Video encoding for YouTube with fast motion
on Feb 26, 2014 at 2:06:21 pm

I have a fast paced video with quick 2 and 3 frame cuts. I was wondering what h.264 settings would give the best playback quality on YouTube? Currently outputting h.264 from Apple Compressor using the 720p preset. How might I tweak the compressor settings to get best quality? I know that Youtube re-compresses the video, so with this limitation, what settings are best?

Original media 1080i/24p (23.976) DVCPRO from Panasonic HPX170

I usually turn on Frame Controls and choose the highest quality in relevant fields. In your case de-interlacing and possibly resizing. I also push the data rate as high as 30mbps for HD.

So your sequence is 1080p24 DVCPROHD?

Export a self-contained quicktime movie. I'm not familiar with the new layout of Compressor 4 but in the old version:

Bring that into Compressor, search for the QuickTime H.264 option and drag that onto your video. Then in the Encoder tab, click Settings next to Video and adjust the quality from Best to High (best will give you a crazy high data rate). Turn KeyFrames to Automatic and compress your video.

What about the H.264 mode: Baseline, Main, High? and the entropy mode: CAVLC, CABAC? Keyframes? Single-Pass, Multi-Pass? I've never seen a good explanation of these and their advantages/disadvantages, or why one would want to change these settings.

Check this webinar out by Jan Ozer, he's a well known compressionist. You just have to register (it's free) to get access to the archived video, or just read the transcript.
