Export set for 15Mbps, exported file is 30Mbps. What gives?

​@Kizzume:

Change the Bitrate Encoding pop-up menu from “VBR, 1-pass” to “VBR, 2-pass” where there’s a setting for Maximum Bitrate.

The forum says it needs more info.  What more information do you need?  I supplied the mediainfo files, and I explained that there ARE ways of making it work, but not variable bitrate using hardware encoding.

Anything?  It’s been over a week now.

Any updates on this?

Hi ​@Kizzume 
Thanks for including the screenshots.

One thing that stands out is that the bitrate value is being read from Windows File Properties. Before concluding that Premiere is ignoring the bitrate setting, I'd recommend checking the exported file with MediaInfo, as Windows Properties can sometimes report HEVC stream information differently than the encoder settings would suggest.

A few questions:

• Does MediaInfo report a similar ~29 Mbps average bitrate?
• Is the issue reproducible with both Hardware Encoding and Software Encoding?
• Does the same behavior occur when exporting H.264 instead of HEVC?
• If you switch from VBR 1 Pass to CBR, does the resulting bitrate still come out significantly above the target?

From the screenshots I can see:

• HEVC (H.265)
• Hardware Encoding (NVIDIA Codec)
• VBR 1 Pass
• Target Bitrate: 15 Mbps
• 3840x2160 at 60 fps

If MediaInfo confirms that the actual average video bitrate is nearly double the requested target, that would certainly be worth investigating further. If you can provide some sample files we can check them out for you as well.
