Many people are working heavily with the MXF out of Canon rigs and doing fine. Some are having issues. A few seem to be dead in the water with that codec/wrapper. So I'd guess it's a combination of hardware & software configurations & interactions that Adobe hasn't completely nailed down. So ... you might want to snoop around here, though do remember, the ones who post most often and most ... decidedly ... will be those with problems, and those who are just working away ... don't post a lot.
Still, the more of you with those cams & footage posting here, the more they'll learn about the issues there and the better they'll be able to get this handled.
I'd recommend posting your entire hardware/software/processing info here ...
-OS/CPU/RAM/GPU/vRAM specific to the dot and with video driver listed also.
-Disc layout of programs, cache, projects, & footage ... and connections with any externals.
-ALL programs & plugins within those programs that touch the files, any effects. (Yea, I realize when you can't go more than 30 seconds "effects" are pretty nil ... )
-Camera/s used & original codecs/wrappers, frame rates & size.
All this can be of use to puzzling out what's going on. For some, just moving forward OR backwards in video driver has fixed it. For others something else has worked. And a certain number are simply ... frustrated.
Thanks Neil, I suppose I had hoped for a quick fix. As you say there just isn't one. I just find it incredible that something that would seem so fundamental would be such a problem.
I'll take your advice and put it all in the fouums and see where it takes me.
Thanks again Armand
Modern video programs are complex enough ... these Adobe ones add to that by trying their darndest to be able to work together on the same 'project' ... from PrPro to SpeedGrade to AfterEffects and Audition. Now, throw in the incredible variety of "capture" equipment, codecs & wrappers. Stir in completely differently coded operating systems, CPU/GPU, and other hardware concerns. What you've got is an amazing-that-anything-works result.
Adobe shoots far higher in this than anyone ... because of the intent to provide seamless forth & back, which no one else has. Some others stick the landing better on some of the details within a program, BUT ... going between NLE, grading, Fx, and sound involves completely different exports.
Pick your poison, so to speak. And as I noted, many Canon users or editors/colorists working with the output of same are doing fine. Some needed just a bit of help to get it going. I hope you'll be in that group.
