I have an XT-4 (firmware v 2.11) that I’m trying to use as a webcam on macOS. As others have experienced, it works great at 1080p / 30fps for 4-5 minutes and then the frame rate significantly drops, leading to jerky video. Curiously, touching any button or knob on the camera brings the frame rate back up to normal for another 4 minutes or so. I’ve also monitored the back screen and turned on all diagnostic info on the screen and watched it while it transitioned to a low frame rate, nothing changes visibly to indicate why.
None of the other posts I’ve read have contained working solutions so far. Below is everything I’ve tried, would really appreciate any ideas for fixing this.
Tried the FujiFilm X Webcam app (didn’t work at all for me)
Multiple USB ports and HDMI cables
Multiple Macs (an M2 MBA and a Mac Studio)
Multiple versions of macOS (Sonoma 14.5 and Sequoia 15 Public Beta)
Connecting via a cheap HDMI capture dongle
Connecting via Elgato CamLink 4K
Using the Elgato Camera Hub software
Following all the directions on the FujiFilm website for using the XT-4 as a webcam
Turning power management off
Turning face detection and auto focus off
Using boost mode (frame rate priority)
Flipping the LCD to be facing out (suggested in a number of posts)
Resetting the camera to defaults and doing all of the above again
Thanks for any tips!
