com.apple.screencapture Video Format

• I made sure this feature is not in the commands list
• I searched and didn't find this feature request in the listed issues

I discovered the screencapture CLI for screenshots and screen recordings used by the screenshot UI has a hidden option -F for setting the video format. It's currently limited to "avc1" and "jpeg" but may be worth looking at in the future if they add additional formats. I haven't found a corresponding defaults key for this option (guesses format and videoFormat don't work).

Terminal Output:

user@Mac Desktop % screencapture -Ftest -v -V1 test
screencapture: Invalid video format type
	available types: ["avc1", "jpeg"]

Tested on macOS 15.1.1
