I'm new to AE, and am trying to do some motion tracking following this tutorial: https://library.creativecow.net/articles/devis_andrew/AE-Basics-53-Motion-Tracking-1/video -tutorial I linked in a clip (GoPro 4k as .mp4) from PP, created a Null layer and opened up the tracking panel, but the selection for my video file "GOPRO###" and "Null 1" are grayed out. I double clicked on the GOPRO### files in the timeline, which I'm assuming opened it in a new comp. From here I was able to complete the tracking, but then I have no clue on how to link this new comp back into premiere.
If anyone can tell my why all my motion source choices are grayed out, I would appreciate it.
Also, how would I add a .PNG file as the object that is following the tracking? Do I just add the .PNG as a layer, and set it's parent to the Null 1 layer?
When you double-clicked on the layer in the comp, you opened a LAYER window. That's the only window where tracking can take place. Once you have a good track, you APPLY it to a layer in the comp.
If I were you, I'd go over that tutorial a couple-three more times. Andrew spells things out pretty clearly in his tutorials.
