Ouch I just got some HD footage, composite of CG and blueback which I have to put onto betacam tape. It's going on squeeze and letterbox. The original ratio is 1920*1080p at 23.98 psf, the card says the material is 30 seconds long. I found that when I imported it into FCP to export it to tape I'm lacking a couple of frames. I'm working in NTSC here, 29.97 fps, drop frame, SD. It's not a huge problem this time round, I can tack a couple of frames of still on the CI at the end. However I've a feeling we'll be running into these kinds of issues more and more as formats for production and performance diversify. So has anyone any idea where my frames have gone ? Did they disappear into the interlace, drop off in the drop frame, or did the guys at the other end just diddle me out of a couple of frames for a giggle to rub in the fact we are still in the stone age this end ? For the record, I did a rough version from a taped version first, and replacing the tape footage with the data footage I find the CI starts in the same place. Any ideas on the best way to deal with these various frame rates.
