I am trying to blur out a specific area on a video but I can't figure out how to do it, I tried motion tracking but It keeps going off the area and also the area I am blurring moves off the screen and also moves quite fast.
How would I achieve this?
Motion tracking is going to be the best way to automate this. If you can't track it automatically, then you may need to manually keyframe some of the sections, where the feature you are tracking is offscreen. Either way, get the movement of the feature tracked and applied to a point layer.
Then you can use the Witness Protection effect and link it up with the point so it follows the feature. Or, create a new layer, add a mask to it to define the area you want to be blurred, so the rest of the layer is removed, then apply a blur, and parent it to the point so it moves with your feature.
