Failing export

I have a sizeable export that is failing right at the very end of the job. I can sit and watch it with Task Manager running so it’s not CPU, GPU or memory related and I don’t think it’s disk space (almost 1TB free). My question is how can I see the log? When the export fails the whole PC crashes and shuts down. Is the log saved somewhere that I can see it when the PC (Windows) is restarted?

Good grief! If the operating system is doing its job, an application should not be able to cause a computer crash. Does it always crash the computer? Or does it sometimes show “failed” in the export panel?

Is it possible that the export was actually successful? After the failure, I suggest that you go find the exported file and see if it works for you.

The export log is saved in a temp directory on your computer. If the computer is crashing, it is probably being cleaned up.

Thanks, Brian, I’ve tried this about three times now with different export profiles (it’s a 7-hour export so I leave it running overnight) and it always crashes. I once was there when it said 99% and 4 minutes to go when it crashed!

(It’s a cloud PC with spec - AMD EPYC 7543P 32-Core Processor 2.80 GHz; 28GB RAM and NVIDIA RTX AQ4500 with 20GB RAM)

The mp4 file looks to be about the right size but when I try to open it, however the player states it’s corrupt.

I thought as much.

I’m thinking I might split the project and try three or four separate exports and then join the resultant .mp4s…

That’s a good idea.

One theory I could offer is that as the export proceeds, the render process (Melt) incrementally takes more and more memory. You seemed confident that the memory is not being consumed. If that is the case, maybe there is one bit of bad memory and as the usage ticks up it eventually stumbles upon a bad section. A way to test that would be to run MemTest86 on the machine to ensure there are no spurious bad memory spots.
