Slight problem with MP4 play back ( FPS Q)

[tomdbomb61]

im using a 3GP converter to convert mpgs etc into MP4 format.

i converted one music video with a 25 FPS rate. which played fine on my pc, but when i put it on my PSP the sound seemed to go racing off ahead of the video, making them out of sync very quickly.

i then converted the same file using 15 FPS and it now works fine on the PSP.

anyone else found the same wen using a 25FPS setting?

It all depends on the video itself before it was encoded and or compressed. Some videos dont require a fast fps in order to work well. If you overclock the speed of the video it can sometimes cause certain aspects of the video such as sound to go out of sync easily.

Another reason maybe due to the fact of the extension such as AVI, MPEG, VOB etc . Depending on the extension before it was encoded can have a dramatic effect on the outcome of the video.
