uncompressed recording?
I’ve been reading a couple of tutorials on how to prepare for green screening properly. I only have access to a DV camera, because a Betacam camera is out of my price range. The tutorial mentioned that the DV onboard compression creates artifacts around edges, and it occurred to me this morning…. what if I could capture before the video is compressed? I’m not sure if this will work, that’s why I’m posting here first. Here’s the procedure:
Set up camera with a computer/capture device in the immediate vicinity.
Hook up the video outputs to the capture card/device and begin capturing, so the camera should be simply sending what it’s seeing (with NO compression) to the video outs, right? It won’t work if the camera doesn’t output when it’s not in playback mode, and I’d test it but I’ve lent my camera out to a friend.Thanks.

A standard DV camera is going to have a svideo and composite output for video. Both are far inferior to the compressed, yet component digital output from the firewire or DV recording. In fact, your camera is most likely outputting the compressed DV image anyway, so that you don’t see a better image than you’re recording. The whole idea of monitoring is to see as closely as possible what is being recorded.
A betacam camera would possibly have a component video output that could be run into a component video card, which could capture uncompressed video to a sata raid.

Thank you for your reply.
Oh well, I thought it would be too easy a workaround to be good. I don’t know if it matters of not, but my camera does have have an S-Video connection available. I guess I’ll have to make it big first. That or not buy a car. It’s okay anyway, as another friend of mine has just found out the the broadcast and communications teacher at our school has a decent DV, but 3CCD, camera (I believe a Canon GL1 or GL2, can’t remember) that we will be able to use.
Thanks.

Yep. There’s 3 things that make for good green screen. The camera. DV can be done, but I think you’d need a 3ccd for sure. The lighting. Perhaps the most important part. If you don’t light and shoot it right, then you’re in trouble no matter what camera. And the software. FCP can do some good stuff with the built in color smooting and it’s green screen tools. But there are better plugin solutions out there designed specifically for DV footage.
