Choose one of the predefined profiles or set the output properties, but for novice users it is recommended to select one of the default PSP profiles.
If you would like to change the video file parameters you can edit the following information but you will not be able to change the Frequency parameter and it will always be 24,000 Hz for Sony PSP. The File Type parameter must also be set to PSP so that your Sony PSP could read and playback it properly.
Resolution: 320 x 240 (QVGA)
Nonstandard resolutions can be used after patching MP4 files, but are still limited to the 76,800 pixel resolution of QVGA.
Codec: MPEG-4 SP (Simple Profile), which has different headers than the more common MPEG-4 formats. As such, many programs that export to MPEG-4 create files that the PSP™ won't play.
Sampling Rate: 24000hz only
1-768kb/s & 1500kb/s. Any combination of video and audio bitrate that is equal to or less than 768kb/s is acceptable (i.e. 640kb/s video + 128kb/s audio = 768kb/s total, or 300kb/s video + 32kb/s audio = 332kb/s total) The bitrate you select will directly impact both the quality and the file size of your video. The PSP™ also supports a bitrate of 1500kb/s, but no bitrates inbetween 768kb/s and 1500kb/s.
