[MEncoder-users] Need help reducing 720p 60fps to 30fps or 24fps

[Laine Lee]

This was as close as I could get with your sample. Is there a chance that
the recording might contain dropped frames? The parts of my results that
seemed most jerky appeared so sporadically.

mencoder [debug-sample.mpg] -oac lavc -ovc lavc -of mpeg -vf
