Out of Sync Picture & Sound

[DivX_Newbie]

I have episodes of a TV show recorded for me in avi. format, which I play in either DivX Player or Windows Media Player. The picture and sound quality are both excellent, but out of sync. The picture is up to three seconds behind the sound.

Is there anything I can do about this as it's starting to annoy me?

Many thanks.

I am guessing you would use a program called "VirtualDub". You would extract the audio to a ".wav" file, then re-encode the audio and video together in synch.

I am having to flash back to my video editing days of re-authoring VCD's, so my suggestion might be alittle off. I would suggest waiting for the member "setarip" to reply to this, as he is very knowledgeable about this form of video editing.

Hi, thanks for the reply.

Unfortuately, I cannot do anything to the discs at all-- they have been made as Read-Only so I cannot make any adjustments to the actual files themselves. I can't even change the titles.

"I cannot do anything to the discs at all"
Sure you can - Simply copy them to your hard drive. Then:

A) If the difference between audio and video is constant throughout the video:

Load the file into VirtualDub, VirtualDubMod, or NanDub.
Set BOTH "Video"(VirtualDub, VirtualDubMod and NanDub) and "Audio" (VirtualDub and NanDub - VirtualDubMOD>"Streams>"Stream list") to "Direct Stream Copy".
From the "Audio" dropdown menu, select "Interleaving" (For VirtualDubMOD, rightclick on the listed audiostream and then select "Interleaving")
Under "Audio skew correction", set an appropriate number of milleseconds (positive or negative) in the box labelled "Delay audio track by"
Save with a new filename

B) If the difference increases as the movie plays:

From under the "Video" dropdown menu, select "Framerate" - and select "Change so video and audio durations match"
Save with a new filename
