Re: [FCP-L] AJA QTtoDPX and FCP don't agree

Yes, the burn-in is beyond what is logged. I log a clip that is 25
frames long. FCP and QTpro display it as a 25 frame file that's
starts and ends on the expected frames. But when it's opened in
QTtoDPX and extracted to frames it is 48 frames long. No frames are
repeated. Each one is really really there. Every captured files has
1 to 3 frames on the head and 22 or 23 frames on the tail added beyond
what is logged.

Now this is all in a 23.976 FCP project. Actually more than one. I
have not tried any of these test in projects at different frame
rates. Maybe I'll try that tomorrow. But this is jacked up that I
can't just capture what I logged.
