
CasparCG supports resolutions from 1×1 pixels to HDTV resolutions such as 1280×720 and 1920×1080 and up to 2K and 4K. It was primarily designed for PAL use, however. The theoretical limit for Flash content (including bitmaps and similar media) played by the “Flash Producer” is a total of 16,769,025 pixels with a maximum width or height of 8191 pixels. The largest square media that can be used is therefore 4095×4095 pixels. Don’t expect miracles when it comes to playing back content of these sizes, though.
