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
