I'm having this strange problem when exporting a clip in M100 HD (10.1). Sometimes but not always, the exported clip have this codec -Xfer-. I guess it has something to do with alpha channel. The problem is that i can't reimport it in M100 without rerendered which is a pain with a 1 hour movie.
I work in version 10.1.4. I export audio & video. The problem appears periodically if i export by ref or self contained. I usually work with M100i codec but the problem appears the same way with m100 HD codec (always in SD). The problem seems to be connected to black clip : the same program exported without black clips at the beginning of the timeline has the right codec in apple i (either HD or M100i)
I've tried that once, and i think it worked. The problem is that i have film archives .mov that i would like to master to tape and their codec is -Xfermedia100- instead of i or HD. Another strange thing about these files is when i want to make a DVD video using Toast (the simpliest way i found), toast refuses to encode in mpeg-2 and always make a really bad mpeg-1 disc. Really strange. Can't figure out.
