Is there any way to shoot against a Blue or Green Screen (sometimes called a Chroma Key) and then have the Blue or Green screen replaced with another image.

For example.

Sit someone in a wheelchair, a la Forest Gump, with Blue stockings pulled up to the knee. Then shoot the shot against a Blue screen.

Import the clip into PowerDirector and then underlay the image of the person in the wheelchair with an image of a room. Both the blue background and the blue stockings would be replaced with the image in the background making it appear as the the person in the wheel chair has no legs.

This would be typical of what a weather person uses on TV whwre the shot is against a Chroma Key background on to which a weather map is digitally imposed making it look as though they are standing in front of a weather map, which of course they are not.

Any help would be appreciated. ken

Do you have a screen yet?

Anyway, yes, PD can do this, easily, but you need to get the screen just right.
EVEN LIGHTING! Left, right, top, bottom, NO SHADOWS!
NO WRINKLES!
Watch your subject colors.
NO WRINKLES
EVEN LIGHTING! (see the theme here?)

Another suggestion for chromakey: use the Video Crop function to get rid of any weird shadows or poorly lit sections near the edges of the greenscreen.

If you look at my example, you might see I hid the worst part with the audience!

How do I place a pic over a green screen in PowerDirector ULTRA 14 I know its easy in Power Director Ultimate 14 but I have ULTRA and videos I have seen online only show the Ultimate version tutorial on how to do it. What is the step by step method?

Hi, Perry!

The method's the same whichever version you're using(by the way, as you're using PD14, you could've posted this in the PD14 forum, but were here no so we'll push onward).

It isn't so much putting your image over the "green screen" as such(I don't think that's what you meant initially) but after you've shot the video of your subject, as described in you opening post, it's a simple matter of choosing which background image(be it still or movie image), putting that on the main timeline, Video Track 1, then put the video of your subject on Video Track 2, then click on "Modify" the "Chroma-Key function" will then appear. Click on the "pippet"(eye-dropper) and it can then be dragged over to the image, click on the green background and it will disappear, leaving the background you wanted showing through. Hope that's of help.

Cheers!

Neil.
