promptvv - Turn any video into a structured AI video prompt

by
promptvv turns an uploaded video—or a Douyin, Xiaohongshu, or Bilibili link—into a structured prompt you can use with Jimeng, Seedance, Kling, and other AI video models. It breaks the source into events, shots, camera moves, actions, performance, and dialogue, and supports follow-up refinements. No manual downloading is needed for supported links. New accounts include 30 seconds of free analysis.

I built promptvv while working on AI video remakes with a friend. Rewriting prompts by watching a clip frame by frame was tedious, and ordinary video descriptions were not structured enough to use directly in models such as Jimeng and Seedance. The product accepts a local video or a supported Douyin, Xiaohongshu, or Bilibili link, then breaks it into events, tasks, shots, camera movement, actions, performance, and dialogue. I spent nearly a week refining the output format so the result could be copied into an AI video workflow with less cleanup. New accounts include 30 seconds of free analysis. I’d love feedback on where the reverse-engineered prompt misses the source video or which output format you find most useful.

Would love a side-by-side preview that compares the generated prompt against the original clip with timestamps, so I can quickly spot which event or camera move the parser missed before sending it to Kling.

 Great suggestion — a side-by-side timeline would make it much easier to verify each event and camera move before exporting the prompt to Kling. This is both useful and feasible, so I’ve added it to our roadmap. Thanks for the thoughtful feedback!
