Video Voiceover

Record Your Voice Over a Video.

Record narration with your microphone while the video plays, then mix it with the original sound.

Your file stays on your device. Nothing is uploaded.

Explaining a screen recording, narrating a recipe, dubbing a product demo: each needs your voice laid over footage you already have. Here the video plays while you talk, so your words land on the right pictures without any syncing afterwards.

When you stop, two sliders set the balance. Keep the original sound at about a quarter under your voice, or pull it to zero and be the only thing heard. The picture is copied untouched, which makes the export fast.

How to use the Video Voiceover tool

  1. Add the video and move the preview to where you want to start talking.
  2. Press Record my voice, speak while the video plays, and press Stop.
  3. Set the two volume sliders and press Add the voiceover.
  • Narrating tutorials and screen recordings
  • Commentary over gameplay or sports clips
  • Replacing noisy on-location sound with a clean explanation

Tips for the best result

  • Wear headphones if you tick the option to hear the video while recording. From speakers, the microphone records the video sound a second time.
  • Record in a room with curtains, carpet or a full bookshelf. Bare walls add an echo that no setting removes.

Frequently asked questions

Can I record the voiceover in several takes?

One take per export. For a second section, run the finished video through the tool again and start recording at a later point.

I already have a narration file. Can I use that?

Yes. Press Choose a recording and pick an MP3, WAV or M4A. It starts at the point the preview is at.

Will the video quality drop?

No. Only the sound is re-made. The picture stream is copied bit for bit.

Does it work on a phone?

Yes, in current Chrome and Safari. The browser asks for the microphone the first time.

Why is my voice quieter than the music?

Lower the original sound slider to 20% or less. Music is mastered much louder than speech.
