MPEG-4 vs. H.264, for the Video Ipod

So, I looked back into the issue of Mac User, which details the codec specifications for the video Ipod and here is what I have found:

H.264 is a codec designed to produce a very high quality picture with a very small size. This is very useful is you are trying to cram 80 feature length movies onto your video Ipod. However, the downside to H.264 is that is takes a lot of brain-power to decode it. Therefore, the resolution must be fairly small for the Ipod to play it, and, it takes longer to compress an H.264 file through a program like Handbrake.

With MPEG-4, the file size might be a bit larger, but it is possible to compress a feature length movie at 720 pixels wide and to play it on your Ipod at this resolution. Therefore, if you connect A/V cables, you can play movies out of your Ipod onto your television and have them look crystal clear. Your Ipod, will play videos compressed with eithere codec (MPEG-4, or H.264).

On the next post, which will be the last about the video Ipod, I promise...I will post the formula for knowing whether your Ipod can view videos, depending on their resolution as MPEG-4 and H.264.
