John Rofrano's tutorial on adding DNxHD to Sony Vegas Pro explains: Avid DNxHD can be downloaded free from Avid at this link: [Avid QuickTime Codecs LE 2.6.0] Once you have downloaded the installer you must run it to install the codecs. Make sure that Vegas Pro is not running when you perform the installation. Next you’ll need to create a render template in order to use it for output. This tutorial will show you how to create an Avid DNxHD template for rendering.
I do not understand how to get the download into Vegas. I am sure it is obvious to most people with computer skills but I can not get it to be added to the render options. Help!
