File will not play back in any player other than Virtual Dub

[Emanuel Levy]

I have a video file (no audio) that was originally made with Microsoft Movie Maker. When I load it in Virtual Dub it plays back fine. When I try to play the file in any other media player it pauses frequently. I an not re-create the file from scratch but I need to fix this so that I can play the file in VLC and eventually convert it for YouTube.

I need to accomplish this today and all help is greatly appreciated.

Upload the file here or at least post the MediaInfo information.

As a first step you can try remuxing:
ffmpeg -i "input" -map 0 -c copy "output"
Is the file asf/wmv? Then you may also try AsfBin in case ffmpeg didn't do the trick.

That said, I don't really understand why you need it to play in VLC if your plan is Youtube uploading. Edit and export it through e.g. VirtualDub either losslessly or with very high bitrate. Youtube will compress it to (relatively) low bitrate at the end of the day anyways.

I wanted to play it in VLC because that is what the person previewing the work is using. How can I add the audio track to VirtualDub and then save a new file?

The Audio is in 16 bit WAV made with Audacity and the video is now in m2v but I do have the original AVI that was edited in Virtual Dub. I think when I did the editing I didn't pay attention to P K and I frames and that caused issues

Audio->Audio from other file

Then either File->Save as AVI or use the export options. Note that if you don't select video/audio compression before saving as AVI the file sizes will be huge.

Sneaker when I try to play it back from within VirtualDub the audio is stopping and starting. I am concerned that the finished one will have the same issue,

Try it or you will never know.

It is taking 52 minutes to encode.I will post back

And it had the stuttering problem still.

[Budman1]

Stuttering can be caused by large, high resolution video being played on a possibly slower computer, especially with Virtualdub using several filters. This would also explain the long encode time. What is the resolution?

As sneaker pointed out, it is always a help if you post the mediainfo information here.

Virtualdub should not be used as a player ... the stuttering could simply be the program is struggling to handle the file during playback which is well known issue.

Process the file then confirm audio is intact

You have me at a loss here. First you say VirtualDub plays it without problem. The only thing we changed is that we added the wav audio track, right? So why would the output suddenly stutter?
Please post MediaInfo logs of input video, input wav and output result.

It's not your PC being too slow to play the file, is it? If the output file is uncompressed video (result of not activating compression in VirtualDub) it may require a fast HDD for real-time playback.

Without audio it is not forced to synchronize anything, "plays fine" could mean playing at 28fps when the source is 30fps.
