If unset, all input channels will be copied without mixing. If unset, all input channels will be used. In, set input channels to use from source stream. Swr (swresampler: default), soxr (libsoxr) audio-ignore-notrack-error ignore error when audio track is unfound.

f,-output-format set output format of output file. This requires use of avcuvid/avsw reader. input-format set input format of input file.

However, if your source material is lossless RGB and you want the absolutely best quality, use preset=lossless and uncomment SET videofilter=-pix_fmt yuv444p

I've added bunch of other settings there too but commented them out.

You can adjust it manually for optimal results: target framerate x 10 so for 60 fps -g 600. NVIDIA recommended using three b-frames (-b) in one of their pdfs for optimal quality (switch: -b 3). For AVC you can enable b frames with -b switch.

You can also play with -temporal-aq 1 switch (works for AVC) and -spatial_aq 1 switch (works for HEVC).

On top of that NVENC's constant quality rate mode works surprisingly well, quality wise. It's really great to see than NVENC supports this mode and on top of that it even supports lossless encoding and yuv444p format. rc constqp enables constant quality rate mode which in my opinion is really, really handy and I always use it over fixed bitrate modes. cq=number controls quality, lower number means better quality.

If you want lossless encoding use preset=lossless.

REM basically comments out the line so if you want to change encoder to hevc_nvenc (H.265/HEVC) add REM before SET encoder=h264_nvenc and remove REM for SET encoder=hevc_nvenc.

That script will automatically process every file in your Input folder and it will make Output folder for the new files.
