From script to finished video

  1. 1

    Make the clip

    Generate the video in the video studio with Seedance 2.0 or Seedance 2.5. Seedance 2.0 clips run from 4 to 15 seconds, so write a script that fits the length you pick.

  2. 2

    Write for the ear

    Short sentences with one idea each, the product or topic early and the call to action last. Read it aloud once against the clip to check the timing.

  3. 3

    Pick a voice and generate

    Choose a voice in Text to Speech and set the speed between 0.5x and 2x so the read fits the cut.

  4. 4

    Put picture and voice together

    Download the voiceover and lay it under the clip in any editor, or attach it in the video studio as one of up to 3 audio references and describe in the prompt how the clip should use it.

Native video audio and a scripted voiceover

Seedance 2.0 and Seedance 2.5 clips can include native audio generated with the picture, and on Seedance 2.x that native audio adds no extra credits. That sound comes from the prompt: ambience, effects and the feel of the scene.

A voiceover from Text to Speech is the part you control word for word: you write the exact script, choose the voice and set the delivery, and it costs 1 credit per 1,000 characters. Most videos use both: native sound for the scene and a voiceover for the message.

Voices made for voiceovers

Catalogue voices tagged for ads and voiceover work, under their real studio names. Every voice is one click from Text to Speech.

A voiceover for every format

Shorts, Reels and TikTok

A bright, quick voice with the speed nudged up keeps pace with fast cuts. Put the hook in the first sentence.

Ads and promos

A confident read with the product name early and the offer last. Two-speaker mode suits ads with two characters.

Explainers and demos

A steady voice at normal speed, one step per sentence, timed to what is on screen.

The same video in more languages

14 languages have preset voices, and Audio Generation speaks 24 languages from a written prompt.

Tips for a voiceover that fits the cut

  • Write numbers, prices and abbreviations the way they should be read.
  • Use punctuation for pauses: a comma for a breath, a full stop for a longer beat.
  • Generate two or three takes at different speeds and keep the one that fits the edit.
  • Set the voice volume in the studio so it sits clearly above the native sound or music.

Pricing

A voiceover costs 1 credit per 1,000 characters, with a minimum of 1 credit per clip: a full 5,000-character script costs 5 credits. The studio shows the cost before you generate, and failed clips are refunded automatically.

AI voiceover questions

Is the voiceover included in the video price?

No, it is a separate Text to Speech clip at 1 credit per 1,000 characters. The native audio a Seedance 2.x clip generates with the picture adds no extra credits.

How do I add the voiceover to my video?

Download it from Text to Speech and place it under the clip in your editor, or attach it in the video studio as an audio reference (up to 3 per generation) and describe in the prompt how to use it.

How long can a voiceover be?

Up to 5,000 characters per clip, far more than a short or an ad needs. For longer videos, split the script into parts.

Which languages can I use?

14 languages have preset voices, 45 voices in all. For other languages and accents, Audio Generation speaks 24 languages from a prompt.

Can I use my own voice?

Yes. Clone your own voice from 10 to 30 seconds of clean speech for 60 credits, with your consent recorded, and pick it under My Voices.

Which platform does the audio studio run on?

Built on BytePlus, ByteDance's official AI platform. KreatorFlow is an official BytePlus partner; the audio studio and its credit prices are KreatorFlow's own.
