说明Good to know

  • 格式允许时，视频画面不重新编码，速度很快；否则会重新编码，会慢一些。The video picture is copied without re-encoding when its format allows it, which is fast; otherwise it is re-encoded, which is slower.
  • 音频会转成 AAC。视频原来的声音会被替换，而不是混合。The audio is converted to AAC. The video's original sound is replaced, not mixed.
  • 视频上限 200 MB，音频上限 100 MB。第一次使用要下载约 10 MB 的处理组件（之后会缓存）。Limit 200 MB for the video and 100 MB for the audio. The first use downloads a 10 MB processing engine (cached afterwards).
