People Segmentation Model not working

I’m currently trying to process a video by removing the background.
The outcome(even hitting the success), is the same initial video. No error, no complain but the background is still there.

I’m using FritzVisionVideo with the filter Cut Out People that uses the model People Segmentation Accurate

My setup: iOS 14.3, Xcode 12.2 and Fritz 6.1.1
