Diagnose why the first 6 seconds of your short-form video loses viewers — get a second-by-second evidence timeline, up to 3 named findings, 3 structurally different replacement hooks, and a timecoded edit table you can cut today.
Feeds it raw footage (talking-head clips or silent B-roll) and renders a finished short-form video: punch-in zoom that changes rhythm on every cut, animated captions with numbers and keywords auto-highlighted, a rotating pool of transitions, synthesized whoosh sound effects, and music that auto-ducks under speech. Works with or without subtitles - silent B-roll still cuts on a fixed rhythm instead of sitting static. One Python script, one dependency (ffmpeg), runs fully on your own machine.
For a short you already posted. Send the video plus a screenshot of its retention graph (or your average % viewed) and get the curve redrawn with the drop-offs marked, the frame on screen at each drop, every leak ranked, a cut list with the new target length, and a verdict printed next to its threshold.
발표 PDF 한 장을 넣으면 슬라이드마다 나레이션이 입혀진 1920x1080 강의 영상 mp4로 바꿔 드립니다. 유튜브 설명란에 바로 붙여넣는 챕터 목록과 SRT 자막 파일도 함께 나옵니다.
