Question

Missing audio for some clips in exported output

Hi,

 

Have you ever encountered an issue in Premiere Pro when an output lacks an audio for some input clips?
I'm not able to find the pattern of this problem, but in my case it appears mainly for timelines that consists of many clips (H265 4k). When playing back the timeline, all clips play correctly.

 

As an output I use mp4 multiplexer, video of H265 and audio of AAC 320kbps. When export only audio, the problem doesn't exist anymore (but I have to remux it with video exported separately).

Hi, aaab,

Weird. I wonder what's going on there? I can understand how you might feel; the issue is super mysterious. Sorry! I suspect the source files are not providing the data during the export. Can you try a test by transcoding a suspect source file to ProRes LT and then exporting it? See if the sound is retained on export. Let us know if the test was a success, or not.

 

Thanks,
Kevin

Hi Kevin,

I've run two tests as you've asked:

1. I've changed the originally audio-unexported source clip into ProRes LT transcoded one -> the output contains a sound for this clip.

2. I've deleted all the clips following the original suspect source clip from the sequence (it remains the last one in the sequence) -> the output contains a sound for this clip.

I think the issue is of non-deterministic nature 😞

That's weird. One thing to try is to copy/paste the clips into a new sequence and then export that one. Does that do anything to fix it?
