Solution for crashing 15beta?

Dear all,

Upgraded to 15 Beta, because 14 kept crashing. I accept the crashes as it's a beta version. In general it crashes on many different, simple operations: playing from the timeline, copy/paste, scrolling through footage etc. But now I cannot export my sequence in the 'Deliver' page anymore. It keeps crashing, so it's getting pretty serious now. Every time again it crashes at another point in the timeline.

Does anyone encounter the same problem and found a solution? Should I upgrade to High Sierra? Can I somehow find out if it's caused by hardware or OSX version?

I click send crash reports after most of the crashes.

Project details:
Current version of DVR 15.0.0B.046
It's a large project, containing over one TB of footage.
Footage format: 3840x2160, MXF OP1A, XAVC Intra, 48 kHz
Effects applied: only Sony Slog3 Lut, some colour correction here and there.
Using 2 G-tech harddisks, a Firewire (with Thunderbolt adapter) and a thunderbolt disk.
No additional/external hardware.

Thanks, T.

FireWire 800 or 400 sounds way too slow for UHD XAVC Intra.

UHD is quite demanding for a GPU with 2 GB VRAM (see config guide). Plus: are you sure that it's not using the Intel GPU for processing?

Do you experience the same problems on the iMac? Which GPU does that one have?

High Sierra is not needed, Sierra is enough.

Thanks Seth,

The problems occur on the iMAc. Firewire might be a bit on the slow side, but in Premiere it runs perfectly well. And it shouldn't be a reason to crash really. This is a project I've been working on for a year and got through it acceptably well with DVR, but the current crashes are new and force to me to change software..unfortunatly..

Thanks Uli,

I checked GPU processing mode and changed it to CUDA (was convinced, without checking, it was on it..). It exported without crashing!! Will post later if this also solved most crashes.

You have a Radeon GPU, it can't use CUDA. But you can try to switch between Metal and OpenCL.

BTW, it's quite courageous to use a beta software for such an important project…

Finally, this discussion should take place in the beta subforum.

Thanks Uli

- Ofcourse your right about CUDA.. Fiddling around with it made it possible to export again.
- I had too many problems with 14, so tested 15 for a while and accepted the crashes. But not able to export was a bit too much..
- Usually work with another program, but I like the concept of DVR and for this particular project I wanted to have direct access to its Color Correction capabilities. When it works well, I'll immediately switch to DVR.

Cheers, T.

For what it's worth, R15b4 has been pretty damn stable for me, no crashes whatsoever except for when using Fusion. The one time where I had incessant crashes in R14 (and I suspect also in R15) I narrowed it down to drive speed. The fact that Premiere didn't crash off the same drive doesn't mean anything — two different apps behave differently.

I was amazed at how buggy Resolve can be if the footage is coming from a slow drive. Remember that it's not just the interface, it's the drive contained within it. For instance there is a huge difference in performance between cheap external USB 3 drives and more expensive ones.

Use the Blackmagic Speed Disk tool to get a sense of how fast your drive is.
