converting mp4

[iceborne]

i just made an mp4 file to play on my palm tx. thing is, the damn thing doesn't play at 29.97 like i want it to. is there any way to convert the file down to 15 fps without having to reencode?

Nope, frame order is too important, every frame depends on the frames behind (or around) it. You might be able to chop out b-frames and retime it, but I don't know of an automated way to do that, and still won't work where there's few or no b-frames.

i didn't use any b-frame on this one since i figured the tx couldn't handle it anyway. but your comment was what i thought from the beginning. just thought someone knew something i didn't know. thanks anywayz

it wouldnt work anyways coz avc uses b.frames as reference as well.

it wouldnt work anyways coz avc uses b.frames as reference as well.well depends on whether you enabled that feature (b-pyramid) or not

but he didnt use b-frames, so he needs to reencode anyways

that's on x264, other encoder may do it automatically. however, yes... he needs to re-encode
