Sony Vegas Pro 11.0 - rendering issues

October 2016


I want to edit a video in MainConcept AVC/AAC Internet HD 1080p format to .MP4 format, using the Sony Vegas Pro software. When I click Render, the rendering process begins and after 10 seconds this error message appears: "An error occurred while creating the media file. The cause of the error has not been be determined.


  • Click on "Render As"
  • Select a rendering template for "Main Concept AVC/AAC" (in your case the Internet 1080 HD)
  • Click on "Customize"
  • Under "Variable Bit Rate", you shall have the "Encoding Mode" section. Click on the scroll bar, and select "Render using CPU only."

Thanks to lechtimarseillais for this tip.
