DSLR is it well suited for CHROMA KEY
on Sep 25, 2011 at 7:12:29 pm

Dear every one,

I am planning a green screen 30 sec commercial with lots of chroma keyed models. Its a kind of fashion spot.

I am thinking of buying the canon 60d with a prime lens, maybe 50 or 80mm.

Will dslr be good to do chroma keying? I plan to film on 1080p and edit into ntsc standard for the final edit as the broadcast will be ntsc.

I do know that the h264 codec is not the strongest to do post corrections so any one with some good tips on how to get the best results is welcome.

Any respond is appreciated.

Nope.. too heavily compressed

Bad for keying

Had to do a couple of bluescreen and greenscreen keying-jobs shot on DSLRs. It it possible, but I wouldn't call DSLRs "well suited" for keying...

Light your screen as evenly as possible, give your talent a rim-light and maybe do a bit of noise reduction on your material before keying...

But as Richard wrote, this heavily compressed material it can be quite a pain to pull good keys.

No! Been there done that! To much compression. Now, it can be done as I have and still do on occasion, but it takes a lot of unecessory tedious work to get a clean key. If you have a bunch of actors to key, rent a camera... It will pay for itself in post.

A camera that can record a 4:2:2 color space is more suited for keying. Many newer cameras, Sony EX-1R, etc. can record to an external recorder in 4:2:2.

Of course, the best camera won't really matter without proper lighting and software knowledge to pull a proper key.

Thanks for the reply,

I found a Sony ex1 camera. We have a big green screen to film models.

6 soft boxes.

As you recommended the Sony ex1, does it record real 1080p?

Would you recommend filming at 24 frames?

Anny other tips?

Looking forward to hearing from you,

Kind regerad,
