Quicktime Screen Recording Lower Frame Rate

Question

I'm on mac, I'd like to screen record. But I want it to record a frame every second or so, or every minute or so (as opposed to 30fps). So when someone plays the video it will look sped up.

Is there a way to do this in quicktime (preferably) and if not, is there an app or a command line tool I can use to adjust the framerate after recording?

Solution

Found it. Although it doesn't use Quicktime it seems to be a good way to do it.

Just take an image every X seconds, and then after you have hundreds (or thousands) of images combine them into a movie.

An example that does this: https://github.com/potomak/screencapture

Why don't you just record the video at 30 FPS then modify the video to increase its playback after the fact?

@Ramhound If you had read to the end of his question, you would have realized he had thought of that and was asking for help on that aspect as well.

I actually did read the question. I took his question as wanting to modify the recording, so it would record at 1 FPS, instead of 30 FPS.

Also another problem with recording the video at 30fps or whatever it records is that after 30 minutes it already takes 1gb. :/ If it were lower framerate it wouldn't take as much.
