How to Add Narration and Music to AI Videos in NadouPro

NadouPro can help creators combine Voice Dubbing, Text to Music, Song Generation / Cover, Voice convert、Text to speech, Lip Sync, and Clip editing nodes in one creative workflow to build the audio portion of an AI video. For sound effects, you can use existing audio and editing workflows to plan, place, and balance audio layers, but unless it appears in your current NadouPro workspace, do not assume there is a dedicated sound-effect generator.

What NadouPro supports for AI video audio

NadouPro is an AI Professional Filmmaking & Video Creation Platform designed for work “from script and storyboard to final cut.” Its node-based workflow includes Audio nodes, Video nodes, Text nodes, and Clip nodes, so creators can move from script text to generated voice, music, video, and edited output within the same production structure.

Narration or dialogue	Voice Dubbing	Create spoken lines from a script
Controllable vocal performance	Performance Tags	Add cues for emotion, speed, pauses, whispering, shouting, laughter, or other expressions
Character mouth movement	Lip Sync	Upload video and dubbed audio so the character’s mouth movements match the voice
Background music	Text to Music	Describe the mood, genre, scene, or tempo goal for BGM
Songs or covers	Song Generation / Cover	Create music-led content where the song is part of the creative concept
Consistent voice identity	Voice convert、Text to speech	When appropriate, make the voice style more consistent across related clips
Final assembly	Clip	Edit video, images, and audio together into a finished output

A practical narration workflow

1. Write the script first.Use a Text node to write narration, dialogue, subtitles, or scene descriptions. Keep each line short enough for clear review.
2. Generate the voice track.Use Voice convert、Text to speech to generate spoken delivery.
3. Check intelligibility before adjusting style.Make sure the words are clear, the speaking speed fits the edit, and the emotional tone serves the scene.
4. Use Lip Sync when a character speaks on camera.NadouPro’s Lip Sync workflow uses uploaded video plus dubbed audio to align the character’s mouth movements with the voice.

How to add music without overpowering the voice

For background music, use Text to Music to describe the mood, scene type, speed, and emotional direction you want. For music-led concepts, when the song itself is part of the content, use Song Generation / Cover. Then bring the generated audio into the edit so it supports the voice instead of competing with it.

• Start with the scene function:tension, discovery, romance, product reveal, action, tutorial, or closing beat.
• Describe energy and rhythm:quiet, restrained, building, rhythmic, playful, urgent, or atmospheric.
• Leave room for speech:if narration is important, choose a less crowded arrangement and keep the vocal range clear.
• Match musical changes to visual changes:use edit points, reveals, or title cards as natural points for musical transitions.

What about sound effects?

Approved NadouPro product information confirms audio generation, dubbing, Lip Sync, and editing nodes, but it does not confirm a standalone sound-effect generation feature. The safe workflow is to treat sound effects as a sound-design layer: identify moments that need impact, footsteps, room tone, action, or environmental texture, then place and balance available audio assets during editing. If your NadouPro workspace shows additional sound-effect tools, verify their current behavior in the product before using them for production-level claims.

Recommended end-to-end workflow

1. Plan sound during the storyboard stage.Mark which shots need narration, dialogue, music, silence, or impact sounds.
2. Create or import visual clips.Use NadouPro’s video workflows, such as Text to Video, Image to Video, First/Last Frame, Multi-reference, or other available video nodes.
3. Create voice tracks.Use Voice convert、Text to speech to generate narration or dialogue.
4. Sync speaking characters.When a visible speaker needs mouth movements aligned with the voice track, use Lip Sync.
5. Generate music.Use Text to Music or Song Generation / Cover depending on whether you need background scoring or song-led content.
6. Assemble in Clip.Combine video, images, and audio, then review timing, clarity, and transitions.
7. Do a final listening review.Check whether dialogue is understandable, whether the music supports the mood, and whether the sound layers do not distract from the story.

Prompt structure for better audio planning

When describing video or audio ideas in NadouPro, break the sound brief into clear layers. A useful structure is: scene mood, spoken lines, performance tone, music style, and any sound-design notes that should be handled in editing.

Example structure:A quiet nighttime street scene. The narration is calm and reflective. Dialogue line: “We arrived too late.” Use a restrained, slow musical mood. Leave room in the edit for footsteps and distant city ambience.

This kind of prompt does not guarantee a specific output, but it gives the project a clearer audio plan and makes review easier.

When NadouPro is suitable for video audio work

NadouPro is especially useful when you want audio to stay connected to the broader filmmaking workflow instead of being treated as an afterthought. Its strength lies in combining script text, voice generation, music generation, Lip Sync, node-based media connections, and Clip-based assembly within a platform built for AI filmmaking.

To try this workflow, open NadouPro, prepare a short script, generate a voice track, add music, and review the result in an edited sequence before extending the process to longer videos.
