AVI files not including audio.

Sandmanlions wrote on 1/2/2018, 10:09 PM

Hey all, I have a bunch of files that are AVI that play fine in Windows media player, but as soon as I open them in Sony vegas pro 14 build 270 they do not upload audio, just the video clip. I have looked around and most of the solutions are to convert the file. Issue is that my projects tend to have 30 or 40 clips. That makes converting a HUGE hassle. Is there a quick fix I have missed?

How were the files created?

It would be useful to get a sample (e.g. on Dropbox, Google Drive, OneDrive, mega.nz, wetransfer.com or mediafire.com) to test for solutions and forward to the developers.

Transcoding can be fairly painless if, for example, you come up with an FFmpeg batch file that can do them all in a batch. There's an example in this thread that you could adapt to your case.

Not sure but wasn't this a known issue with uncompressed AVI and 24 bit audio.

Here is a link to a file like the ones I'm having issue with. https://drive.google.com/open?id=1orfxMzfMbMpTNA8QMDrhr9dahx8tTnFe

There is something wrong with the audio. Neither Vegas nor Adobe Premiere will open with audio. Vegas lists the audios length as 00:00:00. Mediainfo lists it as being 60.83 frames (1015ms). Sound forget will not open the file.

All other programs I have will open the audio. WMP, VLC media player and straight to youtube has audio.

What was the source? It is for sure not meeting a standard.

I can't use the audio of the file in HitFilm Pro either. It's there, but it is distorted and lasts only one second (the length MediaInfo reports). Lightworks does not import this file at all.

What works fine is transcoding the file by ffmpeg and using the transcoded file in Vegas Pro instead. Also extracting (de-muxing) just the Wave audio portion via ffmpeg works fine and this extracted audio then again works fine in Vegas Pro.

So to me it seems like there's something broken in the interleave structure of the file (which may be ignored by some players).

I'd suggest doing a batch transcode. This isn't a huge hassle. Dependend on the software you use it is a single mouse-dragging of the files and once defining your output type and path.
Remuxing would be another choice and even be much faster but remuxing doesn't solve the problem in this very case.

BlackMagic media express software off an intensity pro. I have been using it for years and had no issues until vegas 14 and just ignored it because most of my projects don't use source sound anyway. I'll contact them. Thanks!

If you don't mind, please leave this file on Google Drive for now so we can link the developers to it.

For sure. While it may be a weird file, my hope it to get it resolved because I have a ton of footage that has unusable sound while in Vegas. What a pain in the butt....

Batch transcoding can be so easy in such cases. With an appropriate ffmpeg script all you'd need to do is to drag such files (in one go) onto the batch file and wait until the process is finished.

Interesting. Vegas 11 doesn't show an audio track at all , same with Quicktime. It shows no audio track, yet WMP will play it with audio.
