- 优先选 MP4 保证兼容;想要网页更轻可以选 WEBM。
- 底层使用 ffmpeg.wasm,本地处理,不会把文件发出去。
视频格式转换:什么时候才需要
视频转换是浏览器本地能做的最重的一件事,正因如此,除非去向确实要求,否则不值得做。平台拒绝某个文件时才转,不要为了整齐而转。
只在需要时转换
- 1
先确认平台真的拒收
H.264 的 MP4 几乎处处能播。还没确认就转,既浪费时间又白丢一代画质。
- 2
只从母版转一次
每转一次都要重编码、都会掉一点。串起来转,损失会悄悄累积。
- 3
检查首尾两帧
转坏了容器常常会丢掉或重复边界帧,两头都要看。
视频转换常见问题
- 该转成什么格式?
- 为兼容性就转 H.264 的 MP4;除非对方明确点名别的编码。
- 转换会降低画质吗?
- 只要重编码就会,而通常不得不重编码。保留源文件,只往最终目标转一次。
- 视频会上传吗?
- 不会。转换在你的浏览器本地完成,这对私密素材很重要。
