Green Screen drop shadow

Post by devo_111111 »

So I have a speaker green screened on to some video with some text. I have drop shadow on the text, I want to have drop shadow on the person. I want to make my speaker into a silouette of himself, moving path it a bit over and down and then key it back into the video with the regular video on top.

The soft edge looks a bit cheezey and totally surrounds the head not just down to one side.

I have a spotlight filter shining on the background.

My imagination is fried right now and I can't figure this out.

You didn't say what version of MSPro you're using :P

1. import your greenscreened clip to Video2 (MSP8) or V1 (MSP7).

2. place a black color clip on Video1 (MSP8) or Va (MSP7) and set its duration to match that of the greenscreened clip.

3. apply the 'Bluescreen' key in the greenscreened clips 'Overlay Options', adjust the 'Similarity' to suit your eye & source then check the 'Invert overlay area' box.

POOF! You have your shadow-man with a greenscreen background. This is your dropshadow. Export it to a file.

4. load your projects background to Video1/Va, the dropshadow clip to Video2/V1 and your original bluescreened clip to Video3/V2. Apply 'Bluescreen' keys in each overlay clips 'Overlay Options' and adjust their 'Similarity' to 25-30 for starters.

5. apply a level 1 soft edge to the dropshadow clip and set its 'Blend/Opacity' and 'Transparency' to ~30. These can be changed to suit your needs/sources. Finally; apply a '2D Moving Path' to the dropshadow clip to shift its 'X/Y' location to your needs and you're done.

An alternative to rendering the dropshadow clip in MSPro 8 is to do steps 1-3 in a 2nd timeline then import that timeline to the 'Main Timeline' as a virtual clip. Assemble the background, virtual clip (the dropshadow) and original bluescreened clip on the 'Main Timeline', apply the 'Bluescreen' keys etc. as in 4 & 5 and you've saved some rendering time.

All its sources are built into MSPro8 (color clips, the greenscreen girl clip etc).

POOF! Is right. Thank you for the help.

To speed things up I just did it in another timeline then added it to the main.

Using the nested timeline thing is great.
