Shooting on Blue Screen vs. Green Screen
I’m about to shoot a music video for compositing in AE.
I can shoot either on Green screen or a blue one,
when the blue screen is a bigger space which will allow me
to do more stuff (long walks, top shots etc).I’m shooting with a Sony DSR-450 (DV’s bummer for keying, I know)
Is there a big difference in the *keying* work I’ll have to do
between blue and green screen ?cheers

Hi,
DV handles colour sampling of green better than blue due to how the codec operates. So there is slightly more information in the green channel as opposed to the blue. I have however seen people get good keys out of blue…well, as good as you can get from DV.
In general it just seems green is more workable when it comes to a lot of “human” talent as green is usually absent. Blue is a little more common in clothing (try keying jeans with bad lighting). Keeping this in mind you can of course still make use of the blue space.
Best thing I suggest is to do a test key on both with the camera and see. What may take you a couple of hours may save you days in the end. It may even reveal some lighting problems you would later encounter etc.

Yeah in my experience green keys better than blue from a DV codec.
And as mentioned there is less green in peoples clothing generally, and i find that darker colours and black get a bit more noisy when doing a blue key.
Good luck -
Green is better in almost all digital acquisition, and blue is preferred if captured on film.
