green screen shoot: HVX FW to PowerBook 15″ thru FCP to SATA — will this work?
i’m doing my first green screen shoot with my HVX. i plan on using the waveform and scopes in the capture mode of FCP and record to an external SATA via PCMCIA card. i will be shooting 1080 and/or 720…
i’ve done some quick tests, but this is the first big project with it.
thanks for your insight.

NO! Rent a proper waveform for Green Screen. Or better yet, rent one of them new fancy Panasonic Hd monitors with a waveform in it. The BT-LH 1700, 2600 or the little 900 all have built in waveforms that work. The cool thing is that you get an HD monitor along with it.

Jeremy’s right. The FCP waveform is certainly better than nothing. But after you’ve pulled your hair out for 2 weeks fixing bad green screen shots I think you’ll wish you had just ponied up a little more for a proper monitor….

Depends how complicated the screen is. If its just a “head” its not that big a deal.
If its near full body its more complicated. If they are standing on the screen then its hard.Bring a spot meter. After all we did green screen for years without waveforms in film.

[Leonard Levy] “Bring a spot meter. After all we did green screen for years without waveforms in film.”
Yeah, a spot meter/waveform. Tomato/tomahto. Not to say they are the same, but they are both measuring devices. Also, film isn’t exactly measured in IRE or millivolts. HD-SDI ports don’t come standard on a Bolex.

The waveform in fcp will work perfectly for judging your green screen lighting. just shoot the screen by itself to see that you have a flat line across the whole image at 40. I have the panasonic monitor as well and it is great having the built in WFM but there is no reason to not use the FCP WFM for checking your lighting.

I can’t get an accurate reading on my fcp scopes ever. I can’t trust them.

I’ve never had a problem.. are you talking a couple or ire off or 20 ?

Everytime I open them up, the waveform is pegged which I know is not true.
Once the footage is in, it’s more or less accurate, but even then, not really.

I’m still not sure what you mean when you say not accurate.. off by what factor ? Are you looking at it in the capture window or in the tools pulldown ? for a green screen all you really need to see is if is even or not.

I’m talking about live capture. open log and capture and hit the clip settings tab and the hit the video scopes button. The waveform is pegged way over 100 and the vectorscope is never on target off of bars.
I also highly disagree about having just an even background on a green screen, you should be hitting a 40-50 ire.
