Audio / Video -- Geeks inside

[ryanfx]

Hello fellow geeks,

I am trying to rip a DVD (home movie of course) onto my computer and put it on an IPod Video. I rip it off the DVD into .vob files. The files work fine, the audio and video are perfect. The problem comes where I try to encode them to ipod format. The audio and video slowly but surely get out of sync, where later in the video it gets off by a few seconds. I've been reading something about that most videos are encoded at 29.97 fps and the audio is almost that, but like .04 off, so it starts adding up. Does anyone have any experience with this, or know how I can convert it correctly? I am using videora to convert it to ipod format.

ill preface this by saying i have never used an ipod video, but i do have a bunch of knowledge about apple in general, and the preferred format for most apple videos is quick time (.mov) format.. again, i dont know what ipod videos play, but if thats an option, i would suggest trying to convert it to a quick time file.

never used the ipod function but from using the software i know it works rather well, DVDFab Decrypter

well I can get the VOB files perfectly. Thats not the problem. It's once I try to convert to MP4 format (which is the format it uses) is where I get the problem =/

the program has an ipod feature in it, like i said, i've never used it but i've seen the function in the program

It's been a while since I backed up my DVD collection to media other than DVD-Rs, but when I was backing them up to DivX I could set keyframes every so often to keep the video and sound synced. Might want to see if there is anything like that for MP4 encoding....

perfect Justin there is a keyframe interval setting - any calculation to figure out how many I need?

I think I used to do them every minute or so, just to make sure that they never got noticeably far off.
