The following video file formats are supported by iPod touch:
H.264 (Baseline Profile Level 3.0) Â
MPEG-4 (Simple Profile) Â
A song encoded using Apple Lossless format has full CD-quality sound, but takes up
only about half as much space as a song encoded using AIFF or WAV format. The same
song encoded in AAC or MP3 format takes up even less space. When you import music
from a CD using iTunes, it is converted to AAC format by default.
Using iTunes for Windows, you can convert nonprotected WMA files to AAC or MP3
format. This can be useful if you have a library of music encoded in WMA format.
iPod touch doesn’t support WMA, MPEG Layer 1, MPEG Layer 2 audio files, or audible.

If you have a song or video in your iTunes library that isn’t supported by iPod touch,
you may be able to convert it to a format iPod touch supports. See iTunes Help for
more information.
