Hi! So I’m relatively new to Blender, but I’ve decided to take on camera tracking. I have a very low solve error, but for some reason, Blender’s camera is not moving at all correctly to fit my model into the scene. I’ve attached the file I’m working on below:
Can you post a link to the footage? Having the original footage to look at would be very helpful.
Judging from the scene though it looks like your shot has no parallax which can cause a solve to go awry.
you need to track more of your footage than that little cluster in the bottom of your clip. your low solve is a false positive, there is no depth in the track what so ever
Oh you can’t track 3d objects in blender with 2D tracking yet? I’d love to suggest that feature as other trackers like the one in Flame can. You get lovely change in perspective for simple things like this. It really works a charm!
That’s object tracking which is different from what I was talking about. I didn’t know you can object track in blender though so that’s pretty cool
In Flame you can 2D track a feature on the plate, place the geometry in your action node and pipe the tracking info from the tracker to the 3d geometry. So you get geometric distortion without having to do a full on camera solve. It works great for dolly shots on the xy axes.
No, just your standard, everyday 2d point tracker.
Planar tracking requires 4 points and as a result youre working with corner pin data which is not the case. Flame does have a nice planar tracker and im sure you could use it instead to an extent but a simple single point tracker would work great in this case.
Using the method I describe above the amount of geometric distortion depends on the camera’s fov(camera in action node), not the tracking data itself.
Yes! Didn’t even know blender had that capability I never do my tracking in blender because nobody looks for blender tracking skills on a resume around these parts which is why I am ignorant of some of the tracking features in blender. So yes that’s essentially the same concept.
