current audio/video compression for computer playback
HI:
What’s the current thinking for creating an h.264 file to playback on a Mac or PC? While we follow YouTube’s specs for uploading, many of our clients want to playback their videos off their computer, using the HDMI out to a big screen. What setting/bitrate should I use for highest quality without monster file size, and what should audio be? AAC?Kevin

Craig Seeman is the guru on this one, but an h.264 codec wrapped in .mp4 is a good choice for playback on mac and pc. Typically for a 1080 file a bitrate of 7-10 Mbps is pretty standard, for 720 3-6 Mbps, and for SD 1-3 Mbps. If you just have talking heads you could lower those numbers. For audio, yes AAC.

Thanks. I mostly use Compressor for this type work; not sure how to do this. If I select MPEG-4 as the video in the custom box, I assume that is the wrapper. How do I get the H.264 codec inside, or is that automatic?

Compressor 3 or Compressor 4? You can’t make H.264 MP4’s in Compressor 3.

I have Compressor 3 and 4. Haven’t used 4 much yet. I see an H.264 main and baseline profiles. What is the difference, and which do you recommend? And for audio, 44.1 or 48kz?

I would recommend Main profile. H.264 profiles essentially set different encoding parameters and options. Baseline is the simplest, then Main, then High. Some devices, older iphones, ipods, etc, are not able to play High profile.
For audio you would want to choose what you edited in.
