How to adjust one clip's volume without muting others
Raise or lower one clip's audio without changing the rest of your timeline. Learn when to use clip gain, track volume, or keyframes, then check the mix.
You want one video clip quieter or louder, but changing the volume seems to affect everything on the timeline. The key is to adjust the selected clip's audio level, not the volume of its entire track.
These steps work in most video editors. The control names vary, but the difference between clip-level volume, track volume, and keyframes is much the same.
Adjust the volume of one clip
- Find the clip in the timeline and identify where its sound comes from. The audio may be part of the video clip, or it may be a separate audio clip on another track.
- Select the clip whose sound you want to change. If the picture and audio are linked, check whether your editor lets you adjust the audio level while keeping them linked.
- Look for a clip-level control such as Volume, Gain, or Audio level in the selected clip's properties. Change that value, not the track's volume control. If it uses decibels, make a small adjustment of 2 to 3 dB first.
- If only part of the clip needs a change, add volume keyframes. Keyframes are points that tell the editor how the level should change over time. Add one before and after the section, then adjust the level between them.
- Play the edited section from a little before the clip through a little after it. Listen for a sudden jump in loudness, clipped or harsh sound, or a change to another clip. Adjust again, then play the full sequence before exporting.
What the result means
Only the selected clip changes
That is the expected result of a clip-level adjustment. The other clips on the track should keep their previous levels. Listen to the transition into and out of the clip, because a large difference can sound abrupt even when the edit is correct.
Several clips change together
You probably adjusted the track's volume rather than the selected clip. A track fader controls every sound routed through that track. Undo the change, select the individual clip, and look for its own level control.
The clip gets quieter, but the rest of its sound does too
A clip-level adjustment changes the whole clip. To change only a portion, use keyframes. To separate music, dialogue, or background sound that is mixed into one recording, you need separate audio sources or an editor that can separate them.
The sound becomes harsh or distorted when raised
The audio may be clipping, which means the signal is pushed beyond the level the export can represent cleanly. Lower the clip's level and check whether another effect or track is also adding volume.
How to fix common volume problems
- Undo a change that affected every clip. If the whole track changed, undo once and check which control you used. Adjust the selected clip instead of the track fader.
- Confirm you selected the audio you meant to change. Some videos have linked picture and sound, while other projects place audio on a separate track. Select the right clip and check the timeline before editing.
- Use keyframes for a short section. If the sound is too loud only in the middle, changing the full clip will also change its beginning and end. Add keyframes around the problem section and lower only that part.
- Check for overlapping audio. Another clip, music track, or voice-over may be playing at the same time. Temporarily mute one track at a time to find the extra sound, then restore tracks you still need.
- Reduce effects that add level. Compression, normalization, or other audio effects can raise the output after you lower the clip. Bypass effects one at a time and listen again, then adjust the clip and effects together.
- Preview the exported file. If the timeline sounds right but the export does not, check the export settings and listen to the saved file in a media player. This helps distinguish a timeline adjustment from a playback or export issue.
Clip volume and track volume are different
Clip volume changes one item in the timeline. Track volume changes the combined sound of every item on that track. Use clip volume when one recording is too loud or quiet, and use a track fader when all the clips on that track need the same change.
Keyframes are useful when the level should change during a clip, such as lowering background music under speech and bringing it back up afterward. Add gradual changes where possible, since an instant level jump can be distracting.
After adjusting a clip, listen to the entire mix at a comfortable playback level, not only to the clip by itself.
