你好，以下是我用 AI 生成的 issue 报告，谢谢开发者。

标题

Bug: DataFrame creation fails due to mismatched array lengths in step5_splitforsub.py

问题描述

在处理字幕分割时，程序在 step5_splitforsub.py 中创建 DataFrame 时报错，显示源文本和翻译文本的数组长度不匹配。

复现步骤

1. 启动 VideoLingo
2. 上传视频并完成翻译
3. 在字幕处理阶段出现错误

环境信息

• Python 版本：3.10
• 操作系统：macOS
• VideoLingo 版本：[您的版本号]

建议修复

建议在创建 DataFrame 之前添加数组长度检查，确保 src 和 remerged 数组长度一致。可以考虑在 split_align_subs 函数中添加数据一致性验证。

• core/step5_splitforsub.py

Start in core/step5_splitforsub.py at line 131, where split_for_sub_main creates the DataFrame, then inspect the split_align_subs path that produces src and remerged. Reproduce the subtitle-processing workflow from the issue and compare the two array lengths before DataFrame creation. Done means the reported workflow no longer raises the mismatched-length error and the resulting output remains aligned.
