I realized that its impossible to use custom settings at this time because NVENC doesn’t work (log reports NVENC has been disabled and proceeds using CPU only)
What to do? Sit down and cry? I wasn’t using Shotcut for a while, but I remember rendering using NVENC never tickled my 1050Ti (never reached 20% processing). However, the current situation is much worse. Jobs are taking about three times longer to complete.
What happened?
I am also accepting tips and tricks to optimize my options and try to reduce rendering time without compromising quality.
Do you have the latest nvidia drivers and can you check your gpu using gpu-z as well? windows may not show utilization of the NVENC block properly inside task manager. You’re still going to see measurable cpu usage as well since the cpu has to do work keeping the gpu “fed” for video encode.
The log suggests some timestamp issues in your source file. You might consider replacing it with an intermediate I-frame format
What about the project itself ? What does it consist of roughly? e.g. If you’re using some CPU heavy filters, or poorly multithreaded filters , it might be a bottleneck for the “GPU” encoder
This happened to me awhile back, with my RTX 2080. IIRC I think there was something corrupted in my Windows 10. Luckily I have a clonezilla backup of my Windows 10, I installed that and installed Shotcut and all was good. I too use HEVC all the time. Hope that helps
to me this thread seems to be interested because I have an issue with GPU rendering, too. But in my case, I have as a result from export only a black screen with sound.
I’ve watched videos, tried ´settings, but still the same: black screen with sound.
Though it seems that the export runs normal, seen from the time it needs.
I have a GTX 1060 6GB…
Any suggestions?
We have code to automatically change B frames to 0 when you select HEVC with NVENC and AMD AMF hardware encoders. However, we also let one change it because I do not have all their hardware, and new hardware and drivers could add support without me knowing.
The only thing I can think of is may be something is corrupted with your windows OS. As this happened to me once and all I did is reload a clonezilla backup. If you have a clonezilla backup of your windows OS, try loading that to see if it’s any better. If you’re going to do a clean install of your windows OS, I highly recommend to try and learn how to use clonezilla.
Currently, no, no chance…
I’m still using Win-7 and Linux Mint 18.1, and next year I want to upgrade my computer, new CPU (maybe AMD, currently Intel i3-6100), new Motherboard, maybe new RAM (faster), and of course a M2 SSD, and then “of course” Win-10.
But I remember it!
strange, strange, strange. Where to begin…
Normally, if you have exported, you will have a picture in the new icon, and that I didn’t had. And the issue is, when I play a sound file in the SMPlayer, the whole position settings are gone. So, my idea was to test the exported file in a browser…
No it comes…
The browser, in that case, is Firefox, and it shows a black screen while playback. So I thought the export was incorrect (or so). (And, yes, that happend to me a while ago…)
But just, I hadn’t a thought about it, I double clicked on a mp4 icon with no picture and, wonder, SMPlayer shows a normal video file.
At that point raises the question: Why do I have sometimes not a picture in a new, exported, video file?
And at that point, I will try again with your settings with GPU rendering…
I just gave it again a try with GPU rendering…, but no, no video (to see), only sound. Played back with VLC. And the time to export the video, was ~ similar, as with not GPU.
But NVENC should work, because I used it earlier, as I record my flights from my flight simulator, where I used that NVIDIA recording…
