I want to add several details to my previous message. I discovered this skipping frames problem during one-to-one training at my local Apple Store. The trainer did lots of trouble shooting, including adjusting FCE settings. I encouraged him to try copying my FCE project, and the DV file, to the store’s iMac on the countertop. The same skipping frames problem occurred in Final Cut Pro on that computer, adding to other evidence that my MacBook Pro and/or external hard drive (which I had brought to the store) are unlikely to be the source of the problem.
Afterwards, at home, I tried importing and watching several of my other DV files (all created with iMovie6’s export feature) in the FCE viewer, to determine whether the problem is limited to DV files created from analog Hi8 footage captured with the Digital8 camcorder. The same skipping frames problem occurs with DV files that were created from VHS footage captured with a Canopus ADVC110 and miniDV tapes captured with a Canon camcorder. (All of these DV files play fine in iMovie6 and with Quicktime.)
Next, I tried capturing miniDV tape footage directly into FCE for my first time. The skipping frames problem does not occur when playing that captured footage in FCE’s viewer. However, then I exported that footage to create a DV file using FCE’s export feature. The skipping frame occurs when importing and watching that DV file in FCE, suggesting to me that FCE and FCP’s import feature (which I know only references, not copies, the source) has a glitch.
