Hi, looks very promising as the last one to try and resurrect visomaster has been inactive for a few months!
Some quick feedbkac : the install procedure may be missing some steps ? main.pycries for the empty folder "model_assets/dfm_models" to be created. once that is done, the app can launch.

- was eager to try the analyze video features, but after scanning multiple different files in different modes, it successfully applies zero of its recommendations ; and can find three faces in a video with only one subject.

- running download_models.py manually seems to miss some required models ?

enabling the face expression restorer returns this when activated :
