Question* PFTrack Workflow using Anamorphic footage + 360 Witness Cam
Hey all,
I’m trying to figure out how to track anamorphic footage in PFTrack using a 360 camera as a witness cam, like in this MAKE. ART. NOW. lvideo link here: (link, timestamped).
Has anyone done a workflow like this?
Any advice, tips, or examples would be hugely appreciated!

Thanks for sharing the video. This is a fairly straightforward workflow of tracking and solving the 360 camera, then applying that motion to the hero cam via a measured offset in your 3D package. That’s not quite the same as a true multi-camera track where both cameras are solved into the same scene, but you can absolutely follow this method in PFTrack using the spherical 360 tracking toolset and whatever 3D package you are exporting to.
There are a couple of important things they didn’t seem to cover:
Calibration: It doesn’t look like they calibrated the hero camera’s spherical lens. We’d recommend doing this, not necessarily for the motion transfer itself, but to get accurate distortion data if you plan to add CG later. This is especially important with anamorphic footage where distortions can complicate compositing.
Scene Scale: Make sure your scene scale and camera offsets are measured precisely. If the scale is wrong, your 360-to-hero cam offset will also be incorrect, which can throw off the whole workflow.
