I’ve rendered 400 videos with the settings you see in the pictures, but ever since updating to the latest version, “h264_nvenc” no longer renders the videos in 4K. I can only output videos that are low quality at 5mb or less. If I change to the codec to “libvpx-vp9” I can achieve what I used to, but it takes 1-3 hours longer to render. How can I fix this?
Hey Austin, thanks for the response. I have a 4090 and I’ve done hundreds of videos at these settings on this hardware with no issues, but I will try your suggestion and report back.
It is working for me with a RTX 4070 with Shotcut 24.04 on Windows including at 100%, which is automatic and not lossless! BTW, this automatic mode is an NVENC thing (decision-making), and I find the quality to be quite poor.
For lossless, see
But also, that creates a very large file when compared with x264 lossless; I discourage usage of h264_nvenc for lossless.
Use 75%, the quality will be very high without massive file sizes.
I just tested the quality with Properties > menu > Measure Video Quality, and Export > Codec > 75% gave a VMAF score of 99.995%. And this was with very shaky, fast moving, high details (FPV motorcycle ride surrounded by trees moving head to look around on a GoPro with stabilization turned off). To understand further, you can search and learn more about “lossy video compression” and the “VMAF” video quality metric.
Here is a heavily down-scaled and compressed version of that footage I described
Why you are using 100% quality settings? On my GTX1660TI I get out very good results with 65% quality settings. Everything above my hw encoder seems to does not like it (huge speed drop…).
Probably because he has a RTX 4090
I don’t know but people say it’s the best in the market right now, and also the most expensive consumer GPU
I would surely set everything to 100% if I have the best consumer GPU on earth, even though it’s nonsense because I would get almost only 1% difference by setting it to 80%
Because I burned my money on that piece of sweet cookies
100% means preserving all color and texture data which does not make sense.
shutcut leader’s suggestion 75% quality is also extreme high and there will be a hardly noticeable difference in the result (I am sure I will not see any difference)
