Reaction video audio: balance the clip and your voice
If viewers can't hear your commentary, the reaction is dead. Here's how to duck the source under your mic and balance the mix — automatically in ClipCam, or manually anywhere.
A reaction video lives or dies on audio. If the clip you're reacting to drowns out your commentary, viewers bounce. The fix is "ducking" — automatically lowering the source whenever you speak — plus a final balance pass. ClipCam does the first for you and makes the second one tap.
Ducking, handled automatically
While you record, the source clip's audio drops the instant you start talking and rises back when you pause. Your voice stays the loudest thing in the mix without you riding a fader or setting a single keyframe.
Balance it before you export
On the preview screen, two sliders control the final mix:
- Source — how loud the clip you reacted to plays.
- Your voice — your microphone level.
Tap preview, listen, nudge, repeat. When it sounds right, export.
The headphones gotcha
If you record with headphones, your mic never picks up the source — so you keep both tracks. If you record without headphones, your mic already captured the clip's audio through the speaker. Leaving the source track up then doubles it and sounds muddy. The fix: drag Source down (or mute it) and let your single capture carry the take. ClipCam hints at this on the preview screen.
Where it lives
Audio balancing sits on the preview screen alongside Suggested clips and the resolution picker. Read the full feature at /audio-mixing, or see the whole workflow at /how-it-works.
