Background

A student downloaded a recorded lecture video, but the professor's voice is extremely quiet and hard to hear even at maximum device volume.

Problem

The audio needs to be amplified significantly without degrading the video quality or taking too long to process.

How to use

Upload the lecture MP4, set the volume slider to 250%, keep 'Copy Video' checked to avoid re-encoding, and select MP4 as the output format.

Volume: 250%, Output Format: MP4, Copy Video: Enabled

Outcome

The student receives a new MP4 video where the professor's voice is loud and clear, processed instantly without any loss in video resolution.

2. Mute Background Noise for Social Media

Background

A creator captured a great B-roll video outdoors, but the background wind noise is distracting and needs to be removed before adding a voiceover later.

Problem

The original audio track must be completely silenced while keeping the video stream untouched.

How to use

Upload the raw MOV video file, set the volume level to 0%, select WebM as the output format, and run the tool.
