How to Dub a Video with AI in Four Steps

This AI video dubbing workflow starts with a short video and a prepared target-language subtitle file. The cue timing controls when each line is spoken, so you can review the script before spending credits on the final dub.

  1. 01

    Upload a Short Video

    Choose a supported video from your device or reuse a completed MkAnime task. The workbench checks the file before generation.

  2. 02

    Add SRT or VTT Captions

    Prepare the dialogue in the language you want to hear. Each subtitle cue supplies both the spoken text and its place on the video timeline.

  3. 03

    Choose an AI Voice

    Filter the current voice catalog by language, accent, gender, or age, then select the voice that best fits the speaker and scene.

  4. 04

    Generate and Download

    Review the credit estimate, start the dubbing task, compare the original and dubbed versions, and download the finished MP4 or dialogue audio.

Where Script-Driven Video Dubbing Fits

Use this workflow when you already control the translated or rewritten dialogue and need a new timed voice track for a short video.

What This AI Dubbing Tool Does—and Does Not Do

The workbench is intentionally script-driven. These boundaries help you choose the right MkAnime voice or video workflow before generating.

You Provide the Target-Language Script

MkAnime reads the uploaded SRT or VTT as written. It does not automatically transcribe or translate the source video's speech.

The Dialogue Replaces the Source Audio

The generated dialogue track replaces the original audio. Music, ambience, and other background sounds are not preserved in this workflow.

Lip Sync Is a Separate Workflow

AI dubbing changes the audio track but does not alter mouth movement. Use the dedicated lip-sync workflow when the picture also needs to follow the new dialogue.

FAQ

AI Dubbing FAQ

01

What is AI dubbing?

AI dubbing uses generated speech to replace or add spoken dialogue in a video. In MkAnime, the uploaded SRT or VTT provides the words and timing, and the selected AI voice reads each cue.

02

Does MkAnime automatically translate the original video?

No. Prepare the target-language dialogue before uploading the subtitle file. The tool reads the supplied script as written and does not automatically translate or transcribe the source audio.

03

Are the uploaded subtitles burned into the video?

No. SRT and VTT cues are used to time the generated speech. They are not rendered as visible captions in the downloaded video.

04

Does AI dubbing preserve background sound or add lip sync?

No. The new dialogue replaces the source audio, so background sound is not preserved, and this tool does not change mouth movement. Lip sync is available as a separate workflow.
