summary

An automated pipeline called HowToCut converts Markdown tutorials into narrated, step-timed videos by extracting text and media, adding connective phrasing, synthesizing Text‑to‑Speech, and using Computer Vision to crop and loop visuals; it derives editing rules from an analysis of 125 web tutorials, produces 40 generated videos, and aligns voiceover, overlays, and camera motion; evaluated with N=20 user study and N=93 online survey showing effective pacing and usefulness for reviewing and following procedural tasks.
