REM libx264 compatible preset with scale support

REM === compression settings =======================================================================
SET "wset.out.video.rate=18"
	REM Crf factor: 0–51 for 8bit, 0–63 for 10bit, copy to copy the stream, leave empty to disable video. Values below 18 considered visualy lossless. Increasing the value +6 results in roughly half the rate/file size
SET "wset.out.audio.rate=320k"
	REM 64k, 96k, 128k, 256k, 320k, copy to copy the stream, leave empty to disable audio
SET "wset.out.video.scale.x="
	REM Leave empty to disable scaling. -1 is to scale proportionally, -2 to also keep it to multiple of 2 (use -2 for mp4)
SET "wset.out.video.scale.y="
	REM Leave empty to disable scaling. -1 is to scale proportionally, -2 to also keep it to multiple of 2 (use -2 for mp4)
SET "wset.out.video.scale.algo=lanczos"
	REM bilinear, bicubic, bicublin, gauss, sinc, lanczos, spline and more https://ffmpeg.org/ffmpeg-scaler.html
SET "wset.out.video.fps="
	REM Output framerate in Hz. 1 is to output 1 frame per second. Leave empty for no change. Set to negative value to override input framerate to the Abs(fps), this is useful for Gifs to presere all frames but change playback speed
SET "wset.out.format=.mp4"
SET "wset.out.video.codec=libx264"
	REM h264_nvenc, hevc_nvenc - CUDA h264, h265 encoders. h264_qsv, hevc_qsv - Intel Quick Sync h264, h265 encoders. libvpx, libvpx-vp9, vp9_qsv - vp8, vp9 codecs. libx264, libx265dnxhd, prores, prores_aw, prores_ks, rawvideo. Use "ffmpeg -ecncoders" command to list. Other codecs may have requirements not compatible with this preset
SET "wset.out.video.rate.control=cbr"
	REM Not used yet. libx264 supports: crf, qp, aq-mode x
SET "wset.out.video.sampling=yuv420p"
	REM libx264 supports: yuv420p, yuvj420p, yuv422p, yuvj422p, yuv444p, yuvj444p, nv12, nv16, nv21, yuv420p10le, yuv422p10le, yuv444p10le, nv20le, gray, gray10le
SET "wset.out.video.preset=veryslow"
	REM libx264 supports: medium, ultrafast, superfast, veryfast, faster, fast, slow, veryslow, placebo. This option also affects the rate
SET "wset.out.video.tune=film"
	REM libx264 supports: film, grain, animation, zerolatency, fastdecode, stillimage
SET "wset.out.video.keyframes=50"
	REM The output video will have keyframes each 50 frames, more keyframes (lower value) increases the output size
SET "wset.out.audio.codec=aac"
	REM aac, aac_mf, alac, flac, mp3_mf, opus, pcm_s16le, pcm_s24le, vorbis. Use "ffmpeg -ecncoders" command to list. Other codecs may have requirements not compatible with this preset
SET "wset.out.audio.sampling="
	REM Not used yet. aac supports: 96000 88200 64000 48000 44100 32000 24000 22050 16000 12000 11025 8000 7350
SET "wset.in.audio.file.extension="
	REM If the file extension is defined here (eg .wav), the audio file with the same name as the source's but with this extension will be added as audio to the output. Use uncompressed audio like wav for faster and more precise muxing
SET "wset.out.params=-hide_banner -stats"
SET "wset.out.sequence=0"

REM === color management settings ==================================================================
SET "wset.in.cm.space=bt709"
SET "wset.in.cm.primaries=bt709"
SET "wset.in.cm.transfer=bt709"
SET "wset.in.cm.range=tv"

SET "wset.out.cm.primaries=bt709"
SET "wset.out.cm.transfer=bt709"
SET "wset.out.cm.range=tv"
	REM Leave the cm.space empty to disable management for input/output. Color spaces: rgb, bt709, fcc, bt470bg, bt2020nc, bt2020c, smpte170m, smpte240m. Ranges: pc, tv, mpeg, jpeg. Primaries: bt709, bt470m, bt470bg, bt2020, film, smpte170m, smpte240m. Transforms: bt709, gamma22, gamma28, linear, log, log_sqrt, bt2020_10, bt2020_12, smpte170m, smpte240m.
