Several readers have confirmed that many ADVC (advanced digital video converter) devices consistently drop some frames of converted video.
Users of the ADVC 100 (manufactured by Canopus) report that QuickTime 6.5 with Mac OS X 10.2.8 and and Final Cut Pro 4.1 works well, without lost frames, but QuickTime 6.5 with Mac OS X 10.3.1 or 10.3.2 and Final Cut Pro 4.1 skips frames.
There are also separate reports of problems using the "Capture Now" function in Final Cut Pro 4.1 to deliver digital video to external FireWire drives. The dropping of frames is obvious, as file sizes of captured video segments will be much smaller than normal.
If you're having problems with dropped frames, please drop us a line at firstname.lastname@example.org.
