Frequently Asked Questions
- How do I increase the volume of a video?
- Upload it, set the slider above 100% (200% doubles the loudness), and Process. The audio track is boosted and the video stream is copied through untouched.
- Will making a video louder reduce its quality?
- The picture: no — the video stream is stream-copied, not re-encoded. The audio is re-encoded at a high bitrate with a limiter, so the boost stays clean.
- Why is my phone video so quiet?
- Phones record with conservative levels to avoid clipping wind or shouting, so speech from a few meters away often lands very quiet. A 200-300% boost with the limiter on usually brings it to comfortable listening volume.
