@ultimape @KearnuLarsen IMU suits are the 8-track of motion capture. Middle child tech that's a huge pain to work with Give us a shot! We basically do what you describe (multiview mediapipe), but with a lot of extra machinery to ensure high quality kinematics. Join the discord and ask for help!

@freemocap @KearnuLarsen Would this be good for tracking gait stability changes over time with disorders like Mulitple Sclerosis? I've been looking at IMUs but the drift seems to make them non-starters. I've been thinking about multi-view reconstruction with mediapipe's pose tools.

@KearnuLarsen SCAIL looks cool, but it seems to be targetting nice-looking rendered output rather than empirically valid kinematic data. FreeMoCap is built as a scientific tool, so there a number of potential ML-assisted clean up steps that we skip bc they are not verifiably truth preserving

@freemocap But the SCAIL model for example gives you pretty good tracking, or no?

@JoanieLemercier Not yet! This was from freemocap v1.7.2 - We're working on getting FreeMoCap v2 ready for (open) alpha. It supports realtime reconstruction! V2 should be coming online some time Q1/Q2 2026. It currently lives on the `/development` branch of the freemocap github repo

@KearnuLarsen It works with two cameras, its more accurate with six. We recommend three cameras for most purposes. We support single camera tracking, but the 3d data that comes out is garbage (even with new trackers). You need multiview triangulation to produce scientifically valid 3d data

@freemocap But you should be able to do it with just 2 cameras. Heck, even one with the accuracy of today's AI depth-estimation models.

Test test - this thing on? Definitely related - Does anyone know of a viable #free-open-source "auto-post to a bunch of different social pages at once" option? Seems like that should just be a matter of a `json` full of credentials and bunch of API calls, right?
