Hi! I've got quite a tricky shot that has a lot of people in the foreground moving around and a shaky camera, But I also have a stable camera taken at the same place that I can get a lot of information out of. I've seen that I can use the camera that has good tracking potential and use to help solve the one that is tricky. But I can't seem to get it to work so maybe I'm doing something wrong. I've tried tracking both shot, and connected the stable camera to input 2 in the camera solve. Then I switched to input 2 and sat that as "helper". Then I solve, It still get's pretty bad and I think I'm missing a part, shoudn't I be able to connect trackers between each input?
Maybe I need to use another node?
Alright, thanks for the info :) I only have movie clips, but when using a clip (i even have two clips, maybe I can use all of them? 🤯) do they help each other out to get an overall solve?
Also sorry for the late reply from me, I was away and then missed the reply
Hello Jonas, The Helper option is intended to be used when you have a few additional reference photos taken from different positions, loaded into a Photo Input node and then used to help build the initial solution for your main camera solve. To do this, you need to create a single User Track node, and each tracker created in that node must be tracked in your clip and also placed in your photos. This connects your tracking points between your primary clip and the reference photos.
There's an example in the Example Tree Layouts section of the documentation called "Camera Solve with Helper Photos" that shows a typical tree structure for this, which I've included here:
If you are using something other than Photos for your reference frames (i.e. you've got an entire clip) then you can still use the User Track node to connect trackers between your clips, but keep the Helper option disabled, and PFTrack will solve your additional cameras into the same coordinate space as the main camera.
