Sound/image not synchronised

[vintagequeen]

I've tried playing a DivX file in a number of programs (BSPlayer, DivX Player, Real Player and Windows Media Player), and I always find that the sound comes slightly faster than the image, making it very annoying to watch.

Is there any way I can fix this?

Any help is much appreciated.

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

Load the file into VirtualDub, VirtualDubMod, or NanDub.
Set BOTH "Video" and "Audio" to "Direct Stream Copy".
From the "Audio" dropdown menu, 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"

Let us know of your success ;>}

Thanks! Unfortunately, VirtualDub won't load the file, saying that it will not use the decompresser used by Windows Media Player. Any advice??

In order to determine which codec(s) you need for a particular .AVI, you should do the following:

1) Load the video file into VirtualDub (or one of its many variants) or NanDub

2) From the "File" dropdown menu, select "File Information"

3) Post (here) EVERYTHING you see (BOTH video and audio information), or post a screen capture .jpg of the information box

The problem is, I try and load the file into virtual dub but it just gives me an error message straight away, which says it couldn't locate the decompresser for DIV3. Any ideas why??

[setarip]

That error message doesn't prevent you from:

2) From the "File" dropdown menu, select "File Information"

3) Post (here) EVERYTHING you see (BOTH video and audio information), or post a screen capture .jpg of the information box


(That message indicates that the .AVI uses the DivX v.3.11alpha video codec)

[vintagequeen]

The error message prevents me from clicking anywhere else, hence I can't get to the file information? Is there anywhere I can download the appropriate codec?

[setarip]

"The error message prevents me from clicking anywhere else"

What happens after you click on "OK" in the error message box?

[vintagequeen]

When I go to "File" the option of "File information" is not available for selection.

"Is there anywhere I can download the appropriate codec?"

Go to:

Thanks, unfortunately I can't seem to get the file to run in VirtualDub in order to make the necessary adjustments. Any other advice?

Install the DivX codec first of all. You should then be able to load the AVI in Virtualdub.

[vintagequeen]

I have all the DivX codecs installed, but it still refuses to load in VirtualDub. Is there any other programmes I can try?

Something that should have been stated in the beginning: what video card are you using and what is your CPU speed?

I am asking this simply because this looks like one of those cases where the CPU is too slow for proper video playback.

[vintagequeen]

How can I find that out? However, I dont think thats the case seeing as all other DivX files play completely normally, I think this one has simply not been encoded properly.

How can I find that out?
Shouldn't you know your computer better than that?

Anyway, as long as your CPU is reasonably fast (I'd put a minimum speed of 500-800 MHz), you should not have any problems with DivX playback.

However, I dont think thats the case seeing as all other DivX files play completely normally, I think this one has simply not been encoded properly.
It could be as you said.

Or this particular file is the first that you have come across that requires more CPU power than the others.



As an alternative, use GSPot to obtain the file information of the file. Simply open the file in the said program, capture the image and post it in the forum for us to see.

In case you need to know how to capture the image:
1. Have the file open in GSpot (as described).
2. Press "Alt - Print Scrn" (to copy ONLY the active GSpot window into memory).
3. Open an image editor program, such as Paint, and Paste the image into it.
4. Save image as JPG.
5. Post the JPG file in this thread.

Cheers.
