H.264 produces better images but is much harder to encode, especially given QuickTime Pro is so far the only sure way to encode it...and QuickTime Pro is horrible. MPEG-4 is far more common and more easily encoded.

if you have short videos at an iPod resolution, use H.264 for best quality.

If you want to encode high res for TV output, use MP4.

MP4 and MPEG-4 aren't exactly the same thing. H264 is an MPEG-4 codec. MP4 is a wrapper. You can have h264, Xvid, or Apple's MPEG-4 codec, among others, in an .mp4 wrapper. H264 has a superior quality-to-bitrate (quality-to-size) ratio than any other MPEG-4 codec presently out there, but it takes longer to encode.

OK, I will try to clear this up eventhough many people have done good jobs at doing so.

The iPod is compatible with two video formats: standard mpeg-4 (h.263, it will be called mpeg-4 video from now on) and mpeg-4 AVC (h.264, it will be called h.264 video from now on). h.264 video is better than mpeg-4 standard video if each video is encoded at the same resultions and same bitrates. A 800kbps h.264 video has the same quality as a 1000kbps (1Mbps) mpeg-4 standard video if each video is encoded at the same resolution (ie 320X240, the iPod screen's resolution).

It all really depends on what you want. If you plan on just watching video on your iPod, don't have a high resolution PC monitor, and are hooking your iPod up to a small (25" or less) standard TV. The iPod can handle h.264 video at a maxium resolution of 320X240 and a maximum bitrate of 720kbps. However, the iPod can handle mpeg-4 standard video at a resolution of up to 480X480 (and subsiquently 720X320) and a maximum bitrate of 2.5Mbps (2500kbps). This means that for larger TV's (>25"), the mpeg-4 standard video format would be better because you could encode videos at almost a twice as large resolution than h.264 videos and a much higher bitrate than h.264 videos. You will be able to see the difference between a 720kbps h.264 video and a 2.5Mbps mpeg-4 standard video on a 30" TV (with mpeg-4 standard video looking better). However, on the iPod's screen, they both look about the same due to the small screen size of the iPod.

Hope that helps. It can all be a bit confusing at first as there are two different formats, numerous different resolutions, and even more bitrates you can encode at. FYI - all videos downloaded from the iTunes music store have a maxium resolution of 320X240, a maxium bitrate of 720kbps, and are either in the h.264 (most of them are in h.264) or mpeg-4 standard video formats.
