Unable to load DNxHD Quicktime in AVF Batch Exporter

[sfrankiel]

Other encoded quicktime (ProRes, MPEG-4, h.264) seem to work just fine, but DNxHD quicktime files won't load up in the app.

to the best of my knowledge, DNxHD files are not supported by AVFoundation, apple's official media playback framework, and the framework used by this batch exporter. a good rule of thumb is "if the current QuickTime Player tries to convert the file when you open it, AVFoundation doesn't support it".

please consider filing an enhancement request with apple about this- AVFoundation's lack of a plugin architecture is going to cause even more problems like this when QuickTime is officially removed from the OS.
