Can I add a voiceover to a video I already finished editing?

Yes—that's the core workflow. Upload the finished video, mute or keep the original audio, and generate the narration on a parallel track aligned to your existing cut.

How do I keep the narration in sync with my scenes?

The voiceover is generated on the timeline against your visuals, so you see the alignment as you go. Insert pauses or split the script per scene, and the read snaps to where each section starts.

Is the audio actually delivery-ready, or do I need to master it?

It comes out mastered: normalized loudness, EQ for vocal clarity, and compression for consistent volume. For client work you can export and deliver without an audio pass.

What happens to my background music when the narration plays?

Auto-ducking lowers the music while the voice speaks and brings it back in the gaps—the standard broadcast mix, applied automatically.

A client wants one line changed. Do I regenerate everything?

No. Edit that sentence in the script and regenerate just that line in the same voice. The rest of the track, and its sync, stays untouched.

Can I do a two-narrator or dialogue-style voiceover?

Yes. Assign different voices to different script blocks on the timeline—useful for conversational ads, Q&A explainers, and character reads.

Can I export just the audio for use in another editor?

Yes. Export the full video as MP4, or download the isolated narration as MP3 or WAV and drop it into Premiere, Resolve, or wherever the project lives.

Am I allowed to use this on client and ad work?

Yes. Paid plans include a full commercial license covering client deliverables, paid ads, and monetized platforms.

How much voiceover can I generate per month?

It depends on your plan tier, but paid tiers are sized for production use—daily content schedules and multi-project client loads included.

AI Voiceover Generator

The video is edited. The explainer, the product demo, the ad—done, except it's silent. Booking a voice actor means quotes, revisions at an hourly rate, and a week of back-and-forth for a 90-second read. Eliro generates the narration directly on your video's timeline: write the script, watch the read align to your visuals, and export a mastered mix the same afternoon the client asked for it.

From Silent Cut to Mastered Mix

The narration workflow, compressed from a week to an afternoon

Narration on the Timeline Itself

The voiceover generates against your actual edit, scene by scene. No exporting audio from one app and nudging clips around it in another—the read lands where the visuals need it.

Pre-Mastered, Broadcast-Ready Audio

Every read comes out normalized, EQ'd for vocal presence, and compressed to consistent volume. No room echo to treat, no levels to ride before delivery.

Auto-Ducking Under the Narration

Your background music drops automatically whenever the voice speaks and recovers when it stops—the mixing move that separates client-ready audio from amateur mixes.

Revisions Without Re-Booking

Client changed one sentence? Retype it and regenerate that line in the same voice. The eleventh revision costs the same as the first: nothing.

Narrate a Finished Video Without Re-Editing It

Step 1

Bring In the Edit and the Script

Upload your finished video and paste the narration script. If the copy isn't written yet, the AI writer can draft it from your video's content.

Step 2

Cast the Read

Pick a narrator from the premium library—or your own cloned voice—and set the delivery: measured for an explainer, punchy for an ad.

Step 3

Align, Mix, Deliver

Preview the narration against the picture, add pauses where scenes need to breathe, and export the final video with a mastered voice track.

What a Narration Session Looks Like in Eliro

Your Voice on Every Video, Recorded Once

Agencies and channel owners clone their narrator's voice from a one-minute sample, then ship every future explainer and ad in that voice without booking studio time. The narration stays on-brand even when the person behind it is unavailable.

Cast the Right Narrator for Each Project

A pension explainer needs gravitas; a sneaker ad needs energy. Audition hundreds of premium voices across 30+ languages on your actual script, and deliver localized versions of the same video without re-hiring talent per market.

The Read Follows Your Cut, Not the Other Way Around

Because narration is generated on the timeline, pacing adapts to your scenes—pauses land on visual transitions and emphasis falls where the picture is pointing. You stop re-cutting video to fit an audio file someone sent you.

Finish the Audio Post, Then the Video

Narration is the lead vocal—these tools complete the mix and the delivery.

Background Music

A music bed that auto-ducks under your narration, mixed without touching a fader.

Sound Effects

Accents and transitions timed around the narration so the mix supports the read.

AI B-Roll Generation

Cover sections where the narration outruns your footage with AI-generated B-roll.

Auto Zoom & Pan

Visual emphasis on the lines your narrator stresses, without keyframing.

Publish & Schedule

Deliver the narrated video straight to YouTube and social platforms, or hand off a clean export.
