Join Mark Christiansen for an in-depth discussion in this video Continue motion offscreen, part of After Effects Compositing: 6 Tracking and Stabilization.
- The feature is tracked on the car,…and it just needs to be applied…to a null so the stripe…can follow the motion of the car.…And we need to solve the fact…that the track ends before the stripe leaves.…Now one thing that's hard to avoid…with motion tracks is actually…twirling down and looking at the key frames themselves.…So here we see, we've got some repeats.…So before I apply this track,…I'm going to get rid of the redundant…tracking frames, those were just holding…on that one frame, let's make sure…we're good at the other end.…
So we've got redundant frames on both ends.…And that looks to be the last good one.…Having done that, I'll twirl this up…and create a null object.…And we'll call it Stripe Track.…And I will set it over here…as a target.…
And I have this little bit hidden, so,…apply, I'll go back to X and Y, normal.…And then go ahead of the frame…where it's lined up more or less correctly,…I'll just parent the stripe to the track,…and notice that motion blur is on,…so as soon as I parented it,…it became blurry, which does match…
Here, Mark Christiansen shows how to use the five different After Effects trackers, customizing them to work best in the situations that motion graphics artists encounter most often. He covers the fundamentals, as well as opportunities to think outside the box, especially when an automated approach won't work.
