Camera Tracking In Videos?
I am trying to find out the name of the effect where the camera tracks a person’s body or face during a video, and also how I can do this with Sony Vegas Pro 9.
I have looked on YouTube a few time for any tutorials but cannot seem to find any useful ones and I do not know the correct name for the effect.
What is the name of the effect where the camera tracks a persons face or body (seems to pan around the video as it tracks the subject)
Thanks

I can think of at least two different effects that you are describing. Do you have an example?

Thanks 🙂
And well like when the actor moves across the shot – Say the camera is still, but the effect makes the camera appear to pan across the shot to follow the actor.
So basically to make the camera pan across the shot, even if the original video has the camera still in one position.
Is that of any help?

Also, now with the assistance of Boris Continumm Complete we can
get decent Motion Tracking.
Camera Tracking or MatchMoving is another thing.
Those are the terms Jay.Steve Rhoden

I think Jay is referring to the effect like that in The Matrix movies. It cannot be created solely in software with live actors.
A collection of still cameras (for example, 30) is set up around the object. At the moment when the action should freeze, all 30 cameras fire at once. The images they capture are played one after another to show the rotation, by placing them on the timeline at a few frames duration each. The duration determines the pace of the rotation.
In the movie “The Matrix,” the filmmakers also used an extremely sophisticated technique to accomplish much more advanced effects. Not only does the rotation occur, but the actor is also moving in slow motion during the rotation. At least five different special-effect techniques are combined to create the final image:
– A large number of still cameras capture the scene, but they fire sequentially around the actor rather than all at once.
– The cameras shoot the actor on a green-screen background (see How Blue Screens Work for details on this technique).
– The actor is wearing a wire suspended from the ceiling so that he can fall only part-way or appear to float in mid-air.
– Once the scene is shot, software similar to morphing software interpolates between the images to allow the slow-motion feel. The filmmaker can therefore slow down or speed up the action at will.
– Computer-generated backgrounds are then superimposed.My system specs: Intel i7 970, 12GB RAM, ASUS P6T, Vegas Pro 10e (x32/x64), Windows 7 x64 Ultimate, Vegas Production Assistant 1.0, VASST Ultimate S Pro 4.1, Neat Video Pro 2.6
