I have long been trying to find out how the effect goes by one person in one of several video without the need for a mix that is impressive and the images are transparent. does it only with chroma key (green screen, blue)? as an example of the link:
Antwort von Stefan:
With Sony Vegas Video, I can not serve. But perhaps you can place the basic principle of reality itself ...
The basic principle is simple. You need a video of the scene with the Darsteller1 and a video with the Darsteller2. Background of both scenes should be the same (camera on tripod, preferably the same illumination and camera settings).
Video1 is your basic track. Moreover, a mask (Engl. matte), the only Darsteller2 from Video2 shows. The masked Video2 is combined with Video1 to Endvideo with the two performers. The mask is a SW-Picture with black areas and white areas. From the Video2 is Video1 over what's in the mask is white (normal setting).
Normally, moving the Darsteller2 in Video2. That's why you need a moving mask synonymous (Engl. traveling matte).
By keying can auto moving such masks can be generated. The decision criterion for the hidden part of what can be heard in various ways to be as color, brightness, contrast to another picture ...
If you are not keying, can / should you have a mask of selbstgezeichnete hand move, or even a new mask to use when the actor has moved.
The intricacies of the procedure will come later. These relate to the edge of the mask (smooth transitions) and the Kopiermodi of Video2 after Video2 (Ebenenmodi). As a self-experiment worth watching and how does what.

Antwort von Axel:
As Stefan writes, the camera on a tripod stand. In the clip, but it moves constantly. Apparently, the Motion Control, a programmed, of a calculator-controlled camera movement, the synonymous after 50 repetitions produced no deviation (unaffordable). I guess you have only the empty bar up, then for the following recordings stand-ins s.die positions, later George s.denen or Mary should be, but I consider that each a piece of paper on the chest was: " Stand-In for Take 23 ". This is probably necessary, so that people do not jostle or an arm by another drifts, a meticulous timing issue. Whether the current incarnation of then painstakingly hand was exempted by a Differenzkey (likely) or by a behind the singer mitwandernden Green Screen, na ... If you can not imagine, what with motion control is concerned, look at the making of Hollow Man Of that there there will be very well shown.
Antwort von Marco:
Depending on the objective and the source material, you can do that in Vegas with a primitive mask with the cookie cutter, with an image shift with Track Motion, with a self-subscribed mask with Pan / Crop or with Chroma Keying make (maybe still synonymous with a differential -keying). Chroma keying is necessary in the post is probably the easiest solution. About the Chromakeying you can find in the tutorial area of www.vegasvideo.de.
