Bit Rate setting work?

I don’t understand I keep setting the bit rate to 40/60/120 264/265 and it always creates a bad quality 6mbits compressed file, where am I wrong? does it only happen to me?

Use Proteus Fine Tune
Win 10

maybe try apple pro res 422 HQ?

are we talking about TVAI? because those numbers don’t exist in TVAI.

but anyway, if you select a higher number then the data clip actually has, it would output to the maximum bitrate the clip could offer. for example i set mines at 180, but most of my videos don’t pass the 30-50mbps.
