ffmpeg - Conversions - Convert H264 to AV1 - libaom - Average Bitrate (ABR)

libaom-av1 offers a simple “Average Bitrate” or “Target Bitrate” mode.

  • In this mode, it will simply try to reach the specified bit rate on average, such as 2 MBit/s.

NOTE: Use this option only if file size and encoding time are more important factors than quality alone.

  • Otherwise, use one of the other rate control methods.

time ffmpeg -i a.mp4 -c:v libaom-av1 -b:v 2M -f mp4 out.mp4

returns:

...
real	106m2.063s
user	601m51.372s
sys	0m34.574s

NOTE:

  • Input test size: 75.5M
  • Output test size: 4.9M

NOTE: The bitrate limit by the -b:v where the bitrate MUST be non-zero.
