Posenet workarounds / improve performance

Sorry I post mainly about the Posenet extension but I'm using it for a school project and I'm having trouble with the performace on my android tablet. I'm using the AI companion, but Is there any blocks I could implement to improve the posenet speed it processes at natively? Also I'm still looking into using pre-recorded videos which I addressed in another topic is closed, But is there any workarounds using webviewer or the camera to use pre-recorded videos for posenet?
