After Effects 3D camera track, can't select track points

[shandygami]

Hi ~!

I have a question regarding camera tracking in After Effects. I tracked this scene/shot before and it worked fine, but I might have pressed a button that turned off the ability to select tracking points/hovering over them doesn't give me a target/bullseye either. (I am still able to view all the track points, just can't interact with it!) I tried it in a different project and it works fine, but each time i reopen my project the same thing keeps happening even after I retrack and solve it again.

Any tips? Let me know if my problem is understandable! appreciate the help, thanks

Aha. The scaling thing seemed to be the culprit, so I precomped the shot and tracked the comp.  Thanks!

As far as the error, now I'm getting 1.54 pixels which is better, though still not that great.  This might be due to lens distortion (I suspect this was a fairly wide lens), or maybe I should go through and delete the points that are reflections and on leaves waving around (though there's not much wind), or maybe it doesn't help that the camera is barely moving through space, and it's mostly just a pan.  But I can take it from here!  Many thanks.

try this trick - change from "Fixed Angle of View" to "specify Angle of View" and let Ae guess the lens. it helped me one time and reduced my error rate by about 0.50 pixels

I want to keep testing it.

Error went down from 1.54 to 1.51, so, a little improvement.  Huh.

Good news is that the track is looking good visually.

Thanks!

Great! learned something new today so thanks for that

I had the same issue with Red footage scaling, then precompd and solved it!   Thanks so much!

First u need to click on create Camera (highlighted-orange).

After the first step, you will get a camera layer on the timeline, and there you go!

Select any track point you wish to select.

I hope that's helpful!

Solved

None of the above worked for me.

Didn't work with me because my layer was reversed>

Precomed speed change and it worked like a charm

i had my comp at a different resolution and had scaled my layer down to match. This seemed to cause this error when it came to tracking. I could see my points but couldn't interact with them and my target wouldn't appear. I remade my comp at the same resolution as my video clip then tracked it. The target tool then appeared.

If you film with 4k you have to convert it to 1920/1080 then it works for me

this still doesnt work for me? ive been looking for 4 hours!

I had the same issue and all I needed to do was pre-compose (move all attributes) the layer that I was trying to track and it worked. If the layer is a different size than the composition... I seem to have problems selecting the track points.

If anyone is still having this issue in the 2022 version, the solutions here did not help me. The only thing that worked was turning off "render track points" under the Effects Controls, then turning it back on. This is the ONLY way I've been able to select track points. They're not selectable right after finishing the camera tracking, and the ability to select them goes away intermittently. So, just keep turning it off and on. Just another inexplicable quirk from Adobe 

Keep it weird, Adobe. I guess...

I have had the exact same issue for the past 2 days . I've watched 15 videos , and nothing seems to work . Layer controls are showing , active camera is on . I can see the tracking points , but no target appears .

Has anyone managed to solve your issue yet ?

Switching for the 2D tracker and going back to the 3D one works for me. I've been able to select a tracking point after that.

Nothing was working for me but i figured my footage was larger than my comp size. I couldn't tell this was the problem because the warning banner was waaayyyy out of frame for some reason. I saw it while accidentally zoom/scrolled out of the comp size. So here you go : you just have to pre-comp the footage, analyse again and voilà!

I solve this problem by doing this
1. My Export Video Frame Rate and Composition Frame Rate doing same and retry Traking
2. Select View>Show Layers Controls

3. 3D view popup "Active Camera"

Close After Effect and Retry After doing above step.
