Drops To 0fps While Rendering & Crashes

Happening on various videos at various sections. Render drops to 0fps & crashes after stopping.

DR 16.2.7.010
2019 Mac Pro
Big Sur
W5700X

Try Catalina or, for Big Sur, 17.1 (backup first!!!).

Unfortunately no 17 available in the app store yet.

OMG, so you got the App Store version. Sorry for that!

I know - it's actually been a devastating couple of years.

Do you have any Fusion comps in the timeline?

What specific source material are you using? What resolution? And what format are you rendering to?

We've had good luck with the 2019 Mac Pro, but we threw 256GB of RAM and a Radeon Pro Vega II Duo at it, and that seems to help quite bit?

When all fails, cutting the render speed usually helps reduce the stress to the system a bit. I'd rather wait an extra 20 minutes for a render rather than have one that crashes or hangs.

Hi Marc,

Mix of RED, FS7 & A7. (6K & 4K) to ProRes 422 4K.

Yes i think its an issue maxing out the GPU & have a second on the way.

How can i reduce the render speed? I read someone mention this & cant find a way to do it.

In the Render Settings click on File and you will see it. Speeds are expressed in frames per second.

Ah found it! Thank you Charles. Let's see how it goes now.

Hi all,

I have the same problem, rendering gets stuck on certain frames without an obvious reason.
I tried slowing down the rendering as advised, but it didn't fix the problem for me.
I am attaching DVR log file and the NFO of my system:

I'd appreciate any help!
Thanks

What's the source of those media?

What's the source of those media?

Many different devices (smartphones, cameras, a variety of formats, but all converted into the same).
The strange thing is that DVR doesn't get stuck at the beginning of a specific file - I would guess there's a problem with the file - but it gets stuck in the middle. It renders correctly up to a certain point and the stops.

Is there any way to tell DVR to "skip" a problematic frame?

Not really. Take out all phone footage and try again.

The project with the issue is a compound timeline made of 11 timelines. Somehow, when rendering each individual timeline on its own, the problem doesn't repeat.

I don't think it is a workstation resources issue, as they are sufficient for the project, and the resources taken to render each individual timeline are the same as to render the whole composition.

I don't know what's the cause.
