As currently I am recieving jobs from some broadcast companys as my clients, many of them will have certain requirment in bitrate.

 

Like for a lastest job that I recieved,

Video Codec: Mpeg2

Wrapper: MXF-OP1A

Bitrate: 50Mbps

Audio Bitrates: 384kbps

Yet I guess I didn't have the control for any of these on the panel (I know for H.264 mp4. you can set a target bitrate)

May I ask if there are any way to do or any 3rd-party plugin I can look into?
Thank you very much!

I just figure out the the bitrate is already 50Mbps after export but I'll still need the audio bitrate to be limited under 384kbps.

Thank you very much!

Export Settings:

Format: MXF OP1a

Preset: Custom

Video Codec: XDCAM HD 50 (4:2:2) - this is MPEG 2 at 50Mbps

When working with MXF OP1a Audio is uncompressed, you can choose 16 or 24 bit at 48000 Hz

and i found this:

24 bit, 48KHz 2,304 Kbps 288 KB

 

i think these settings are good to go for your required broadcast settings

I've tried 16bit sampling but the audio bitrate is still 768kbps.

24bit is even more like more than 1000kbps ._.
I was thinking like it's impossible to lower it down to 384 unless it's a compressed audio format.
