I imported a few .tga image sequences and played them back with no problem. Went to render them out to Quicktime ProRes 4444 and I keep getting this error. Forces to restart AE.
Could simply be one more undiscovered CS6 bug. No idea. Haven't tested it and have long stopped using Targa files... Always udse 16birt TIFFs/ PSDs or EXR files from C4D...
