## Audio

* Volume: Adjust the audio volume. The adjustment range is -∞ ～ 20db, and the default is 0db. The maximum volume can be enlarged by 20db, and the minimum can be reduced to 0.
* Fade-in duration: You can set fade-in effect, and the volume will gradually increase from 0 at the beginning to normal volume. The duration is determined by the set fade-in duration.
* Fade-out duration: You can set fade-out effect, and the volume will gradually decrease from normal volume to 0 at the end. The duration is determined by the set fade-out duration.

## Speed

* Speed: You can adjust the video speed. The minimum is 0.5x, and the maximum is 16x. The larger the speed value, the shorter the video duration.
* Duration: You can adjust the speed by modifying the duration. The minimum duration is 0.1s.
* Pitch: Since changing the speed will change the audio pitch, we have adopted an intelligent algorithm by default to keep the audio pitch unchanged after the speed change. If you want the pitch to change after the speed is changed, please check the sound change.
