Advice on converting video files -- why do they come out with audio/video not synced?

Asked by MissAnthrope (21511points) September 26th, 2009

I’m trying to convert some movies to put on my sister’s iPod (avi to mp4). The original files have audio/video synced perfectly. In addition, some movies converted fine, but certain ones refuse to convert nicely.

It may be related, but I’ve never been able to burn movies to a DVD player format due to this same issue. I even tried several different programs and the outcome was the same, unsynced audio/video.

My computer isn’t new, but it should be fast enough.. dual core processors, 2 gig RAM, and I also shut down all programs while doing video conversion, including internet and anti-virus program.

Does anyone know why this is happening? Any suggestions for system settings, or a different program, or anything? It’s very frustrating.

additional info would be helpful:

OS? Specs? (video card), programs being used,

also, try playing the avi’s in VLC player, sometimes that can detect and repair avi files that are broken.

Thanks for your help.. let me know if you need any more info than this:

XP Media Center Edition, version 2002, service pack 3
Dell Inspiron E1705
T2250 @ 1.73GHz (Intel Core Duo)
1.73 GHz, 2 GB RAM
ATI Mobility Radeon X1400

For converting the files, I’ve been using Prism, but am definitely open to suggestions if you know of something better. :)

With the VLC player, I’m able to adjust the audio to match up with the video.. is there a way to save it like that?

patg7590's avatar

yes.
there should be an option to export.
also try handbrake for all your encoding needs. Its free (might even be open source idk) and I’ve never had any problems.

patg7590's avatar

did VLC say anthing about the avi being damaged? or were you just able to sync the audio and video using VLC?

MissAnthrope's avatar

No, VLC played it with no message or anything. I went into Tools > Track Synchronization and manually adjusted the audio advance. I’ll check out Handbrake, though. Thanks for the suggestion. :)

Let us me know how it goes.

In VLC, I can’t seem to find an “export” option, there are a lot of “open” options, and a “convert/save” option, but that looks like it’s a whole separate process, not just saving the file. Going to try the program Super and if that doesn’t work, then I’ll try Handbrake.

on osx VLC I have an option call the Streaming/Exporting Wizard.

Hey, patg7590, I wanted to thank you so much for the Handbrake suggestion! I really had just about given up and didn’t expect these particular videos to convert nicely at all, but I downloaded Handbrake to give it a shot. AND LO! It worked! Miracle of miracles! Seriously, you have no idea how many hours I’d put into this. Handbrake is the first program that actually churned out a perfect video from the stubborn video files.

So thanks sooooo much!! Lurve x100!

yeah, Handbrake is pretty much awesome.
You’re welcome :]
