Just another note about the SageToiPod software. It uses ffmpeg as a video encoder. When you run the SageToiPod software, you will see a text box labeled "FFMpeg encoding parameters." By default these parameters are "-f mp4 -vcodec mpeg4 -s 320x240 -r 15." This sets up ffmpeg to use the mpeg4 codec with a video size of 320x240 (correct for the iPod) and a frame rate of 15fps. I haven't had much success with the h264 codec, but you can give it a try. I haven't found that higher frame rates improve the video quality, but significantly increase the filesize. Feel free to play with the parameters if you like. If you want to learn more possible encoding parameters, find the ffmpeg.exe file in the install directory, and run the file without any parameters from the command line. It will spit out all the possible encoding parameters.
