I believe it is mov instead of mp4. mp4 would be great since it takes much much less space.

MOV and MP4 are container formats, so MOV can be smaller than MP4 depending on the video formats used.

Sure, but there's no option to control which format it creates the capture in. Besides I end up ffmpeg converting it to mp4 and get a video about 10x smaller.
