help with Keying..

[Kevin Camp]

the problem isn’t your keying as much as it your shot. from the looks of it, i don’t think your green is very close to a chroma green and even then it’s not lit very well. you’ll need to get much more even lighting on your background.

it looks like the foreground and background are lit with the same lights. you will need to light the background separately from the foreground.

additionally your subject is too close to the green screen, that will always make it hard to get a good key even with a good chroma (or rgb) green and good lighting.

there are some good tutorials here on keying, but i think you’ll want to find some basics on shooting a chroma wall shot.

I also read that keying footage shot with a DV camera is not easy and doesnt give good quality.. just my luck ! any software or tricks you can recommand for DV cams?

Hi there,

I’m also pretty new to AE, and might not be the best source of information, however I am getting better at green screen keying. I was running into the same problem with shadows and as Kevin said it’s mostly lighting. I think we might be using the same “green screen”. I found that shooting outside in daylight has given me great results with my DV cam. You can get a good key with DV cams, I do. As far as tutorials go, I would highly recommend videocopilot.net that’s where I got started. I try to screen record some of my attempts as a source of reference, in case I get stuck, I can send you a copy of my green screen “tutorial” if you like.

Thank you again Kevin !

[Kevin Camp]

you can find andrew kramer’s (the videocopilot) tutorials here too, and at his website. in addition, aharon robinowitz has a good tutorial on creating super tight junk mattes… don’t know what a super tight junk matte is? check out his tutorial, it can be really useful.

you can find both andrew and aharon in the ae forum as forum leaders.

I’ve read alot about DV footage and i understand better now as to why
my keying experience was horrible ! my problem isnt only my green screen lighting and spacing of the talent. I didn’t know i had to
de-interlace and de-artifact my DV footage first to get nice results…

question.. do i de-artifact before or after de-interlacing? or does the order matter at all?

[Kevin Camp]

if your interpret footage settings are correct, ae should do a descent job of deinterlacing your footage… you can check the interpret footage settings by selecting your footage in the project window, then, in the file menu select interpret footage>main… the separate fields option should be lower (ntsc dv, not sure about pal) and you can check the preserve edge quality.

you can then look into reducing artifacts, but you can get a key from dv, its just a little more work.
