ffmpeg:encoding:h265:1-pass_target_bitrate
ffmpeg - Encoding - h265 - 1-pass target bitrate
A simple one-pass encode that tries to reach the specified bitrate at the end.
- This will likely lead to the wrong bitrate estimations for the video part.
- It is recommended to use a two-pass encoding mode if a certain target bitrate is required.
By setting -b:v and -b:a.
WARNING: Take care of the amounts used for the bitrate!
- -b:v is bitrate, so 10000 is actually 10 kbps. The setting should probably be 10000k in this case.
Example
ffmpeg -i input.mp4 -c:v libx265 -b:v 8M -b:a 320k output.mkv ffmpeg -i input.mp4 -c:v libx265 -b:v 8000k -b:a 320k output.mkv
NOTE:
- -b:v: Target bitrate for Video.
- -b:a: Target bitrate for Audio.
- Abbreviations can be used, like K for kBit/s and M for MBit/s.
