  cat <<USAGE
   Convert video files (using ffmpeg) to DaVinci Resolve compatible format
   -i / --input          File or directory
   -ie / --input_ext     Filter by input extension
   -o / --output         File or directory
   -ac / --audio_codec   Audio codec (default: pcm_s16le)
   -vc / --video_codec   Video codec (default: dnxhd)
   -vf / --video_format  Video format (default: none)
   -fmt / --pixel_format Pixel format (default: yuv422p)
   -bw / --bandwith      Bit rate for the encoder to use e.g. 120M
   -r / --rate           Rate (default: 30000/1001)
   -e / --format         Video format e.g. mov (normally autodetected)
   -f / --force          Overwrite existing target
   -v / --verbose        debugging output
Examples:
[dnxhd @ 0000000002be23a0] Frame size: 1920x1080p; bitrate: 115Mbps; pixel format: yuv422p; framerate: 24000/1001
 -vf format="scale=-1:1080,pad=1920:1080:(ow-iw)/2:0" -r 24000/1001 -bw 115M -fmt yuv422p
 -vf scale=1920x1080:flags=lanczos
 -vf scale=480:320,setdar=4:3
