Frage von Coldie:
Have all the other day in an American forum already posted (but will not help) ... Now I try my luck once. 
 Hi there, 
 i want to create video including light painting. It will not be a film made by stop motion (like this one 
 - great spot, but not what I'd like to achieve) 
 I want to get moving the actors in the background creating light paintings in the foreground. 
 There are two possibilities to do that: 
 1st Get the shots and the light-ANIMATE paintings tracked to the (useless) light / finger draw with the actors (like in this example 
  2nd Get the shots, extract the lights by adjusting the curves and add a simle 'echo-effect' - so they are REALLY painting with the light. (Like in this example 
 This method can be improved by not extracting the light source - but rather recording it with a second camera from the same angle and nearly closed blend. So you extract the light s.recording-time. 
 I prefer the second one - and that is the problem. 
 I dont want to animate the light paintings (except for the simple echo effect) - it always looks 'animated': D, but i also do want to loose my 3D space by restricting the light paintings to a 2D layer-recorded. 
 Here is s.example that impressed me:  
  In the second shot (the man in the restaurant) draws a circle (not animated - real light) ... 
 BUT the circle has kind of depth and fits to the camera movement even in Z-Space. Ok ... fitting to the camera could be achieved by a 3-Track with boujou or PFTrack, how is this DEPTH created by simply recording the light on but a 2D layer? 
 I add a picture to underline my question (front-and side-view):
