Occasionally I hear an After Effects user asking how they can read a DPX that doesn't conform to AE's expectation of a 10-bit RGB file. The DPX spec allows for 8, 10, 12, or 16-bit images, and also supports alpha channels. Since even After Effects CS6 can't read these files, I decided enough was enough and pushed out a free plug-in, which I'm calling DPX Plus. Fortunately this was a pretty easy project thanks to Patrick Palmer's open source DPX library.
When DPX Plus is installed, it becomes AE's default DPX reader, which is not ideal. I'd rather you had to go out of the way to use DPX Plus, but as it stands you have to manually designate AE's internal reader if you don't want your project to rely on a 3rd party plug-in. If you're worried about this, perhaps just use DPX Plus to convert your DPXs to 16-bit PNG or some other format AE can read natively and then remove the plug-in when done.
Update: DPX Plus now includes Photoshop and Premiere Pro plug-ins as well.
Update 2: DPX Plus can now write DPX files out of Premiere and After Effects.
Update 3: After Effects CC is now shipping with read support for all the DPX varieties that DPX Plus can read. It can also write specific varieties of 8, 10, 12, and 16-bit DPX. Premiere Pro CC can read 16-bit DPX too.
