QastX for YouTubers: turn long uploads into a week of Shorts
AI scans your hour-long video, finds first-second hooks and exports them as ready-to-post Shorts with subtitles. No manual editing.
The YouTube algorithm rewards channels that post Shorts consistently — 1–2 a day measurably lifts long-form recommendations. But hand-cutting Shorts from your own videos costs 2–3 hours per clip. QastX does it automatically: upload your source (file or link), the AI pulls 5–15 hook-driven moments, reframes them to 9:16 with face-tracking, burns in subtitles and ships the files. One uploaded one-hour video = a full week of Shorts.
How QastX helps
You run a long-form channel and don't post Shorts because editing takes forever.
Drop your last 40-minute video into QastX → get 8–12 finished Shorts.
Result: One upload → a week of daily Shorts. The channel grows faster, long videos get more impressions.
You record interviews and the show has bomb moments — but timestamping them by hand is brutal.
AI walks through the speech and flags emotional peaks, surprising answers, complete thoughts.
Result: 10–15 Shorts with the strongest quotes, no re-watching the episode.
You need to ship Shorts from a fresh long video right now to hit your posting schedule.
Upload the source → AI cuts a full pack of clips for the week.
Result: 10 minutes from upload to a ready Shorts pack.
