About Video Merger
Last updated: May 2026
OptiPix Video Merger 可以在您的浏览器中直接将 2-10 个视频文件合并为一个视频。上传视频，重新排序，然后合并，支持自动格式处理。使用 FFmpeg.wasm concat demuxer 在格式匹配时快速合并，或在格式不匹配时重新编码。所有处理均在本地进行。
How It Works
FFmpeg.wasm concat demuxer 连接视频。相同格式的文件使用 -c copy 进行无损合并；混合格式则重新编码为 H.264+AAC。
Use Cases
- •将视频片段合并为一个
- •合并 GoPro 分段
- •连接采访片段
- •合并社交媒体片段
- •合并演示录制
