Video compression in Keynote and VLC

[neutrino23]

I just recorded a video in Keynote and exported it as a movie (H.264). I then ran that through VLC and exported it as H.264. The file size was about 15x smaller. Comparing the two, the more compressed version looks a little washed out (no surprise).

Neither of these apps seems to provide a slider for the level of compression to be applied. Am I missing something? These will be training videos for our software product so a moderate amount of loss in the video is tolerable.

Can someone point me toward a reference that discusses this topic (level of compression) and maybe has some tips for ways to do simple compression?

Thanks.

From the iMovie output use handbrake. The defaults work well, but there are sliders.

Thanks, I’ll give it a try.

Does anyone have experience with Compressor?

Yes. Great way to get exactly what you want, with a somewhat steep learning curve.

HB is free (and relies on vlc for the ripping - you already have) and is imho a great app for this sort of thing.
