Kdenlive 25.04.0 已发布

2025年 4 月 28 日 星期一  |  Jean-Baptiste Mardelle

#Release  

我们荣幸地宣布 Kdenlive 25.04.0 现已发布。以下是本次大型更新的重点内容：

对象分离

基于 SAM2 模型的新插件，现在能够帮助您创建对象蒙版，您可以用它来去除视频背景，或对某个特定元素应用特效。所有的画面处理都会在本地进行。

改进的时间线音频波形

Etienne André 对时间线进行了一次精心的重构，音频缩略图的生成现在更加快速，也更准确。

OpentimelineIO 导入/导出

Darby Johnston 使用 C++ 库重写了我们的 OpentimelineIO 导入和导出功能。您现在可以与其他支持这种开源格式的视频软件交换项目。但请注意，特效、滤镜和转场将不会被导出，毕竟每个程序都使用自己的标准。

工作流改进

本次更新还包含许多小型改进，以下是一些值得注意的更改：

  • 通过一步操作即可更改多个相邻片段的持续时间
  • 允许垂直缩放音频波形
  • 修复包含 Alpha 通道视频的代理剪辑生成工作流
  • 添加了 Shift + 单击操作，以快速展开或折叠特效堆栈中的所有效果
  • 时间码小部件现在使用不同的颜色区分，因此更容易找出当前活跃的监视器
  • 在项目注释中添加了搜索功能，并且让标准的搜索快捷键在所有的部件上起效。
  • 修复了界面文本在已翻译的状况下仍然显示不正确的问题
  • Kdenlive 现在会记住最后使用的 LUT 校色文件，让您在调色过程中更容易访问
  • 修复了 Mac 上渲染部件被隐藏在主界面后方的问题

本版还包含许多其他改进，我们同时解决了 30 余个已报告的错误。请阅读下方的更新日志了解更多细节。

最后一刻修复

一些在版本发布前最后一刻的修复也包含在我们的程序中：

  • 修复了将序列片段粘贴到另一个项目中可能出现损坏的问题
  • 改进了标题编辑器的描边功能，让它更好地遵循字体曲线
  • 修复了在轨道上延展最后一个剪辑时可能引发程序无响应的问题
  • 微调了触发器和时间间隔，以降低自动保存功能的执行频率，防止一些大型项目处理时出现严重卡顿问题。

感谢所有筹款人的支持，我们的 OpentimelineIO 和音频波形改进才能顺利实施，请查看我们的最终活动报告。
