WebFeb 19, 2024 · Best settings for FFMpeg with NVENC. I'm using my FFMPEG with the suport of my GPU ( NVENC) to convert files from my satelite receiver (SD, mpeg2 .TS-Files) into h264 .mp4-files. ffmpeg -i "e:\input.ts" -vcodec h264_nvenc -preset slow -level 4.1 -qmin 10 -qmax 52 "e:\output.mp4". But the quality is not as good as expected. Webh264 (native) means that the detected codec of the input stream is H.264 and that ffmpeg will use its native (builtin) decoder to decode the stream. h264 (libx264) means that the codec of the output stream will be H.264 and that ffmpeg will use the libx264 encoder to generate this stream.

("MPEG-4 AVC" comes from the MPEG group, while "H.264" is the ITU-T standard, and which one you see depends on the program.) Note that ffmpeg/ffprobe already list the file as being h264 (avc) under "Input". Similarly, H.265 is the same thing as HEVC. WebMay 11, 2024 · May 11, 2024 at 14:13. 2.
