mesoloplswin — Demo video

Small sellers live on video, but one product ad costs hundreds of dollars and weeks of waiting — or a generic AI slideshow that looks like everyone else's. SignalCut is a one-click video ad engine. Upload up to 8 photos, write one prompt, and a 5-stage pipeline (brief → voice → music → render → publish) produces a 720×1280 portrait MP4: a script written from your actual photos, AI voiceover, directed music bed, VO-timed scenes with depth parallax and broadcast captions, ready to post. Progress is refresh-safe and every ad lands in your reel. An adaptive direction engine (10 moods × 10 voices × 3 paces, per-mood layouts/hooks/pacing) means the same photos render visibly different bold vs elegant cuts. Everything runs local-first and free; 270 automated tests guard the release.
