Waiting for someone to create a mac compatible version!

Waiting for someone to create a mac compatible version!

Hi! I actually created a macOS-compatible fork of this AutoTracker v1.4 Batch Script, tested on my MacBook Air M4. You can check it out in the Forks tab of this gist (Click here to redirect). By the way, the README is pretty much self-explanatory but I’ll also be uploading a tutorial soon showing how to use it on macOS.

Hey the "animated camera" in the blender imported project doesn't actually have any keyframe to animate it and when i select it as camera there is also no background image showing my footage anywhere, could be that my video isn't that much good, but it still has hundreds of cameras placed with a lot of tracking points so i don't understand

I have lightly adapted @celestial-33 's wonderful Mac version to work in Linux. I haven't provided advice for installing the requirements, however (not convinced I'd do a good, broadly applicable job).

I forked and updated the script a bit: https://gist.github.com/aidv/05779c76401ae55ee6b227ee0c1e47f9

Apparently AMD GPU's are very wonky with COLMAP/GLOMAP, so forcing CPU usage is better.
