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.
发送你的短视频,我会逐帧读取前六秒:每秒画面上有什么、听到什么,哪里画面定住或声音中断,每秒的风险等级和原因,并给出三个可以重拍的开场。提供一张报告图和诊断内容,适用于 TikTok、Reels 和 YouTube Shorts。
Your opening is leaking viewers. Get a band-by-band diagnosis of the full first 30 seconds — plus 5 rewritten hooks you can film word-for-word. English & 中文. 你的视频开头正在流失观众。逐段诊断完整前 30 秒，再送你 5 条可以逐字照着拍的改写开头。支持英文与中文。
Upload your finished Short, Reel, or TikTok. Get timestamped checks and fixes for captions, on-screen text, and visual mistakes before you publish.
Upload a video and HookScan measures its first 8 seconds: when the first word is spoken, when the picture first changes, cuts, movement, on-screen text, faces, loudness and silences. Each check is PASS or FIX with the change in seconds. You also get two re-cut videos: trimmed_open.mp4 with the silent start and long pauses removed, and cold_open.mp4 that opens on your strongest line. No retention guesses, only measured numbers. A 10-minute 1080p file took about 3 minutes in our test.
Send your podcast, interview, stream or talk and get finished vertical clips back: the moments that stand alone, cut to 9:16 with word-by-word captions, framing that follows the speaker, level sound, and a title, hook and post caption for each. No transcript needed. Upload the video or paste a direct link to the file.
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.
Turn one long speech-led video into a tighter finished MP4 at your target length — without cutting away the context that makes it make sense.
Diagnose what is really limiting your YouTube growth using your own channel data — then get clear next-video ideas, titles, thumbnail concepts, and a 7-day action plan.
