Join Mark Christiansen for an in-depth discussion in this video Plan for a track to be interrupted, part of After Effects Compositing: 6 Tracking and Stabilization.
- As you're aware, point tracking requires a point.…This is often a corner or other edge,…and the section of the couch that we're interested in…to cover up the action behind doesn't really have those.…Well, at least it doesn't seem to,…but in this lesson I'm going to show you…how many different candidates there…actually are for trackable points.…Now, if we just want to track the couch,…there's a common mistake that gets made,…and that is to just set the tracker…put it somewhere over, I don't know,…the couch, and start tracking.…
And, it's bouncing all over the place,…and the next step is to just simply give up.…But the issue is AfterEffects is…looking for contrast by default.…Now if we go into the options we can see…that by default it looks for luminance.…We can also track via RGB and saturation,…but luminance is the most visible and reliable.…We're looking for a pattern of light and dark…in this center square that is unique…from what appears in the outer square.…Pretty simple, right?…But if we don't give it any detail…
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.
