I tried

HandBrakeCLI -i file1.mkv -o output.mp4 -e nvenc_h264 --encopts="gpu=1"

where gpu=1 means my nVidia 3070. It'd stop about 2 seconds after it prints:

03:11:13 encavcodecInit: H.265 (Nvidia NVENC)
Encoding: task 1 of 1, 0.00%

I tried removing

--encopts="gpu=1"

and it didn't work. I tried changing to 0 and it didn't work. I also tried

--encopts="gpu=1;coder=auto"

in the docs here and it didn't work. I also tried gpu=any and it didn't work.

Can it be made to work at all? I saw an article saying it is about 5 times as fast as using the CPU to encode.

  • What is your end goal here? If it just is switching the format (container), and you don't really want to change the video, you could easily use ffmpeg instead. If you want to transcode the video to be visually lossless with a smaller file size, you should try Other Video Transcoding by Don Melton, it does a great job at that as it is made to "compress" ripped BluRays – DarkDiamond May 11 '22 at 17:06

HandBrakeCLI -i in.mkv -o out.mkv -e nvenc_h265

tried all your steps without result.

adding -e nvenc_h265 worked for me

  • so the only thing different is that you use -e nvenc_h265 instead of my -e nvenc_h264? I need to double check to confirm it is working – Stefanie Gauss May 15 '22 at 11:49
