Sorry for this bombardment of [probably stupid] questions this week, I'm
still getting to grips with all the jitter objects and the differences from
GEM that I used to use in PD.
What would be people's recommended methods to achieve the following be:
I'm trying to process live footage from a webcam (that is being keyed over
another video). I've already got it so that the background is removed
leaving only people in front of the camera. I now want to create an effect
where when people move around in front of the camera it leaves a trail of
images (say 500ms cam grabs) following them from where they were standing
before, that then take a set period of time to fade away. But the longer
they stand in one place, after they move the longer it takes for the images
to fade away.
I hope that is clear. It's difficult keeping that concise when there is such
a vivid image in my head of how this should look!
Any tips from you pros?! ;)
