Features
视频脚本文案时长分割器(Video Script Duration Splitter)是一款免费浏览器端工具,面向短视频博主、口播主播、编导、后期剪辑:输入一整段口播脚本(中文、英文、数字都可),设置目标总时长(秒)或语速(每分钟字数 WPM),工具会按标点 + 语义停顿自动切成几十条小分句,给每句估算时长、累积时间戳,直接导出可以送进剪映 / CapCut / Premiere 做字幕对齐或录屏口播时的『提词器分镜稿』。
Script Splitter estimates narration, dialogue and pause timing from a pasted script, groups lines into 15-second, 30-second, 60-second or 3-minute segments, and exports SRT or cue-sheet TXT files locally in the browser.
When You Need This
Common pain points this tool solves
- 抖音博主写好一条 2 分钟带货短视频口播文案,总长 420 字,输入总时长目标 120 秒,分割器自动切成 36 条小句并给每句标 1.5–4 秒的预估时长,直接导入剪映时每条字幕刚好卡在画面切换点,不用一条一条手拖时间轴
- 公开课 / 教程讲师写了 8 分钟口播稿,想录屏时每 20 秒左右停一下,用分割器按每段 18–22 秒的目标切块,每段结尾自动标『累积第 X 秒』,录屏时按时间戳切分,剪辑时再拼成一整段不会出现整段 8 分钟全录坏了要重录的问题
- 企业品牌片编导拿到客户 3 分钟品牌旁白稿,要配合画面分镜(每个镜头 2–4 秒),用分割器按标点切成短句,给每句一个精确时间预算,方便和画面分镜表一一对齐,避免旁白念到一半画面早就切走了
How to Use
Step-by-step instructions
- 把整段口播 / 旁白文案粘贴到主输入框,支持中英文、数字、常见标点,换行、空段会被自动识别成段落分隔
- 选分割策略:按目标总时长(秒)自动分配,或按每分钟字数 WPM 手动设语速(中文口播 180–240 字/分钟常见,英文 130–160 WPM 常见),也可以在每句上加额外停顿毫秒
- 查看结果表格:每句显示原文、字数、预估秒数、累积起止时间戳、段落归属。不满意任何一句的单句时长可以直接拖拽调值或手动覆盖。
- 选择导出格式:剪映字幕 srt / vtt(一条字幕一个时间片)、提词器分镜表(纯文本时间戳清单)、或 Premiere 兼容的 XML,然后直接丢进剪辑软件的字幕轨道。
How it works
Step-by-step instructions
- Format the script. Put narration on plain lines and dialogue after a speaker name and colon. Keep pause markers on their own lines so they are not counted as spoken characters.
- Set the speaking rate. Choose 180, 220 or 260 or type a custom rate. Test the estimate against a short recording of your own voice if precise timing matters.
- Choose the target duration. Pick 15 seconds, 30 seconds, 60 seconds or 3 minutes. The target controls how the tokens are grouped, not the length of the original script.
- Check the segment table. Review start and end times, characters, duration and pauses. Look for an oversized segment and decide whether the line should be rewritten, split or moved.
- Export the production files. Copy all segments, copy one segment, download SRT or download the cue sheet. The files are created in the browser and nothing is uploaded to a caption service.
By the numbers
- Token types
- 3 types: narration, dialogue and pause
- Speaking-rate presets
- 180, 220 or 260 units per minute, with a custom rate input
- Target durations
- 15, 30, 60 or 180 seconds
- Exports
- SRT subtitles and cue-sheet TXT, plus full or per-segment clipboard copy
- Data handling
- Parsing, duration estimation and file generation run locally in the browser
How we compare
| Korelyy | Other tools | Use case |
|---|
| Estimates every line, gives cumulative timestamps and exports a caption skeleton in seconds | Reflects the actual delivery of one reader but cannot be applied to a large script without repeated manual timing | Use the estimate for planning, then replace it with real audio timings when the recording exists |
| Quickly separates narration, dialogue and pauses before any audio is recorded | Is the right place for frame-accurate timing, waveform synchronisation and final cue cleanup | The exported SRT is a draft; a subtitle editor remains the final timing authority |
| Recognises speaker lines, pause markers and target-duration segments in one pass | Is flexible for writing and comments, but requires manual calculations for duration and cues | The splitter is useful when the script needs a production timeline rather than only a readable document |
| Keeps the timing model transparent and works entirely in the browser | Can generate audio or video and measure its own output, but adds dependency, cost and account requirements | Use this tool to prepare the script before choosing a voice, editor or generation workflow |
Why Choose Korelyy
What makes us better
- 同时支持目标总时长均分 + WPM 语速两种真实工作流模式:短视频创作者常用『就 60 秒卡死』,讲师 / 播客常用『我正常语速 210 字/分钟你按这个切』,一个工具覆盖两者,不用分别算 Excel 公式
- 中文分句用标点 + 语气停顿规则(逗号、句号、顿号、逻辑连接词于是 / 所以 / 但是),不是机械按字数切块,所以每条分句在口播时换气自然,不会出现『第 17 个字硬拆成半句』的尴尬
- 导出格式覆盖剪辑工作流:SRT、VTT、剪映 / CapCut 可直接导入的纯文本字幕列表,以及 Premiere XML、DaVinci Resolve 也能识别的 EDL 兼容格式,和主流剪辑 / 字幕软件完全对得上,不用每次手调字幕时间轴。
