make-widescreen-highlight
by JieJessica
Convert vertical or non-16:9 videos into 16:9 widescreen highlight clips with a blurred full-frame background and the original video centered on top. Use when the user asks to make a video widescreen, add a blurred background, keep the original clip centered, preserve audio, extract a 10-second highlight, create social-media landscape output, or process MP4/MOV video files from Downloads or another local folder.
