Motion Tracking Troubles
Someone please heeelllpppp!!!
Im trying to motion track an object that comes into frame so im doing it backwards but once it leave the frame the tracker doesn’t follow.
I tried doing what it tells you to do in total training and precomped the footage and increased the size by 400 pixels,..but when i go back and try..it still doesn’t leave the frame even tho theres plenty of offscreen room.
I have to get this video back in 2 weeks time and im no nearer to solving this problem.
anyone got any ideas? -

so if after it leaves the screen i track something else, wont that make the object jump at the change?..how do i do that without having realign the two frames with anchor point?

Hold down Alt ot Option when you reset that track point and the Attach Point stays put. It’s explained in detail here:

If the point you’re tracking is very close to the edge of the screen you might still have to place footage in a larger comp to be able to place the track points where you want them. The Feature and Search regions are restricted to the layer window’s size, so it’s impossible to set them on a point to close to the edge unless they’re in a larger comp. It sounds like you avoided that, thought you’d like to know.

I might be going off course here, but if all you needed to track was that one object (example… tracking a pinpoint lightsource in a shot in order to add effects to it), then after the object leaves the shot, it would be easier to just manually keyframe the rest of the information to get whatever you’re applying the motion-track to offscreen. Of course I don’t know the project you’re working on, so that might be completely unhelpful, haha.

It was an close up of a head on a stick.
The camera panned up from the bottom of the stick and stopped on the head at the top.
So although the tracked part left the screen the whole head is onscreen for another second or so.
although it was a cabbage with a cross drawn on it lol
Thanks for the help tho everyone..i’m off to watch that adobe tutorial,..I remember watching it a while ago, but obviously I wasn’t giving it my 100% attention 🙂
Peace,..over and outIGGY35
