Hey there. I have a big problem. I’m trying to track these cool 3D elements to a phone I filmed. I watched a few tutorials, these:
Sean Dove Tutorial: https://www.youtube.com/watch?v=jbvVr1svCSw&t=203s
Digital Meat Tutorial: https://www.youtube.com/watch?v=uTyd378pP1I&t=1275s
Yellow Dog Tutorial: https://www.youtube.com/watch?v=QenuS_I0n-k
None of them deal w/how the camera is reconstructed for the scene with JUST the object tracker. They mention to motion track the scene first. That would be a good idea except I’m dealing with a static tripod shot filmed with a 105mm lens. There’s nothing to track that would help.
Anyway, I
- opened the motion tracker
- brought in my footage
- went to 2D tracking
- manually tracked the phone as best I could (didn’t put tracking markers on the phone - huge mistake). The track seemed alright.
- Then I brought in an object tracker, pasted my assigned tracking points, went to the ‘Reconstruction’ Tab, and hit ‘run 3D solver for object’ That seemed to work
BUT
It created a camera that was 17mm. NOT the 105mm I shot the scene with. I took off the protection tag that was on the solved camera, changed the focal length to 105, but then EVERYTHING was screwed up. My tracking points were all over the place.
I tried starting all over, setting the camera to 105mm BEFORE I brought in the object tracker. Same problem.
I don’t know what else to do! Please, PLEASE help. Somebody.
thank you
George
