Precise Bitrate encoding w media encoder (h264 1920x1080, 25 fps no audio)

Hello everyone,

My client expects us to deliver all videos in Full HD with a bitrate between 10 Mbit/s and 11,5 Mbit/s.

Media encoder delivers different results for each clip - no matter what settings I use.

I have tried 11,0 Mbit/s CBR and 11 Mbit/s VBR with both sliders (Min and MAX) set to 11,0 Mbit/s).

I have also tried different profiles (Main and High) and levels.

The videos are pretty much the same all the time - a model in front of a grey background.

Some videos always come out with a too high bitrate, some always with a too low bitrate.

I use mediainfo an ffprobe to check the bitrate of the videos.

Does anyone have an idea how to fix thís and produce videos with an continous and precise bitrate?

best regards,

Martin
