- The timing relationship between entries is preserved
- **Preserved from target**: All subtitle text content, formatting, cue settings, and styling.
- **Modified in target**: Timestamps are updated and cue identifiers are standardized (sequential from 1).
-### Timeline Interpolation Details
-
-The sync command uses linear interpolation to handle different entry counts between source and target files:
-
-- **What is linear interpolation?** It's a mathematical technique for estimating values between two known points. For timeline synchronization, it creates a smooth transition between source timestamps when applied to a different number of target entries.
-
-- **How it works:**
- 1. The algorithm maps each target entry position to a corresponding position in the source timeline
- 2. For each target position, it calculates a timestamp by interpolating between the nearest source timestamps
- 3. The calculation ensures proportionally distributed timestamps that maintain the rhythm of the original
-
-- **Example:** If source file has entries at 1s, 5s, and 9s (3 entries), and target has 5 entries, the interpolated timestamps would be approximately 1s, 3s, 5s, 7s, and 9s, maintaining even spacing.
-
-- **Benefits of linear interpolation:**
- - More accurate timing when entry counts differ significantly
- - Preserves the pacing and rhythm of the source timeline
- - Handles both expanding (target has more entries) and contracting (target has fewer entries) scenarios
-
### Edge Cases
- If the source file has no timing information, the target remains unchanged.
-- If source duration calculations result in negative values, a default duration of zero is applied (improved from previous 3-second default).
+- If source duration calculations result in negative values, a default 3-second duration is applied.
- The command displays a warning when entry counts differ but proceeds with the scaled synchronization.
- Format-specific features from the target file (such as styling, alignment, metadata) are preserved. The sync operation only replaces timestamps, not any other formatting or content features.

-### 时间线插值详情
-
-同步命令使用线性插值来处理源文件和目标文件之间不同的条目数量：
-
-- **什么是线性插值？** 这是一种估计两个已知点之间值的数学技术。对于时间线同步，它在应用于不同数量的目标条目时，可以在源时间戳之间创建平滑过渡。
-
-- **工作原理：**
- 1. 算法将每个目标条目位置映射到源时间线中的对应位置
- 2. 对于每个目标位置，通过插值计算最近的源时间戳之间的时间戳
- 3. 计算确保按比例分布的时间戳，保持原始节奏
-
-- **示例：** 如果源文件在1秒、5秒和9秒有条目（共3个条目），而目标有5个条目，插值后的时间戳将大约为1秒、3秒、5秒、7秒和9秒，保持均匀间隔。
-
-- **线性插值的好处：**
- - 当条目数相差很大时，提供更准确的时间
- - 保持源时间线的节奏和韵律
- - 既能处理扩展（目标条目更多）也能处理收缩（目标条目更少）的情况
-
### 边缘情况
- 如果源文件没有时间信息，目标保持不变。
-- 如果源时长计算导致负值，会应用默认的零秒时长（改进自之前的3秒默认值）。
+- 如果源时长计算导致负值，会应用默认的3秒时长。
- 当条目数不同时，命令会显示警告但会继续进行缩放同步。
- 目标文件中的特定格式功能（如样式、对齐方式、元数据）会被保留。同步操作只替换时间戳，不会更改任何其他格式或内容功能。
