Clone tool tracking problem

[centelleoc43137807]

Hi,

I have footage from a film where I'm trying to clone out all the cuts and blood from an actor, which is fine and it looks great.

But the problem is the tracking part. I have 10 strokes, and I saw a tutorial online where I tracked a certain part of the footage, alt clicked the stroke position and linked it to the central tracking position, but if I do that to all 10 strokes they all get bundled together (obviously) in that one spot.

Is there a way I can track the footage so that all the strokes cover the face properly?

Thanks!

you'd need to do that trick with a different tracker and null for each clone stroke.

If each stroke is to be placed more or less with the same movement then you only need to offset the tracking data for each stroke by an amount equal to an Expression Point Control - of course, you may keyframe this Point Control for more precise adjustments, for each stroke. After pickwhipping, to create an Expression, you simply add the line below to the END of the Expression -

+ effect("Point Control")(1)

So, you'll get an Expression telling each stroke to follow the original tracking data but offset by an Expression Point Control. You will want to rename each Point Control to make it easier to identify them, individually, to make life easier for yourself should you require tweaking, later on.

I would stabilize the face first, then clone it, then reintroduce the motion. like demonstrated here:

centelleoc,

What did you end up doing? Let us know.

Thanks,
