AI movie recap tools look cheap until you price the GPU time

Everyone is building an AI movie recap tool right now. The demo takes 60 seconds, so the unit economics look obvious: charge $20, spend $1 on compute, keep the rest. Then you run it in production. A 2-hour film becomes 260+ scenes after shot detection. Each narration line has to be matched to the right scene, which means CLIP embeddings, a transcript anchor, and a vision re-rank when the match is uncertain. A 60-second recap takes about 7 minutes of GPU and costs around $0.2

AI 分析

痛点：AI视频摘要工具在GPU成本不可预测和失败任务上浪费钱，需要预检和动态定价方案。

目标用户：AI视频工具开发者，特别是做电影摘要/短视频生成的SaaS创业者。

证据：how do you price a product where one job can burn 7 minutes of GPU and still fail? ... the compute bill is the first thing I check every morning.

变现：提供API服务按调用次数收费，或SaaS订阅（如预检+成本估算+队列管理）。

MVP：一个视频预检API：输入视频URL，返回时长、是否有语音、预估GPU成本和是否建议处理，2周可完成。

摘要：作者分享AI电影摘要工具的GPU成本问题：60秒摘要需7分钟GPU，成本约0.20美元，失败任务（无语音、纯音乐）导致退款。他询问如何定价，并建议硬性限制视频长度、语音检查、自动退款和队列管理。
