keying tool

Use Keylight.

[Andrew Shanks]

Keylight should work fine, DVCPro HD is a little noisey but still gives a great key (have done a number of shows that have used varicam).
As with any keying job, the one click key is hardly ever likely to work, I mean you can get okay results if things are well lit and your subject isn’t anything too complicated (with motion blur, hair, etc). Build a proceedural matte (there is a tutorial Barend did here ages ago, …I’ll try and find the link and pop it below), where you build up an edge matte, a vore matte and a garbage matte, …you then apply that to your image and use your own form of spill supression (be it using the built in spill supressor plugin or using saturation (to desat blue channels only), curves or whatever. A bit of light wrap or edge blending can put the finishing touch to the comp.
If you really want to get heavy in the keying dept, get Shake, but there is no reason why you shouldn’t be okay with keylight in AE. 🙂

Here’s Borend’d article on keylight (worth a read)

and here is his proceedural matte tutorial

Although the thoughts behind that article are still valid, I’ve refined my workflow somewhat over the years – and the addition of Keylight to today’s toolset really helps.

I’ve done extensive keying on DVCProHD material over the last year and here’s what I do BEFORE I key.

Drag the footage into a comp. Apply Deartifactor from the Key Correct Pro set. Highly recommended. It really is a world of difference.

Add an adjustment layer. Apply Remove Grain. If you apply the plugin directly to the layer it’ll bypass the deartifactor.

Usually I set noise removal to around 0.5 and sometimes I add a little bit of temporal filtering if the material is noisy.

Drag this comp into a new one and proceed as you would normally – using this comp as your source footage.
