Tracking and Scaling

[John Flynn]

I’m tracking footage and the points are a little bit inside of the actual area needing to be covered. Not at the actual corners Basically 90 percent of the area that needs to be covered is actually covered. I want scale up the footage to compensate but that throws the tracking off. Is there a fix?

Rather than resizing your footage layer, try reducing the size of the target. You could also make your four point tracking slightly smaller than the area you want to attach your target.
Good luck

I’m not sure what you mean. Basically I need to scale the footage up but the that throws off the tracking data.

The tracking dots were placed on colored surface but not all the way at the corners so when I track the footage to them I still see the colored solid around the edge of the footage. What I was thinking was to change I every keyframe porportionaly to compensate for the difference. But I was wondering if there was an easier way or a way to automate this, maybe with an expression…

Are you stablizing the footage for smoothness? if this is the case, the whole footage
will move around anchored to the point of stabilization and you will end up having gaps
in every direction. To resolve this, instead of resizing the footage directly, create a
null and parent the footage layer to the null and adjust the transformation on the null.
hope this is what you are looking for.

I’m not stabalizing, just tracking dots and applying them to the cornerpins of another layer.
