A clearer handoff. / 使用指南
Open once. Work carefully. Export with context. Kitmaple Subtitles helps you prepare existing subtitles for delivery, without uploading your files.
导入一次，细致整理，再带着清楚的结果交付。Kitmaple Subtitles 用于处理已有字幕，所有字幕操作都在本地完成。
01 · Check & repair / 检查修复
Reading limits default to 20 non-whitespace characters per second and 42 characters per line. These are adjustable screening rules, not universal delivery standards. Your chosen thresholds survive edits and tool switches. The queue can show all cues or just an issue type; choose a cue to inspect and edit its time and text. “Preview fixes” shows selected cleanups before applying them. Overlaps and reading speed are never changed automatically.
默认每秒 20 个非空白字符、每行 42 字，可按语言与交付要求调整。阈值在编辑和切换工具后会保留。按问题筛选队列，选中字幕即可编辑；修复先预览后应用。重叠可能是有意的，不会自动消除。
02 · Review revisions / 改版复核
Choose an old reference and a new delivery file in the same language. Matching preserves cue order and detects text/timing changes and exact splits or merges of up to three cues. Repeated phrases are marked ambiguous; reorders or complex regrouping may appear as added/removed. Mark reviewed items individually. The primary subtitle download always exports the new version. Editing an input resets its review decisions. The CSV includes reviewed flags and old/new time boundaries.
选择同语言的旧版参考与新版交付文件。识别文字、时间、增删以及最多三条字幕间的精确拆合。重复句需确认对应关系；重排可能显示为增删。逐项标记已复核，主下载按钮始终导出新版。修改输入会使之前的复核结果失效。此工具不会翻译或自动迁移译文。
03 · Save your work / 保存工作
“Save project” downloads a local JSON file containing originals, edits, reading limits and review progress. Use “Open project” to continue later. There is no automatic persistence or cloud synchronization. A saved project contains subtitle text: share it only with intended collaborators.
保存项目会下载本地 JSON，包含原稿、修改、阈值和复核进度。重新打开项目即可继续，应用不会自动保存或云端同步。项目含字幕内容，请只分享给合适的协作者。
Quick tools / 实用工具
Convert between SRT and WebVTT or download a batch ZIP. Timing shifts accept positive (later) and negative (earlier) offsets for a whole file or range; invalid shifts are blocked. Bilingual merging pairs equal cue counts within 500 ms on both boundaries and uses the first track’s timing. Splitting uses a fixed line boundary, not language detection. Text extraction removes timecodes and formatting tags.
可转换 SRT/WebVTT、批量导出 ZIP、整体或分段调时。双语合并要求条数一致且起止时间差均不超过 500 毫秒；拆分按固定行号进行，不检测语言。提取文本会去除时间码与格式标签。
Limits & format details / 使用边界
- Up to 20 files per project, 2 MB and 10,000 cues per subtitle. Project JSON up to 12 MB.
- Revision comparison: 600 cues per version and 120,000 combined characters. For longer material, split into chapters first.
- SRT and WebVTT only. NOTE, STYLE, REGION and WebVTT header metadata are not exported. Cue positioning is retained only in WebVTT.
- Inline formatting is retained unless explicitly stripped. The editor shows literal tags; the caption layout preview shows plain text, not video playback.
- Undo retains 30 edits per open file. Project files restore the current/original state, not the undo history.

Before delivery / 交付前
Keep the original, inspect the exported file, and watch it with the actual video. Rule checks cannot establish translation accuracy, speaker identity, or audiovisual synchronization.
请保留原稿，检查导出文件，并结合真实视频复核。规则检查不能证明翻译、说话人或声画同步的准确性。
