Avid has been great except for today. It stops responding and for some reason doesn't continue playing the sequence on one part of audio.

I have made a 4 minute video, but when I render/export it to mp4 file it stops at 30 seconds and displays this:

Exception: std:: exception,what:ameAMAFI:AMAFIAudioWriter::Execute(): TIMEOUT - pipe stall detected

Does anyone know a quick way to fix this? The project is due on Monday morning. (4/01/21)

Hi NateWP,

It would help to know your system specifications. Which specific version of Media Composer are you using? Which specific operating system? Processor? Amount of RAM? Video card? Is your media linked, transcoded, or imported? Where is your media stored? Look at my profile at the bottom of this post for an example.

If you fill out this information in your profile, you won't have to type it out every time you need help.

 Specs:

Media Composer 2020.09 w/Symphony/SS/NC/PF options, Intel(R) Core(TM) i7-9700 CPU @ 3.00GHz, 16GB RAM, NVIDIA GeForce RTX 2060, Windows 10 

The source media was linked before and it was fine, it's just the past few days it's caused a problem. I tried transcoding the material but it doesn't work and won't let me transcode some of the png image files.

I have everything I need on the sequence, if I transcode everything will I also need to transcode the sequence/get the transcoded footage to the sequence somehow or start all over again? Starting again is something I really don't want to do because I won't have the time to do it for the deadline.

NateWP:

Try exporting just the first half of the sequence, and then try exporting just the second half. If one half fails and the other half succeeds, then you know there's corrupt media (either a clip or an effect) in the half that failed. Keep trying to export shorter and shorter sections until you narrow down where the problem is.

That's what I'd try first.

I've always found that creating a Video Mixdown to ProRes solves many problems. (Make sure your topmost TV is active to see all your video tracks.) I would duplicate my sequence.  Do an edit from the video mixdown replacing all of the other video tracks on the duplicate timeline.  I would then try to export that.  If that fails, I would be surprised.  I usually export to ProRes for a final master and use another app to make mp4s, etc.  If ProRes is not an option, obviously you can use DNxHD or DNxHR.
