First post ever on creative cow. I shot an event a few weeks ago on the 5D markiii. The footage was shot in 30fps 1920x1080. I transcoded the footage to Apple ProRes 422 and began editing in FCP 7. I had no problems when I played the footage back in FCP, however when watching it after I exported as quicktime there appears to be a flash or blimp whenever there is a cross-dissolve in the video. The video was rendered before exported and I was using the recommended codec to edit with so I would appreciate if anyone could guide me in the right direction to solving this problem.
