How it works
- Upload a video
Tap Upload video and pick an MP4, MOV, WebM or another video, up to 2 GB.
- Record your voice
The editor opens on Sound. Drag the timeline to where you want to start and tap Record voice. Your browser asks for the microphone; after 3-2-1 the video plays and you speak. Tap Stop when you are done.
- Listen and save
Play it back with the video. Keep Mix and Lower the original while I speak, or choose Replace to keep only your voice. Then tap Add voice now.
Your voice starts where you do
The recording starts at the moment of the video where you tapped Record voice, so it stays in step with the picture. Not happy with it? Tap Record again, or Delete.
The video steps back while you talk
With Lower the original while I speak, the video’s own sound gets about 10 dB quieter while your voice is heard, and comes back after. Turn it off to keep one level, or choose Replace for your voice alone.
Headphones to hear the video
While you record, the video plays muted, so its sound does not get into the microphone. To hear it, turn on Hear the video while I record — and use headphones.
The microphone only when you ask
BasePic turns the microphone on only when you tap Record voice, and off when you stop. The new video with your voice is an MP4 with its own link; the original does not change.
Add voiceover to video: questions
How do I add a voice-over to a video?
Upload the video, tap Record voice under Sound and speak while the video plays. Tap Stop, then Add voice now.
Can I record over only part of the video?
Yes. Drag the timeline to the moment you want and tap Record voice there; your voice starts at that moment. Trim the video if you want only that part.
Can I keep only my voice?
Yes. After recording, choose Replace, and the video’s own sound is removed.
How loud is my voice?
Set Voice from 0 to 200 %. In Mix, the video’s own sound plays under it.
Is it free?
Yes. No sign-up and no watermark.
