Same/similar capability for DNxHD in your ER ToolKit, on a Windows machine.?
AFAIK Should work more or less the same, but don’t take my word, try it yourself with the above video sample and let me know if importing the separate audio and video files into Cubando gives you a perfect sync.
Just note that DNxHD is a bit limited compered to the ProRes codec, and ProRes works perfectly well even on Windows without the need for the extra license that you need in Cubando to playback Avid DNxHD codecs.
