PSP Video Format
The video codec supported by the PSP is a proprietary variant of the H.264 codec closely related to DivX. The format is also referred to as the Memory Stick Video Format. The audio codec used is AAC.
Before loading video onto your PSP it needs to be transcoded using one of the tools listed below. Some compatible (Sony) devices may be able to produce video in the correct format, and therefore may not require transcoding.
The PSP manual states that the maximum supported bit rate is 768kbps The native screen resolution is 480x272, which means it has an odd aspect ratio of 1.764, not quite 16x9. The device supports several scaling modes (normal, zoom, full, original).
File Naming Convention
When storing video on the card a strange file naming convention is used. All video files and thimbnails need to be stored in a folder called: /MP_ROOT/100MNV01.
Each video in this folder is represented by an data file and a thumbnail file called: M4V00001.MP4 and M4V00001.THM. The 00001 component of the file name is incremented for multiple videos.
The thumbnails are simple 160x120 JPEG images stored with the .THM extension. Note that the title of the video is stored in the header of the file.
