The encoding speed is over 50% higher than with using the CPU. I have used your workflow and changed some options to get the output as required. Thanks for letting me know and saving my time with unsuccessfull compiling trials. I didn't recognize any I didn't know that FFAStrans comes with a compiled nvenc ffmpeg version. Thanks a lot for your help I have excatly done what you said and tried OpenCL but it didnt increase the speed of my workflow. c:v h264_nvenc -preset slow -c:a libfdk_aac -b:a 384kĪnd as container pick mkv, save and see whether it works or not. Anyway, try to use a custom ffmpeg node in FFAStrans and use: The two most common places to find builds for Windows are: and but I don't know whether they have it enabled at compilation time or not, but just give it a shot, try them and you'll find out.īy the way, I'm not even sure whether this is allowed in the current builds shipped with FFAStrans as I've never tried 'cause I'm not interested in GPU Encoding but only on GPU filtering. If you have x264 nodes, you can just write "opencl" in the Custom x264 options (ffmpeg x264 params) and see if it helps.Ībout NVEnc in general, you can try to see if you can find some builds that have already been compiled with it by using:įfmpeg.exe -i "my_input.mxf" -c:v h264_nvenc -preset slow -y "my_output.mkv"Īnd then all the parameter you can configure with it. Before you try with NVEnc, can you try to see if using OpenCL increases the performance of your workflows?
