How to transcode video for iPod, iPhone, PSP, PDA, or other portable devices. There are a lot of different ways to transcode video for use on portable devices, both automated and manually. Some of these methods may be out of date and no longer work.
Contents
nuvexport
nuvexport is a utility that can be run from the commandline. You select the output format, the videos you'd like to transcode, and it does it for you. It does not automatically transcode for you, however
See Nuvexport.
mythtranscode
mythTV can automatically transcode videos after recording them using mythtranscode. It can only transcode to RTJPEG and MPEG4, however, which may not be what your device requires.
mythnuv2mkv
See Mythnuv2mkv.
nuv2avi
See Nuv2avi.
3gp Video
Transcoding video to 3gp format for mobile phones
