green choppy playback? ipod g5

[pixeldotz]

so i've been playing around with megui the last few days and was wondering about ipod encoding.

i did do some search for the word 'green' and couldn't find a relevant topic.

i did find that x264 will crash on some fps, but i dont have that issue.

here's mine.

i encode with the xvid coded in megui using the ipod profile set to a bitrate of 384 (suprisingly enough looks very clean). im testing the x264 one right now, but with xvid the movie plays in quicktime but choppy (playback 8fps when movie info shows 28.978) and on my ipod the video plays but skipping with random green squares occupying more than half of the screen. the ipod looks perfect when i fast forward or rewind.

kind of seems like itd be a fps issue since it looks fine when fastforward or rewinded. but megui outputs no errors nor does it crash.

edit: tested with the x264 codec. while it does play fine in quicktime now, i can't upload it to my ipod. also, i would prefer to use xvid since it encodes at about 30fps whereas x264 encodes at about 6-7 for me. :(

also, sorry if this is in the wrong section. kind of hard to differentiate between container and gui when you use both.

which resolution are you using?

just tried 352x192 and still get choppy playback with green on the ipod. (xvid)

edit: 352x192 allows me to upload it to the ipod and it looks perfect (x264)
but the encoding is doubled down what xvid does. is there a workaround or something im not setting up right that keeps quicktime it at 8fps when i use xvid for coded, and totally messes it up on the ipod.

well, after some research. i came across an older thread i had overlooked before. the problem with the xvid encodes was BFRAMES! turned those off, and everything is fine now. :) sorry for polluting the boards with something i could have found earlier.

doing a movie right now. last time the encoding stopped at 17 megs (6 minutes into the movie) but that was with using xvid_encraw. im trying to see if it stops again with mencoder.
error log said everything was fine.

max resoultion for iPod for x264 is 320x240.
