H.264 Ipod Mp4 Movies?

[Kramy]

Please stop confusing people about H.264. 4.0 and 5.1 are not profiles, these are levels. Levels define required decoder performance (bits per second, pixels per second and memory availability) while profiles define decoding capabilities (like B-frames, arithmetic coding, interlace tools).

Sorry, bad terminology on my part.

The difference between "Profile", "Level", "Preset", and "Tune" isn't very clear to me - but they're all required to be something or this encoder GUI won't start x264.

I usually go High, 5.1, and change the rest based on the content.

Edit: To anyone that has a working Pandora(Craig, etc.), if I send you a 20MB vid, can you see if it plays?
