I believe that DV and DVCAM are the same animal, with DVCAM having a faster tape speed. Of course, now that I’ve said that, someone will come along with a correction 🙂
I used to use Serious Magic “Ultra” for keying DV, but I hated stepping out of my normal workflow in addition to using tons of disk space on 32-bit AVIs for my keyed clips. Then the AE 6 with Keylight came out, and I’ve never looked back. Don’t get me wrong…Ultra is amazing at what it does. But I’ve pulled some very nice keys from properly (and improperly) lit DV footage.
Just play around with it and you’ll get the hang of it. Just yesterday I picked up a project that had been on hold for a while, an instructional video with a little girl in front of animated vector cartoon animals. Having had more practice with Keylight I was able to improve dramatically on the Keylight settings from when I originally started the project. It just takes lots of experimenting.
