Beer on green screen

[Jay Smith]

Hey guys, wondering if anyone has shot beer on green screen before? I'm thinking it should be too bad to pull a key but would love to hear from some folks who have been through this before. The pour will need to be placecd over solid colour background so shooting on trusty white isn't possible.

Thanks.

what colour is your background going to be?

Depends on the beer too. If it's a darker beer with more brown red in it you would probably be fine.
if it's in the yellow lager range I would consider shooting on the same colour as your destination background.

Hmmm... this could be a trickier pull than you think... and since you will likely need to recolor anyways, couldn't you dye the beer more red to help separate the liquid out, then recolor back to natural in post?

Isn't beer not always shot with a diffuse white light source in the background, with the light source/diffuser just silhouetting the glass?
As the glass (incl. fluid) will introduce a lot of refraction as well to the background information and produce reflections of the environment, any green-screen compositing approach will need a lot of love in VFX/Post.

(I do not drink beer nor shoot beer -- though)

The deal with good reflections in the glass or bottle is to back it with a gold card or foil.
The pour itself should have edge reflections from lighting and cards placed appropriately.

Using a clear or translucent object on a greenscreen stage that would be Refracting light(background changing color) seems like a problem.

could always run a test and see!

Try a test shooing with a white Background... and do a luminance key. Sounds silly, but worked for us once.

With color keys, its best to have the opposite colour to what your shooting behind the subject matter. So in this case, a blue would work fine, but make sure you don't get to much spill on the actual subject.

Another thing we did many years ago was put silver paper or foil on the back side of the glass to stop the key pushing through the liquid. if the glass was static.

I would shoot at higher shutter speeds, consult with a VFX guy and have him on the set. Also try to place the green screen further away to avoid colour spill.

Not silly. Mark is right. I feel the luminance key should be the logical way to go. White or Black.

I also agree with Mark as it worked out beautifully for us on Black BG for a Tequila shot with fire...
