检测引擎全面升级：整段视频拆解从数分钟缩短到几十秒内完成。 回合切分更完整，时间覆盖更全。 稳定性与体验细节修复。 Detection engine upgrade: a full video now analyzes in seconds instead of minutes. Rally segmentation covers more of the match. Stability and experience fixes.

精调滑轨重做：指针可直接点、可拖动，相邻段自动吸附，拖动时画面跟着走，剪辑手感更准。 检测中途退出也能接着跑——重新打开会提示续跑进度，不用从头再来。 剪过的原片不再消失，随时可以回去再剪一版；选片按系统相册分组，更好找。 作品和项目支持自定义命名，成片文件名与分享卡跟着改。 相册权限未开启时，会直接说明原因并给出去设置的入口。 Rebuilt the fine-tune track: tap or drag the pointer directly, with snapping to neighbouring clips and the preview following your drag. Detection now resumes where it left off if you leave the app mid-run. Previously edited clips stay on the wall so you can cut another version any time; the picker is grouped by your system albums. Rename projects and works freely — the exported filename and share card follow the name. If photo access is denied, the app now explains why and offers a shortcut to Settings.

合成画质升级：成片默认按原片画质导出，并自动归入相册「羽球快剪」；选段更精准，作品卡直接显示源片名。 Synthesis now exports at the original video quality by default and saves to the dedicated “羽球快剪” album, with more accurate segment selection.
