How do I blur and follow the many faces in Premiere CS3?

I have a video in which I need more of a persons face the blur. I know how to blur a face using a mosaic filter, and track matte key but I can't get this to work for other faces in the same clip that are moving independently of the first person. I watched a lot of tutorials, but they all only show how to blur a face. Any help would be greatly appreciated.


I thank you.

Here's another way to do this, and in a way that I think is a little more tidy:

  1. Create a sequence called "MATTE" with as many tracks as sides you need to blur, plus one.
  2. Create an oval or face shape chart using the titration, Photoshop or other graphic software module. Don't forget that the oval is a pure white, with a transparent background.
  3. Remove your video clip on V1 and then drag an instance of the oval design on each of the remaining tracks.
  4. Position and animate each graphic oval over a face. If the people in the shot are not mobile, but the camera, you can animate the position of one of the ovals, then copy and paste the path to the rest of the oval graphic instances effect. Then, change the anchor point property to adjust the absolute position; the relative animation remains consistent.
  5. When you are finished animating the ovals, turn off the visibility of your video background on V1 layer.
  6. In your final movie, place another instance of your video clip on a track directly above the first. Drag the sequence MATTE BAC on the track above the clip duplicate. So if your original video clip on V1, V2 would be a copy, and the MATE nested sequence will be the V3.
  7. Apply the Filter Blur/mosaic and adjust the settings to your liking at the occurrence of clip on V2. Add the matte key track effect and set the matte V3 (or anywhere where your MAST is) and set the parameter of Composite using Alpha Matte. Immediately, you should see matte work on the track.
  8. You can also apply a blur (for example, blur accelerated) to the element nested MAST in order to soften the edges of the matte a bit. Adjust to your taste.
  9. If you need to adjust the position of one of the 'faces', go to a sequence of the MATE and tweak it. Changes will automatically appear in the final sequence.
