PC stops rendering video based on photos

Hi all,

I'm pretty new to Davinci Resolve (15 beta 6) but have used it for some simple video editing with success.

Now I have the following problem: When I try to deliver a video, DR stops rendering after approx 60-80%.

My video consists of 17280 still images (4000 x 3000 pixels) - one picture each 5th seconds for 24 hrs. On top of that I have added 24 texts: 00:00 to 23:00.

I have tried delivering to "Youtube" using .mp4 format in different resolutions, but they all stops between 60-80% of rendering. I get no error messages - it just stops. I have had it running for 8 hrs AFTER it seemed to stop to see if it was just slow - but no - it had stopped.

I have a pc with an i5-4440 CPU @ 3.1 GHz with 16 GB RAM running on Windows 10 Pro 64 bit version.
My GPU is a GeForce GTX 960 with 12 GB ram.

Please ask me what kind of details you need from me, if you are willing to help me out .

Could it be your hard drive filled up?

AFAIK that GPU has a maximum of 4GB VRAM, not 12, and often comes with only 2.
What is your timeline resolution?

No, this data drive still has 460 gb left. Thanks for asking.

Ah... you are probably right! The System Information provided by Nvidia says: "Total available graphics memory: 10209 mb" and "Dedicated video memory: 2048 MB GDDR 5".

My timeline resolution is: 1080 x 1080 @ 24 FPS.

Try dropping your render speed a notch or two. That works for me when renders stop.

Have finally had the time to try. Still not working. Apart from "Maximum" I've tried 100, 75 and 50.

What I see in the Task Manager is that it has opened 9 Console Window Host, 1 DaVinciPanelDeamon.exe, 8 DPDecoder.exe, 1 FustionScript services for Fusion and 1 DaVinci Resolve. The last one does not respond - but uses about 30% of my memory and 9 gb of ram (approx 75%).

When it hangs it uses 0% of the GPU.

Another workaround:
- check Playback -> Render Cache -> Smart
- wait for caching (start Play from the start to the end, wait for the blue line to appear)
- on Delivery page, Video tab, Advanced Settings — check Use render cached images

Result (probably) — very fast (faster then realtime) rendering without stops.

you overclocked your gpu?

Your GPU might be choking on those stills.

No - I don’t dare overclocking!

Will give it a go. Sounds like a good solution to me!

Will revert with result if it works or not.

Nope - that didn't work either!

Okay, I ended up exporting the final movie a little different. It's not optimal but it works.

Step 1:
I rendered two movies, 6 minutes each. Fun fact: I had to export them one at a time. If I exported them in the same "batch", movie number 2 failed.
Step 2:
I created a new project, imported the two previous movies and re-rendered them. It worked!

It's not optimal in several ways: It seems like an unnecessary step to make two temporary files. And in my example, I exported as MP4 (which has compression) both during the export of temporary files and the final file. So there is a loss of quality. For this movie it is okay, but if I have to do it again, I will see if I can find a lossless export for the temporary files.

Thank you for all your answers and suggestions!
