[Feature Request] Add option for screen capture in 30fps .mov format, and smaller resolution (for GitHub readme's)

[shinra-electric]

I'm loving this app, and I'm using it for taking video captures of apps that I'm posting in my portfolio on Github. (There are a lot of your tutorial apps there...).

I used to post gifs of the apps until I found out that .mov files tend to be smaller in size, and were supported in GitHub. Mp4's don't seem to work for me.

So what I'm doing now is:

1 - Control Room to capture the video to mp4
2 - Handbrake to convert to 30fps mp4 (H.264) and remove audio
3 - Quicktime to export as 480p mov.

The resulting mov file can be posted in GitHub readme's and is very small in size (a couple of MB depending on the length of the video and screen size. watchOS videos can be a few hundred KB).

It would be great if Control Room had a "Github" option to save video with these specs.

Note* I've been using H.264. I'm not sure if Github supports H.265 .mov files yet, which would probably be even smaller. I'll give it a try and comment later if it does.
