I can't get video to play back for more than a second in Premiere Pro CS6. Is anyone else experiencing this problem? The files are from Canon DSLRs (T2i and 5D Mark III). These are just Quicktime files that play fine otherwise, and Adobe claims that DSLR files are natively supported in CS6. These files play fine in Final Cut Pro 7 and X, by the way. My MacBook Pro computer is 64bit compatible. This is stopping me from editing entirely. Solutions?
