OpenShot 4.0 put local ML subject masking inside an open-source editor.

Released August 30 after about a year, porting the UI from Qt5 to Qt6 with a redesigned native timeline and adding screen, webcam, microphone and system audio recording (OpenShot). The AI parts run locally: subject isolation via ML masking, a YOLO model picker for the object detection filter, ComfyUI templates for audio denoising, repair and voice enhancement. 570 points on Hacker News. Local inference inside a general-purpose FOSS editor rather than a cloud add-on is a choice more projects should be making.
