LIGHTS FOR GREEN SCEEN?

hello,

going to shoot some green screen with my HV30 this weekend and was wondering if 2 of these LED lights would be suitable:

are those only for the green screen? or talent and green screen? you'll probably not be able to light the green screen and talent with just those two. You may be able to light the green screen evenly enough to pull a semi-decent key with just those two. They're are probably pretty harsh for lighting talent in an interview.

Lighting for green screen is covered in many articles on the net. IIRC their was a decent one in the last month or so on ProVideoCoalition.com

Their are a number of threads about it here too.

Oh yea, Welcome!

yeah those are definitely only for the greenscreen. figured that if i was gonna shell out money for rentals, might as well try and find something that i could own and wouldnt use a lot of power and generate crazy heat.

thanks for the responses, folks!

If you get them, let us know how they work out. That's a pretty sweet deal.

I tried lighting greenscreen for XM2 with cheap lights = many hours wasted.
Then along came a HV30 & realisation what was wrong. I think you'll get good results with those lights either way Very Happy

They look handy & a good price too!

Yeah, DEFINITELY report back on how those work. Most LED lights seem to have a slight uptick in the green part of the spectrum, so they'd probably be pretty great for greenscreen. LEDs seem to really vary in quality, so if you got a pair of super-bright units for one hundred clams that seemed to have similar color temperatures, that's a great investment for The Rebel Type!

rebel hermanos,

i've decided not use the LED lights on this one. but i am going to get in touch with the manufacturer and ask how bright it is.

anyone have any experience shooting green screen, 24P on a HV30?

is it better to shoot 60i for keying HDV?

Yikes! Hell no.

I've used an HV20 for a lot of green screen work, it's all about brightly lit even screen, and moving the talent away from the screen 6-10 feet to reduce spill.
Keylight does bring up the artifacts inherent in HDV footage, I've been able to control that pretty much by crushing the blacks a tad in levels, or other creative use of CC. It varies shot to shot depending on lighting and colors. But with the HV20/30 make sure you have no gain.

And as Stu said and covers in the guide, interlace is horrible for keying and effects in general as you have horrible interlaced edges to deal with, really a pain the arse.

In case you still need ideas on setting up the shoot, Alex Lindsay just wrote a Green Screen overview too:

i called the manufacturer and the dude said that the LED lamp is comparable to a 250W halogen lamp.

thanks everyone for your input and links. i made many rookie mistakes on the green screen shoot, but it woulda been way worse if not for the rebels.

viva la rebellion!

I tried just for fun to do a green screen test in my basement last week, and it turned out pretty good. my screen was a 3.99 polarvide plaid from ikea, taped to the back wall. I lit it with, don't laugh please, cfl bulbs flimsy attached to stands on either side ( i didn't have enough lights to light both the test subject and the green screen) and lit the subject with one of those multi cfl softboxes that are dirt cheap on ebay. shot everything with an hv30. it keyed pretty well with minimal fiddling of the settings in ae, i'm pretty amazed.
