Convert old .AVI files to???

[DotCom2]

I have some old AVI files (2008) I want to convert to use in iTunes and therefore iCloud.
What is a good converter tool I can use and what file format is best to convert them to?
TIA

MPEGStreamclip will convert for you, and .mov(Quicktime) or mp4(mpeg-4) will be ok for iTunes.

HandBrake.fr should also function quite well, it has several templates for i-devices and iTunes.

While MPEG-Streamclip is a good tool, it it more cumbersome to use with all its settings and such, but like HandBrake, it also has a nice batch function to transcode several or all files in sequence with one set up instead of doing every file at once.
