media start & end offset on digitized clips
Don’t know if this subject has been already covered here.
It happens that when I digitize a clip the actual digitized media start and end differ from the TC data I originally put in the IN and OUT fields in the Log and Capture window.
The offset is generally 5 frame.
I have already checked the “offset” setup but I think it is correct. The time code is accurate when I compare TC on the tape and the relevant TC on the viewer).The above issue is very annoing when you digitize clips and you don’t have extra handles, as it happens when you digitize from instance from an EDL.
I am quite sure that the above issue was not present on FCP ver. 4.5.
My setup
FCP 5 on Pmac dual 2,7G, 2GB memory.
Kona 2
Sony MSW 2000 IMX VTR. -

You’re right, it wasn’t in 4.5. In 5.0 fcp has put in a frame offset option in the system setup. The default offset is 4 frames. It also happens when you set your in and out points, it stops 4 frames after you hit the O button. This was done to give you a handle for transitions. Reset the option, I think it’s in the capture tab, to O and try it again. you may need to set it and restart.

I don’t think this is the case, the above offset is to compensate the latency of devices like the AJA IO. For PCI devices like the Kona2 the value 0 (zero) gives you the perfect timing between the canvas and the actual video output.
The other offset present in FCP is and is the “capture offset” in the Capture Preset window. The value set here allows you when digitizing to perfectly match the timecode in order to compensate for the delay of the digitizer hardware. Kona2 has (if I remember well) a latency of 2,5 frames (PAL).
I underline that the problem I am experiencing is that the actual digitized media of each clip starts 5 frame later after with respect to the time set in the logged clip and ends 5 frame later. The fact that I am missimg 5 frames at the start of the clip is the opposite to the concept of an handle.
To be honest I think this is a Final Cut Pro bug.
