中文说明
两个修复，都是用户反馈来的。
- 抽帧全黑探测：HEVC/H.265、AV1、10bit HDR 这类片源，浏览器读得到时长却解不出画面，以前会一声不吭地抽出几千张纯黑图。现在开头连续 30 帧纯黑就当场停下，提示先转成 H.264 的 MP4 再导入。黑底白字的片头 logo 不会被误判
- 字幕超长闸门：内嵌提取或手动导入的字幕明显长过影片（错版字幕常见）时弹出提示，可一键裁掉超出部分，不再把时间轴横轴撑长
English
Two fixes, both from user reports.
- Black-frame detection: for HEVC/H.265, AV1 and 10-bit HDR sources the browser can read the duration but cannot decode the picture, and the tool used to silently extract thousands of pure-black frames. It now stops as soon as the first 30 frames are all black and tells you to convert to H.264 MP4 first. Dark title cards with white text are not misdetected
- Subtitle length gate: when embedded or manually imported subtitles run noticeably longer than the film (common with mismatched subtitle versions), a prompt lets you trim the excess in one click instead of stretching the timeline
