How does percentage translate to audio gain?

It is linear: 50% uses 0.5 gain, 100% uses 1.0 and 200% uses 2.0. Zero produces silence.

When does Prevent clipping affect the result?

Attenuation at or below 100% is left exact. Amplified audio is limited only when necessary to reduce peaks that would clip.

Does moving the slider repeatedly encode the video?

No. Preview gain changes immediately through the playback path; full media processing begins only after the primary action is clicked.

Can this tool adjust a video with no audio track?

No. A usable soundtrack is required because the operation changes existing audio rather than adding a new track.

Frequently asked questions

About Adjust Video Volume

Adjust Video Volume separates listening from export. Linear gain is applied instantly to the preview, making the difference between attenuation and amplification audible before the media pipeline processes the file.

Optional peak protection intervenes only when amplified samples need it; it does not cancel quieter settings. The output retains video timing, frame geometry and synchronization, with compatible video streams copied where practical.
