You have a scene with a person whose face have to be covered.
This scene is 2 minutes long (3000 frames). No problem since you have VirtualCompose!
The person is very nervous and struggle back and forth. No problem since you have VirtualCompose!
1. Set "Step" in "Control"-window to i.e. 100 (every 100. field will be marked by you).
2. Set all Points in the "Compose"-window (3000/100 = 30 Points a fast work) to struggler.
3. Press "Stretch len" in the "Operators"-window. Well done. VC have automatic interpolated all Fields.
Use this Timeline:
Background (Hintergrund) (Size:Start=End, Width/Height/Color at your own taste, Alpha 100%)
Scene with person
VirtualCompose
2.) To insert a result of other operator(s):
You have an object created with other operators (like Sphere, Scale and so on).
You would like to put it over a background scene with VC.
1. Put the background scene double (among one another) in a separate TimeLine.
2. Third is VC.
3. Edit the path.
4. Put VC in the destination TimeLine.
