Crash during UHD+ resolution 3840x4320 using Resolve connector

robinkoehler · 2022-12-23.txt

Hi everyone,

I am having some trouble with a non-standard UHD+ resolution of 3840x4320. Voukoder crashes after 20-30 frames into the encode. The same project renders fine if I select HEVC (AMD AMF), and it also renders fine if I reduce the output resolution to something more reasonable.

Davinci Resolve 18.1

AMD 6900XT

Windows 10

HEVC (x.265)

General purpose 4:2:0 8bit recommended preset (but have tried pretty much all the others too)

Latest 12.1 and connector

Log attached.

This is a weird one because I can export without issues on an almost identical machine (5950x, 6900XT, W10, DR18.1).

Thank you in advance!

Best wishes,

Robin

It doesn't crash. It actually finishes normally.

But I guess you tried to export more than 30 frames, right?

Correct, more like 150,000 But resolve also complains with "Failed" and critical exception bad allocation, or failed to encode video frame (it varies). Sometimes the program remains responsive, sometimes it takes the program down, sometimes it even takes the GPU driver down. I have uninstalled and reinstalled the Radeon Pro driver and tried the normal drivers as well, same result.

Do you have low level debugging enabled in the voukoder settings? If not please enable it and send a logfile again.

Does the machine on which this is working have more than 16GB ram? 16 GB seems to be a bit low for 3D UHD encoding. Maybe this is related.

Interestingly: yes, the working system has more RAM (64GB), HOWEVER I used to be able to do this without a problem on 16GB, this was with davinci resolve v17, voukoder 11 and connector 8.1 though.

So maybe it's a combination of resolve v18 and something else.

Low level log attached, thank you very much for looking into this
