“Exception:Audio Underrun”
Help!
I am an assistant editor attempting to print to tape. This reel has been stopping at the same exact frame of tape and the error message “Exception:Audio Underrun” pops up. The system I am using is not mine and was setup by an outside company. There are 4 media drives already in the system and I was not here when it all got digitized. Please I need help! I have 5 reels to output and this problem is happening on Reel 2. (As of now I am going to attempt the other reels.)
I tried rendering. When I render in/out it says I have 2 effect to render and I click to render, but nothing happens. Any idea how to fix that?

At the frame that keeps messing up–is there an Audio dissolve? Audio Underrun typically means the audio can’t keep up with the video–a hard drive issue, or maybe a corrupt render. Try removing any audio effects around that frame and reapply them. Also, you might want to match frame the audio where the stoppage is happening and recutting it into the sequence. I’ve seen that help too.

Awesome thanks! I will give that all a try. As well as a good old fashion re-boot.

You also may want to mix down (1 video, 2 audio) a portion of video and audio surrounding the affected area. It’s a bit of a kludge but it works sometimes.

I agree with David about mixing down the video. Audio underrun generally isn’t because of the audio, ironically. Audio files are small and easy to play through the system, usually the problem is something with the video, which takes up the most computer resources such that there isn’t enough left for the audio.
I’m sure if you wanted to find the problem and trouble shoot you could take off and replace effects, copy and move things to new timeline or you maybe on a system with some older drives(that’s what always used to get me) eventually you’ll locate where the issue is…but since you seem to be under a deadline, I suggest mixdown the video in the area of the underrun-create a new top layer and throw it on the top. As it’s a mixdown it should play in real-time. Keeping it on top will allow you to make remove it and make changes later if necessary.
You could mix down the entire sequence if you absolutely necessary, since it’s mostly rendered anyway it won’t take an extraordinary time…but I’d only do that as an absolute last resort.
