Clip and Video Formats

Only clip formats for 1280×720 are supported by the clip player. The clip frame rates that are supported by the clip player depend on the video format that the switcher is operating in.

Note: The clip player does not support clips with a bit rate of 400Mbps or higher. Clips with a higher bit rate than supported are marked with Caution Icon over their thumbnail. Higher bit rate clips can be played, but will be ejected if they threaten system stability.
Note: Other clip and video format combinations may work in some applications, but playout quality cannot be guaranteed.
Note: The clip player does not support playing clips when the switcher is operating in a pSF video format.
