Live Feed?
Is it possible to have a live feed going into Premiere Pro? We’re doing a greenscreen shoot and would like to be able to key things live. Is this possible?
If not, are there any recommendations on how to do this while staying within a reasonable budget?
Thanks,

Before you get started…
You can’t key live, you’ll have to do a test capture.
OnLOcation is actually the perfect companion for keying, in either DV, HDV, or DVC Pro, but you don’t own it…
I’m not sure what this project means to you, but keying DV in Premiere is probably going to be a nightmare. The only way I was ever able to get a professional looking key in DV was with Primatte, and that’s $700.00 🙁
If you insist in using DV and Premiere, you’ll need a waveform monitor.
Get your talent lighting first, add a light amber gel to the back light(for green screen spill). Then you’ll need cyc lights or fluorescents light on your screen. You could try work lights with diffusion. It’s not perfect, but if this is not a “client” project, it may just work fine.
The idea is to get a flat line at around 40-50 IRE’s.
Again, not sure what this project is going into. Make sure you do plenty of tests prior.

Vincent,
Thanks for your response. Actually, we do own CS3, though we have been so busy I haven’t had time to do the install.
Is OnLocation easy to use? Otherwise, I guess I could do Premiere for capture and then key in AE…

Well, if you have OnLocation, forget about Premiere for capture. First, Onlocation buffers the capture, that means no dropped frames (Unless you are using a system from the 90’s)
Everything is in there for you to monitor your shoot.
Use the waveform monitor to get a flat line at around 40-50 IREs as I mentionned earlier (With the camera framed on the green screen by itself). Move lights around to get those results. You can also use the Vectorscope, or the Spectra, which will tell you how “green” your screen is.
Adobe Ultra, which is part of the suite, will actually allow you to do live keying, though not capture I believe. It has a pretty good learning curve as well.
Good luck,
Vince

Actualy the help files for onlocation and ultra are good. Both programs are very easy to use. Onlocation will allow you to record knowing your camera settings are right. Use the tools in onlocation to set your camera up. Two very important settings when using a green screen are, use manual white balance and manual apature so the green screen color and brightness do not change during the video. Also turn your camera 90 deg to the right when shooting people standing. This will increase your resolution and not have to crop and waste the left and right of the video. Ultra has a setting to turn the video 90 deg just for this. You can thank Serious Magic for these programs as Adobe just bought that company last year.
