Synchronize AVI audio and video

Synchronize AVI audio and video

Ever downloaded a nice movie from the internet (Bad you), or didn't correctly synchronize your audio and video when creating your own family video's? Personally, I think there is nothing more annoying than a video where the audio is behind, even if it is for one second. So here's a small how to, to get your sync back so that you'll fully enjoy the movie. Get your bag of popcorn ready!

Sync AVI

First, check if your file is already AVI. If it isn't, convert it to an AVI file. I would recommand WinAVI, but there are many similar programs on the net that can do the same trick. If you have the AVI file, go to the next step.
Download VirtualDub. VirtualDub is a video capture/processing utility for 32-bit Windows platforms. Install the program on your computer.
Next, start up VirtualDub. Open your AVI file in the program by going to "File", then "Open Video File" (Ctrl+O).
Now go to "Video" and select "Direct Stream Copy".
Again, go to "Video" and now select "Frame Rate" (Ctrl+R).
Select the radio button which has the following text: "Change so video and audio durations match". You should end up with a non-standard frame rate.
Go to "File", "Save as AVI" (F7). After saving the video, try to play it in your media player if it is in sync now.

There you have it, a fully synchonized movie. The only time this trick doesn't work, is when the audio and/or video rate changes during play. It's almost impossible to fix this. Now, lean back and enjoy the movie.

Did not work for me, said the Xvid codec wasnt compatable or something. I was using an AVI file.

Install DivX installer. I it does not have a windows x64 option for download, so you must install the virtualdub x32 (as opposed to the x64 option...even if you have windows x64) so that they can be in the same program folder. Otherwise, virtualdub won't be able to find the divx decompressor. Try that, it worked for me!

B.Oliver - Join 35 Avi's and then sync it?

2009-09-24 16:21:15

I joined 35 small avi's with virtual dub using the frame rate option "Change so video and audio durations match". It got out of sync even so. Is there a way to sync the entire avi without having to join+sync them 1by1?

pura - codec error

2010-01-13 03:16:21

wanted to know if there is a solution to the error " couldn't locate decompressor format for XVID" , which is denying me the access to open the video file I intend on fixing up. the video file is of avi format.

Easy ways to convert swf video files to mp4 format with the help of SWF to MP4 Converter. The converted files shows the perfection.

I found it only worked perfectly if I put it on "Full stream copy". Then it worked great. Thanks!

Didn't work for me, ran thru without a hitch but didn't sync the file? Any other ideas? Thanks! :evil:

eric	2012-01-26 17:33:42

Didn't work with my video, but under the audio option,
Goto Interleaving (Ctrl+I)
There you can delay the audio track by the millisecond

P R	2012-02-17 14:02:14

Good effort, thanks, but it doesn't work. In fact, when you load the file and check the file information, the differences between audio and video lengths do not correspond to the real delay between both. You should not say with such confidence that "Here you have it, a fully synchonized movie". It's not true. Your solution does not work.

Couldn't locate decompressor for format 'XVID'(unknown)

VirtualDub requires a video decompressor for windows(VFW)compatible codec to decompress video.DirectShow codecs,such as those used by Windows Media Player,are not suitable.
