convert itunes bitrate

Whenever I try to convert videos from my Camera to Itunes it just won’t work! Its the right file type too…
It will be on my iTunes just fine but won;t go on my Ipod. These are videos that I taped off my camera and is in the right file for itunes due to videora ipod converter. But they won’t go on my ipod.
Ive tryed everything. Though on videora it says its due to bat bitrate and stuff, but what is that and how can i fix it?
If it is a camera designed to take pictures, it won’t work. It will only work if you are using a video camera, even if the picture camera takes videos. I have tried the same thing many times, but it doesn’t work.
