FIX: Windows Media Encoder 9 Series cannot encode constant bit rate (CBR) content at a rate that is higher than 20 Megabits per second (Mbps) (836546)


The information in this article applies to:

  • Microsoft Windows Media Encoder 9 Series

Notice

SYMPTOMS

When you use the Microsoft Windows Media Encoder 9 Series to encode constant bit rate (CBR) content at a rate that is higher than 20 megabits per second (Mbps), you receive the following error message:

Invalid profile: 0xC00D1BBF The video bit rate setting is not valid.

This problem does not occur with variable bit rate (VBR) encoding.

CAUSE

This problem occurs because a limit that was set in earlier versions of the encoder does not permit you to encode CBR content at a rate that is higher than 20 Mbps.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.

MORE INFORMATION

The hotfix in this article resolves the problem for the command line encoding utility. The encoder user interface (UI) is still limited to 20 Mbps for CBR content.

For more information about how to use the command line script, see the Windows Media Encoder 9 Series Help documentation.

Steps to reproduce the behavior

To reproduce the behavior before you apply the hotfix, run the following command: 
cscript.exe wmcmd.vbs -input d:\temp\infile.avi -output d:\temp\outfile.wmv -a_setting 128_44_2 -v_mode 0 -v_bitrate 24000000 -v_quality 97
