Are you on an really old after effects version? like CS6?

in the last many years there has been a native DNxHR/DNxHD codec option under the Quicktime container format.

Unfortunately there is still no compressed alpha option in the Adobe native DNxHR/HD exporter, for that you need the old avid QT provided codec, but im not sure that at all works with the newest releases of AE anymore since all support for thirdparty QT codecs was removed.

I need to export DNxHD with alpha channels from Ae for import into Media Composer. Ae on my machine doesn’t show DNx anything in the export panel. I must have DNx codecs on my machine since I can export them from Media Composer, right? Any thoughts out there?

Many thanks. Lat at night here and been working all day so not too many brain cells are firing . . .
