compound audio glitches

just wanted to give an update on this (for me) long persistent issue, where audio glitches are randomly appearing when using compound clips (the compound as an audio source). To describe it, it's "choppy". small portions of audio repeating one or 2 times, or silent portions when it should not be silence, etc. It is still happening now and then. I'm currently on 18.6, but i also found this in 19beta, on a mac studio ultra m1, and m2. The hard part is that i have no idea how to reproduce it, but in my long-term experience, i found it mostly happening in longer timelines (1hour plus).

The solution for now is to flatten the compound clips, but this is still a workaround, not ideal. I'm using 48k 24bit wave files in this case. It also sometimes works to just add a cut to the audio file inside the compound clip.

Especially with longer timelines, this can really break your workflow. It's that i know about it, and can anticipate, but it can easily ruin a project if one is not aware, as it can sneak into the final delivery, making it a serious issue.

I agree and am a little upset that this still has not been fixed by Blackmagic as I've posted about it in the past and we're still getting bugs in exports when we don't decompose (which makes a mess of our timelines on these long webinars we're editing).

Have you submitted this as a bug to DR? I can't remember if I have, but if you haven't, I will.

i'm not sure anymore, i think so. But that might have been a report with a much older combination of OS and hardware than i'm using right now. Although i'm also 100% sure that this is not specifically one combination as i experienced it with all kinds of setups over the years.

the thing that bothers me the most is that it almost feels like it is being treated as a low priority thing, as these topics always seem to fade away, while it really affects the reliability of the software. But i'm sure that if it was easy to fix, it would already have been fixed.

It's just that these issues are never acknowledged.. which i can understand from a business point of view. but it makes it almost impossible to anticipate as a user.

Rick, do you have any audio effects applied inside the compound clip? I agree that this could drive someone bonkers. I wish BMD would publish guidelines for working with nested audio.

No audio effects here. One of my compound clips is just a music track and four sound effects. Some of the sound effects have EQ applied within the Audio tab of the inspector and some have clip speed changes. Other compound clips have an mkv within them. The glitches are random and don't occur in predictable places, and they change with every render. They're also not noticed during playback.

For me they often are

@steve; both with and without audio effects
