I edited material from two cameras a few months ago. It was a theater performance. The sound was recorded on a separate device, and I clapped hands on-camera at the beginning of each video tape to help with the synchronization. After importing everything into Cinelerra I synchronized all of the video material to the sound track from the digital recorder. The video cameras did record sound, too, which helped with the synchronization (I could just match the waveforms), even if the sound from the cameras was not used. I think the clock speeds of the two cameras (of different make) and the digital recorder were close enough that it did not cause a systematic error in the synchronization. There were a couple of places where video frames got dropped during the importing (don't know why, probably a bad combination of camera/laptop/Linux firewire), and this did cause some headache. I added empty frames in places to bring the video tracks into sync and worked around those bits in editing. It was not too bad though, a few hours of work for 2 * 90 min of material. For the editing itself, I just used the fader controls. I.e. fade camera 1 out and camera 2 inbetween two frames to get a straight 'cut'. This was a little awkward compared to the normal editing operations (splice etc.) and prone to errors (accidentally leaving the fade control at some other value than 0 or 100%), but I got used to it quite quickly and I didn't think it was a big problem. Obviously, if there are more than 2 cameras, twiddling with the fader controls of lots of tracks becomes a major pain. The real synchronization problem was the music. I got the music on a CD that was used in the performance. The clock of the CD player at the theater was 0.6 % off (which is bad even for a cheap CD player) compared to everything else, so all of the music tracks had to be squeezed to get them to match the video.
