Removing Tracking Points from Footage
Okay…
So i am trying my hand at placing type in spaces, using footage and tracking the motion of the camera to then place the type and give it a realistic sense of being in the shot.
One idea I have is to do an upshot to a charachter sitting in the backseat of a car as it is moving, what i want is type to then be placed and look as if it is dangling from string attached to the ceiling of the car. So how would i get this type of movement? I considered attaching strings to the roof of the car so they dangle in the shot and place tracking points (bright stickers?) on the end of the strings, then in post production is it possible to track those points to get a realistic swing effect? Also how would i remove the tracking points? -

It would depend on the look you wanted to create. You could track the ceiling of the car and then have the text go along with it. If you are stuck (ho ho) on the idea of having the text jump about as though it is on strings, you could do what you suggest, then remove the string with cc wire removal. The thinner the string the better, obviously. Having said this, there are potentially some problems with this method: the jump of the string will be dependent upon whatever is on the end of the string, and if it’s not heavy then the text might appear too light, if that makes any sense. I would be more in favour of going with the former idea and forgettign the strings because it seems like a lot more work for difficult-to-predict results. If you want to get rid of the tracking references from your footage, you could use the paint tools.
