I filmed a lecture using an HVX shooting at NTSC-DV onto P2 cards.
As a second camera, I used a DVX shooting NTSC-DV onto long play miniDV tape.
I used the dreaded long play because the lecture was 1 hour 15, and I wanted no breaks. Also, the final delivery format is a fairly small online file (h.264, 427x240, 500kbps).
At the start of recording, I did a hand clap to sync the cameras in post. Now in post, I lined up the hand claps, and everything is nicely in sync at the beginning. But by the end, the clips are just about 1 exact frame out of sync.
Fair enough. I agree it's not a major issue, but I want to do a multiclip edit. What I did in the end was time-remap the clip (just stretch the whole thing by one frame), export, then re-import the adjusted clip which I'll now use for the multiclip edit.
