Question

3D camera tracker just stops

I have the problem that the 3D camera tracker suddenly stops. I select the video track that the tracker should scan. Then suddenly at 17% it just stops. When I want to repeat it, it doesn't start at all. When I restart After Effects it stops again. But then sometimes at 12% and sometimes at 23%. There is no error message. It just stops.

I have tested several After Effects versions. Everywhere the same problem.

My system:
- Win11 Pro
- Asus TUF GAMING Z690-PLUS WIFI D4
- Intel Core i7-12700K
- 64GB DDR4 3600MhZ
- Samsung 970 Evo Plus NVMe PCIe M.2
- nVidia RTX3080 10G

Is it the same media each time? Can you give us the specs on the footage?

After Effects version: 23.2.1 (Build 3)

The current file 3840x2160 / 25FPS / 60Mbit
Stops at 13% (frame 162 of 1175) without an error message.

Only a section of 5 seconds was tried to be tracked.

 

So I could still work on the project I did it with Mocha AE which worked. However, I would like to use the 3D Tracker in certain situations.

Hi, sorry for the delay but I had a lot of work the last couple of days.

I think there's something up with that clip. I tried it and the analyzing process stopped at a certain percent each time. I tried shortening the clip so that the In point was past the spot where it failed but then it just sat at "Analyzing." I was thinking the codec was the issue so I transcoded it to ProRes LT, but it still failed in exactly the same spot.

 

Do you have other footage from that camera you can test? I'm worried there's a bad frame or something in there. You could also try the Mocha plugin instead of the 3D tracker; if you set it to track Scale it shodul work about the same. You're just looking to replace that flat panel with another graphic, right? Maybe the tracker is getting overhwhelmed with trying to track the guy too and the rest of the shot.


No problem and thanks a lot! This shows me that it must be the codec. With Mocha it worked fine. But I will do some tests with different video formats. Thanks a lot!
