It only happens with imported AE files, rendered as “native” M100i files. If M100 creates the file, “importing NTSC track filename.mov”, it’s fine. Media Digitized by M100 is fine.
Thanks for telling me what M100 expects. I checked my manuals before I posted and no mention of straight vs premultiplied channel.
What about Boris FX and Graffiti? Under the local project tab in graffiti I see preferences for straight, premult with white, premult with black, composite over black/white. Does this only affect the output of the graffiti file or does it also affect the compositing of the finished file to the timeline?
Thanks!
