Slow motion

how can I put my pitching videos in slow motion(preferably) or frames?

It depends on the format of the video. On YouTube, you can’t. That’s the frustrating part of it. mpg, mpeg, gif, avi all are great because they can be opened in QuickTime which allows stepping through them frame by frame by using the right and left arrow keys.

so there is now way to put a pitching video on here in slow motion?
