Original Summary

so i build retake. it records a real product demo and can rerun it after the ui changes. someone tried it a while back and told me it just wasnt good enough. no real explanation, no bug list, just that. my first instinct was to ask for specifics. instead i went and watched a couple of the videos they'd already made themselves. that was the answer. their cursor moved like an actual person was moving it. mine moved at one constant speed then just stopped dead. technically nothing was broken, page opened, click landed, file rendered, every check passed every time. none of that tells you whether a human would actually want to post the result. i redid the cursor movement so it eases into a stop instead of snapping. gave the important clicks more room to breathe. used a slow zoom here and there when it actually helped. small stuff. fixed more than a new feature would have, because it touches every single recording the tool makes. voice only got added once the movement felt right on its own. tried a few models before landing on one. microsoft's is the easiest to wire up, which is exactly the problem, your script goes through their servers. ended up preferring something that runs locally even though its heavier. timing the narration to match the screen turned into its own fight, had a version where the voice was already two steps ahead of what was on screen. onboarding got gutted too. most people show up with an ai agent already doing the setup for them, so handing them a guide to read first never made sense. it just asks what it actually needs now and passes that straight to the agent. three.js recordings still dont work reliably. tried it. some runs look fine, some dont. not going to pretend thats solved when it isnt. anyway. the boring fix mattered more than a new feature would have. still feels obvious in hindsight.   submitted by   /u/Guilty_Lingonberry [link]   [comments]

中文标题： 有人说我的演示工具不够好，看他们自己的视频才明白原因

作者开发retake，可录制真实产品演示并在UI变更后重放。曾有用户只说不够好却不给细节，作者观看对方自录视频后发现差距在光标移动：自己工具的光标匀速移动后生硬停止。于是改进光标缓停、给关键点击留节奏、适当加慢速缩放，并改用本地运行的语音模型配旁白（弃用微软需过服务器的方案），简化了新手引导。three.js录制仍不稳定，作者坦承未解决。
