Render time increasing indefinitely.
on Dec 4, 2019 at 12:21:26 pm

Hey Guys

I have just purchased Resolve Studio but and having some initial teething issues.

I am trying to export a H264 video with the following settings:

* Length: 2.16s
* Youtube
* MP4
* H.264
* Encoder: Nvidia
* 3840 x 2160
* Audio: linear PCM

The preview will plop along displaying what is currently being rendered, then randomly, it will decide to just go into "overdrive" mode, but not using any CPU then before.

I have allot of free hard drive space so i do not believe this is the issue.

I have version 16.1.1
1 CPU is running at 100% the other 11 are running at 3%
Memory is: 13gb used, 16gb are free
Swap is empty

Resolve uses GPU to accelerate when possible. The default render settings are to go as fast as possible so it will speed up and slow down depending on the processing required and the available resources. Codecs, denoising etc make the render speeds vary.

Thank you very much for getting back to me.

Currently my 2 minute clip has taken 79hours to render and has not moved from 4%.

If this was an error what else do you think it could be?

It's not going to render. Stop, reboot, try again.

Thanks again. I have actually tried this, a few times now.

I'm guessing its a fairly unique error then.

You must have a clip in the timeline that stops the render. You need to sort out what it is to try and fix it. Try rendering sections by marking In/Outs to identify the problem. This is something I have encounted in all NLEs

[Jamie Hutber] "I have just purchased Resolve Studio but and having some initial teething issues."
Which hardware (CPU, GPU, RAM, disk I/O speed)? What OS? What source material? What timeline resolution? What framerate? What format are you trying to render to? How does your drive rate with Blackmagic Speed Test?

I had uploaded these images with the thread. I did not realise that you needed to link them as below.

Sorry about that.

I didn't think Mint was a supported OS
