Transcoding video by Linux for iPod touch

This theme is very interesting now in the Internet cause iPod touch is popular now and for people who using Linux very important to know how to be without Windows on iPod touch. Here I'll post some info how to use Linux for it.

But before, some info: "Transcoding is the direct digital-to-digital conversion from one lossy codec to another.
Transrating is a process similar to trancoding in which files are coded to a lower bitrate without changing video formats. Changing the picture size of video is known as transsizing."

OK, I did some tests with video files transcoding and did try to upload them by iTunes on iPod touch. Many of them weren't accepted as native for iPod touch. Some of them were. So, I wrote the script for Linux you can download from HERE

Its just show necessary settings which iTunes accept as natives and upload video files to iPod touch as is.

Cheers
