first thanks for writing me back
this was shot using the Sony PMW 350 on SxS cards. normally the camera was set to SD mode 50i 720 x 576. First I copied the folder from the SxS cards onto our archive disc (copy paste), then I used the transfer window in FCP to get the images into the project. This I think, is where the problem is because apparently I left the capture setting on XDCAM HD.
I will have to check tomorrow what the clip formats are.
Still I thought I could (simply) create another project, use the transfer window in FCP to install the archive footage, replace these new clips with the old ones, if the new clips have the same names.
is it possible?
