Eddie Lotter Apr 16, 2009 7:05 AM (in response to Typhoon859)Research on the Internet is so easy (and faster than waiting for an answer on a public forum).
See this pagefor a discussion of both profiles and levels.
Cheers

Colin Brougham Apr 16, 2009 7:24 AM (in response to Typhoon859)Profiles outline/suggest certain encoding/decoding capabilities of a given video compression standard, like H.264. For example, the High profile enables B-frames and CABAC encoding. Levels are a means of ensuring that a hardware decoder can properly decode a stream. For example, an iPod can play back Baseline profile, Level 3.0 encoded video, but nothing higher. Higher profiles and levels enable other hardware, like Blu-Ray players. For the most part, you can ignore levels when encoding for computer playback, and only concern yourself with profile. I pretty much stick with High@4.1.
The link Eddie posted has a ton of information, but here's a good article from Jan Ozer that puts it in more accessible terms.

Typhoon859 Apr 16, 2009 10:13 AM (in response to Colin Brougham)Thank you. I understood all of that besides "High profile enables B-frames and CABAC encoding", lol, but that's okay. Umm, maybe you know, I didn't see those settings in the x264 codec when I use it. I'm guessing it has some sort of default. Might you know what it is? I did however find there "Partition Decision" which has a choice from 1-6, and 6b. I always use 5 which says "High Quality". 1 says "Fastest", 6 says "RDO", and 6b says "RDO on B-Frames". If you would be so kind as to also explain to me these next three items - I left them at their default percentages. Also on the x264 codec under the "Rate Control" tab, there are these three things lised: "Keyframe Boost" @ 40%, "B-Frames Reduction" @ 30%, and "Bitrate Variability" @ 60%. I can guess what they mean but I'm not sure. I like the way you explain. Guides are always too technical.
