hello, i have a noob question. when i track a footage and it completes. i have all the points and i'm able to place a null/solid/text. but when i leave that layer that is tracked and then come back to it to place a new object. it starts to re-analize again. how do it get it to only analize it once. i'm currently using the latest version of AE 2022. i'm not sure if i'm missing a setting. but i see a lot of people only tracking it once, and they go back to the layer with the 3d camera and scroll and pick another "dot" to use and don't have to analize each time they choose that layer. hope my question makes sense. and any information i would truly appreciate it.

Without any specific info about your project, the footage you are using, tracker settings, your computer and so on nobody can tell you much. This is certainly not the intended behavior, but without more details nobody can even guess. From the interanl caches acting up to hardware acceleration problems this really could be anything.

thank you for your reply. i posted a quick 2 min video on youtube to show what i'm talking about. there you can see my settings, i been having this problem since i started doing after effects 3 years ago. with any version i have.  
link to video is :   https://www.youtube.com/watch?v=SPqQ0Cr_FMk  
i would appreciate any information. no one seems to know. perhaps there is a setting i have to enable/disable. but so far i can't figure it out. i hope anyone can help me with this. regarding you asking about the specs of my pc, the specs are good. i don't think that is the problem but if you must know here they are.

This is essentially not a 3D trackable shot, at least not in the AE realm and not without any static markers. I'm surprised it even solves at all, but that's likely a fluke. It starts over and over again because of course the patterns change all the time, even if just a single leaf is swaying in the wind and that invalidates the existing solve. You could potentially track individual segments and stitch together the resulting cameras, but more or less this is something way beyond AE. I would imagine that you could salvage it with manual tracker placement in SynthEyes or mocha, though, so at least give the latter a try and see if mochaAE is able to generate a stable ground plane for you. Otherwise this is really a case where you may need to plan a reshoot and place soem persistent red crosses on sticks throughout the scene for reference.
