I was working on a clip wherein a title ( for example: Directed by someone ) should appear as drawn on the wall in the background.
To make everything more complicated the actor, after the title has appeared on the wall behind him, stands up and moves to the camera hiding the title appeared behind him.
I tried to track the wall in order to fix the title on hit but no success, so I thought to create a null object using it as the target of the motion track and connecting the pre-composed title to the null object thinking that he should have followed the wall, but no success... I really don't know what to do. The clip is not very shaky, but I couldn't come out...
Could you please help me.
The clip covers less than 15 seconds, there are no camera movements, the actor, at a certain point, stand up and cover the title (I used an animated mask) but the real problem is: how can I fix the title in order that it can follow the natural shaking of the camera?
Thank you for your kindness.
Tracking is your answer but it needs to be corner pin tracking. The other option is to use Mocha which ships with AE CS4 and CS5. Mocha is the better solution. There are a bunch of tutorials out there on the subject. Try a google search for AE Corner Pin Tracking. You can also watch a great set of tutorials from the makers of Mocha by clicking HERE
Thank you very much... I'll follow your suggestions as soon as possible.
