Video Narration adds an AI voiceover to a video or audio file from a script, with no microphone or voice actor needed. Use it for explainers, product videos, training content and documentaries.
How is narration different from dubbing?
Dubbing replaces what people already say in the video with speech in another language.
Narration adds a voice (a narrator) on top of your video, reading your script.
How do I create a narration?
1. In the sidebar, under Projects, click Video Narration.
2. Upload your video or audio under File, or paste a Link (for a Google Drive link, make sure it's shared publicly). Supported formats: .mp4, .mov, .mp3, .wav, .flac and .aac, with no limit on size or length.
3. Select the Source Language (the language of your script).
4. Choose the Narrator Voice: a ready-made voice, one of your custom voices or a voice shared in your workspace. See What is the Voice Library?
5. On the right, under Settings:
Project Name: a name you'll recognise later.
Speech Model: Video Narration uses MARS8-Instruct by default, so you can direct the delivery with emotion tags. See the Emotion Tag Gradation Guide and Which speech model should I choose?
Script: upload your script as .txt or .docx. It is optional for .mp4 and .mov videos and required for audio files. There is no character limit.
Project Setup (optional): choose a folder, add a description and apply keywords so names and terms are handled correctly.
6. Click Begin Narration.
What happens next?
CAMB.AI processes your video and script and opens the project in the editor, where you can review and edit the narration line by line, change the timing and voice, add languages and export. See How do I use the editor in Video Narration?
Tips
Write the script the way you want it spoken: short sentences, numbers and abbreviations spelled out.
Pick a voice that fits the tone of the video, and preview it before you start.
Use emotion tags such as [calm] or [excited] at the start of a line to set the delivery.
Use keywords for brand and product names.
