About Video Trimmer
Last updated: May 2026
OptiPix Video Trimmer 允许您直接在浏览器中剪切和修剪视频文件。上传 MP4、WebM、MOV、AVI 或 MKV 文件，设置精确的开始和结束时间，然后导出修剪后的剪辑。支持保留选区和移除选区模式。使用 FFmpeg.wasm 进行处理 - 复制模式可快速修剪而无需重新编码，或重新编码以进行帧精确剪切。您的视频永远不会离开您的设备。
How It Works
FFmpeg.wasm 使用 -ss (开始) 和 -to (结束) 标志来修剪视频。复制模式 (-c copy) 速度快，但依赖关键帧。重新编码模式可提供帧精确剪切。
Use Cases
- •为社交媒体修剪视频
- •从录制文件中剪切片头/片尾
- •从长视频中提取片段
- •修剪屏幕录制
- •剪切视频以用作电子邮件附件
