Best effect for keying feathers
on Feb 21, 2013 at 4:54:38 pm

Hey all,
A little new to after effects and working on a comp with feathers. I need to key out the white behind a falling feathers video and would like a general direction on how to do that with the most accuracy. What keying effects are best for hair?
Thanks!

This is obviously much easier to do when the feather or hair is shoot in front of a well lit green or blue background. In this situation I would try the Luma Key or the Color Key. Hope this helps. Best of luck.

As Stephen said Luma key is good to key out white from the Footage but rarely gives fine results.

If you can upload a screenshot of your footage, I can create an example Project to show how you can use different keying effects to key any color.

Its almost impossible to key this kind footage. Sorry to say that but the feathers are merging with background too much. I have tried to key it just to give it a try but it seems very difficult. Didn't get any good result. Its like Occlusion pass from a 3D software package. From where have you got this footage?

Alternative:

If you want to create feathers in after effects , you can use Trapcode Particular Plugin and can create a very similar look just like the original footage.

May be someone else would be able to key this kind of footage.

Sorry, but you can't key that. The shot is monochromatic. The feathers are the same shades of gray as the shadows. I wouldn't hold out any hope for using Rotobrush, either. It would be a nightmare to rotoscope by hand.

It's time for Plan B for this footage. Sorry.

Can you take a still grab and cut out one of the feathers in Photoshop and then animate the feather falling from the sky?

Thank you everyone for your help, but I will probably have to come up with another plan.

Vishesh - thanks a lot for the experiment. Also great demo reel.

It's certainly possible to do what you seek in After Effects. Keylight is a very good keyer. So there are a few questions:

Does the person who shot the footage have a proven track record in lighting for chroma key?
What kind of camera was used to to shoot this footage?
In what codec and media container did this camera record the footage?
Is this test footage, or was it shot in the hopes that things would turn out for the best?

Dave,
I actually purchased the footage online so I don't know the answers to those questions. I did post a screenshot of the footage in this thread, so if that sparks any ideas please let me know!
Thanks for you help,
Lincoln
