[FFmpeg-user] FFmpeg default processing(invisible processing)

[Bouke / edit 'B]

Top posting, as my mail client does now allow for decent parsing, and I’m fed up with that.

My command to create ‘’proper” XDcam HD 50Mb, as required by the broadcasters here.
Read between the filenames, it does work.

/Applications/ffmpeg -hide_banner -threads 0 -i /Users/bouke/yadda.mov -f lavfi -i anullsrc=channel_layout=mono:sample_rate=48000 -map 0:0 -map 0:1 -map 0:1 -map 1:0 -map 1:0 -map 1:0 -map 1:0 -map 1:0 -map 1:0 -c:a pcm_s24le -ar 48000 -map_channel 0.1.0:0.1 -c:a pcm_s24le -ar 48000 -map_channel 0.1.1:0.2 -c:a pcm_s24le -map_channel 1.0.0:0.3 -c:a pcm_s24le -map_channel 1.0.0:0.4 -c:a pcm_s24le -map_channel 1.0.0:0.5 -c:a pcm_s24le -map_channel 1.0.0:0.6 -c:a pcm_s24le -map_channel 1.0.0:0.7 -c:a pcm_s24le -map_channel 1.0.0:0.8 -af volume=-11.4dB -vf setfield=tff,scale=1920x1080:flags=lanczos -r 25 -flags +ilme+ildct -top 1 -c:v mpeg2video -b:v 50000k -maxrate 50000k -bufsize 3835k -minrate 50000k -pix_fmt yuv422p -profile:v 0 -level:v 2 -t 26 -timecode 00:00:00:00 /Volumes/Data/magweg/Mars_Mars-Delight_26_1_19-12-2023_HD.mxf -y 

 Trust me, this command (besides audio parsing, depending on sources) has made thousands of broadcast compliant files over here, where XDCAM is also mandatory.
