best key you can. Assign the key to a keyer
with an empty keyer below it (Example:
chroma key on Key 2, with Key 1
unassigned).
Tip:
No attempt is made to resolve any shadows as they
are weak and indistinct. Raising the shadow sensitivity
would bring up other set errors.
2.
Set Key 1 type as Auto Select then select
Black as the Key Fill and the chroma key
source camera (in this example: Media Store
1) as the Key Alpha source. Turn on Key
Invert and leave the keyer in Normal Mode.
3.
Now adjust the key Clip and Gain until the
shadow area has the look you desire (you
can ignore the rest of the image as it will be
concealed by the chroma key above it).
4.
Now adjust Key Transparency for the most
realistic shadow look.
5.
Turn on the chroma key in Key 2 - Voila!
Great looking shadow from a poor image.
Good trick!
