  1. with “ffmpeg -i input.mkv -s 444x250 -c:a copy -c:v h264_nvenc -pix_fmt yuv420p -preset p7 -tune ull -multipass fullres -rc_lookahead 32 -rc vbr -cq 29 -zerolatency 1 -gpu 0 output.mkv” is the CPU that scales the video, right? How If I want GPU make this? (My GPU “GK104” can only encode/decode h.264, not encode/decode h.265)

  2. thanks for two examples “If you want full gpu cuda decode and scale and encode”, anyway I can’t use them because my GPU card is too old :(

  3. where I can find info about the order of “-vf” and “-filter_complex” params ? Is this the only guide?

Thanks rroben27 for all!
