Face Tracker

Face Tracker 0.7.1


Using this plugin makes the output image very dark. What am I doing wrong?
Probably I made something with wrong for a specific source type. Could you provide a little more detailed information including your device, color format, color space? If you don't mind, log file of obs-studio would be helpful.

This isn't my setup and I only use it once in a while.

Camera is Blackmagic Cinema Camera 6K going through a Blackmagic Design ATEM Television Studio Pro HD Live Production Switcher.
Color Format: NV12 (8-bit, 4:2:0, 2 planes)
Color Space: Rec. 709

Log file and source info attached.

Thank you for this plugin!

I'd like to know if it's possible to modify the Kp, Ki, Td (or other) values to obtain "instantaneous" tracking of the face. Can we eliminate smoothing, or easing, while keeping error (noise) deletion?

I've recently upgraded my ubuntu to 23.10. Now OBS won't start with obs-face-tracker installed. My output is the following:

Hey there! Wondering if there's a way to reset the tracker to default (before it zooms in) when turning off the source in OBS). So basically it can zoom in any time I press it instead of staying zoomed in. Thanks!

Using multiple cameras (2 or 3) it would be nice if when I turn to look to the right that it switch scene to the camera on my right and when I turn left switch scene to the camera in the center or to my left. Basically, Turn Left scene 1 (camera 1), turn center scene 2 (camera 2) turn right scene 3 (camera 3). Is this doabe?

Hello @norihiro i have a question. norihiro is it possible, that the smooth zoom starts everytime when i switch to the Szene where my Facetracker is. So that it doesnt remember where the last zoom was and it has to zoom again every time when i switch on the Szene.

Sorry for my bad englisch. I hope you understood
