This problem is a little difficult to describe, so be patient please.

the system is MAC OS X, Final cut pro 5, Blackmagic Multibridge Extreme with composite video out linked to the composite video in of sony monitor.

the project setting of fcp is DV pal with anamorphic option checked. what the monitor window of fcp shows is correct. but on the sony monitor ( set to 16:9 ratio), there's a chopping all around the frame, just like the overscan effect of a 4:3 frame. I have compared with the same video content without the anamorphic option checked in fcp5, and set sony monitor to 4:3 ratio, the same content of video is chopped. that's to say, if I output a anamorphic video, and set sony monitor to 4:3 ratio instead of 16:9, it looks the same as the video with 4:3 frame ratio--- the same content is chopped.


then I do another test, I output the anamorphic video to sony hvr-m10c digital tape recoder through dv-link, on it's lcd display, there's also a chopping. then let the recoder record some video and imported back into fcp5, the frame content is right, there's no chopping. It seems the datas are there always, but some are not displayed.

then here comes a conclusion---even for anamorphic video, there's overscan. can anyone confirm this? since I thought before that it should be like the 16:9 hdv without overscan.
