Track Motion "Apply" button is greyed out

[adamg60178595]

I've been using the track motion feature for a few weeks successfully. Now every time I try it will track a point through the entire clip but when it reaches the end the "Apply" button remains greyed out. Its possible my brain cells are playing up....

Workflow includes:

import mp4 video

create proxy to jpeg sequence (video)

run the track motion with 1 tracking point

tracking runs through all of the frames

then nothing

screen shot attached - any suggestions appreaciated!

Have you actually selected a target like another layer or a point effects control? Doesn't look like it, given that there is nothing else in your comp.

Ah, yes... I've realised my mistake. Thank you for the reply

what target should I select?

AE's tracker should default to the top layer, but its worth creating a null object and apply your tracked positions, scale and rotation to that.  You can then parent the layers you want to this null object.
