VP16 - Rendering at lower bit rate than requested

Qoncussion wrote on 1/10/2019, 10:39 AM

I've been having an ongoing problem when Rendering a video in VP16. I am using: "MAGIX AVC/AAC MP4 > Custom Settings" to render. I set the Average bit rate to 28,000,000, and the Maximum to 32,000,000 - expecting a file that is around 28Mb/s. However, Vegas is only rendering the file at around 11Mb/s. Following are my settings. Can someone tell me how to get Vegas to render at the requested bit rate?

Using ^^ these settings - here are the file properties for the video file that was rendered - notice the Total bit rate at around 11.5Mb/s.

Any help would be appreciated!

It is encouraging to see a return of good investigational testing and data creation among a group of like-minded users.

Nice to be able to sit back, read, and learn for a change. Thanks

I share your sentiments. I posted a question to which I thought I may get one or two quick and dirty responses - but this really blossomed into an unexpected science experiment.

Thanks to all who participated!

I redid the VCE BruceUSA clip with a slightly higher data rate than was previously using VCE ver 3.1 laptop.

It moves it better relative to Nvenc etc, but there all very close really. So a small change in data rate moves the pecking order somewhat.

Opened one project (1080-50p), rendered with MAGIX AVC/AAC | Internet HD 1080p 50fps (AMD VCE), change average bitrate to 28 000 000, max bitrate to 50 000 000, everything else is default (AMD VCE, Default, VBR peak constrained) -- got 30.5 Mb/s video stream bitrate based on MediaInfo.

Opened another project (1080-60p), rendered with MAGIX AVC/AAC | Internet HD 1080p 50fps (AMD VCE), changed frame rate to 59.94, everything else is default (average bitrate 20 000 000, max 40 000 000, AMD VCE, Default, VBR peak constrained) -- got 20.6 Mb/s video stream bitrate based on MediaInfo.

So I do not have the issue (anyway I'm not using GPU accelerated encoding).
