I have windows 10 64biy threadripper 1950x with 128gb of ddr4 2666mhz ram and a Nvidia 4070 with gpu cuda acceleration on and nvidia hardware encoding and decoding on. It took me 7min to render it before when I hadn't added 20 seconds of footage in the beginning. It's a 2min 30 second 4k project with footage from a Sony a7s3 now that I finished the beginning with some more broll and effects (the same effects that are in the rest of the video) it saying it's gonna take 2 hours to render. Am I missing something ? My cpu and gpu doesn't seem to be consistently used just a few spikes here and there.

I ended up turning maximum rendering quality and and render at maximum depth to off and it breezed through in like 20 min without getting stuck. Compared to the last render I did with those options on I can barely tell the difference in quality and the file sizes are not much different just off by 200 mb so I guess this will work for now

Hello @Thakur31724625loe3,

Thanks for writing in. Thanks for mentioning your system specs. Very helpful. Which flavor of footage are you working with? Specific formats do not do well with AMD CPUs, specifically H.264 or HEVC-based footage. For most editors, you may want to choose an intermediate codec to edit with, like ProRes or ProRes LT. That way, you can use your video preview files and leverage a 100% "smart rendering" workflow. Re-rendering for changes takes far less time than exporting an entirely new H.264 file. I hope the advice might help create a workflow that is really fast and of a very high quality. Let me know what you think.

 

Thanks,
Kevin

Thank you Kevin for your response and time, I failed to mention I had created proxies for everything I used cineform as the codex at 1280 by something because I heard that was good but do you think pro res is still the superior codec to use in this situation ?

Also I've had my timeline and play back both set to 1/4 resolution too to make it even faster but it still lags a bit on playback even when I've rendered timeline

I even took away all the effects and color correction and just tried to render the 4k video timeline by itself and it hangs at 5% when just yesterday it rendered everything out ( or exported I mean) within 7 min

Hi @Thakur31724625loe3 I don't see that you have assigned any in and out point for the segment you want to export, hence the software might show the estimate time for the overall timeline render. I hope you have Nvidia studio drivers installed in your system along with some basic Nvidia control panel settings configured, that will help you speed up the export. Hope this helps.

I have the in point at the beginning of project and out point when it ends sorry the picture isn't clear but what would you suggest for nvidia control panel settings I have it set to performance overall but in specific settings I don't know what's good and bad I tried YouTubing it but people have different settings like some enable anistrophic filtering anti aliasing and triple buffer and some don't.
