AI dubbing and voice changer

AI dubbing re-voices your video in another language. The voice changer keeps the language and swaps the voice. Both live in the editor and are paid for with credits.

Available on: AI dubbing: Starter and Pro. Voice changer: Free, Starter and Pro.

Before you start

• No plan includes credits. You buy credit packs separately, and they never expire. See Credits.
• Both tools work on videos up to 2 hours long.
• Both tools are in the editor. The AI Tools button works only when you open the editor from a video.
• The video needs audio. A recording made without a microphone cannot be dubbed.

Dub a video

1. In the sidebar, click My Library, then open the video.
2. In the Edit in Editor card, click Open in Editor. Zidi makes an edited copy of the video, and AI Tools work on that copy. See Edit a copy.
3. In the editor toolbar, click AI Tools, then open the AI Dubbing section.
4. Under Source Language, choose the language spoken in the video. The default is English.
5. Under Target Language, choose the new language. The default is Spanish.
6. Leave Clone original voices on to keep the sound of the original speakers in the new language. It is on by default.
7. Click Generate Dubbing. The button shows the cost in credits, with the note “20 credits per minute, rounded up”.

While it runs, the panel says “This usually takes 2–20 minutes. You can close this tab and come back — we'll pick up where we left off.” Zidi does not send an email or a notification when the dub is done. Come back to the editor to check.

When it is done, you see “Dubbing completed successfully!” and the button reads Dubbing Ready. If the editor is open at that moment, the dub is added to the timeline as an audio track. Otherwise, click Load to Timeline.

What you get

• One dub per video. It is an audio track on the editor timeline, next to your original audio.
• When you download the edited video, your original microphone audio is muted if the dubbed track is not muted. Downloading edited videos needs Starter or Pro.
• Viewers cannot switch between languages. There is one audio version per video.
• For recordings and edited copies, anyone who plays the video, including through its share link, can hear the dub instead of your voice as soon as it is ready. You do not need to save or download first. To go back to your voice, click Remove Dubbing.

Save your editor changes to keep the track on the timeline. See Video editor.

Dub into another language

To make a new dub, click Remove Dubbing, change the settings, then click Generate Dubbing again. The same applies if you change Clone original voices after a dub is ready.

Supported languages

AI dubbing supports exactly these 29 languages, as source or target. The picker shows each language in its own script, for example Español for Spanish.

• Arabic
• Bulgarian
• Chinese
• Croatian
• Czech
• Danish
• Dutch
• English
• Filipino
• Finnish
• French
• German
• Greek
• Hindi
• Indonesian
• Italian
• Japanese
• Korean
• Malay
• Polish
• Portuguese
• Romanian
• Russian
• Slovak
• Spanish
• Swedish
• Tamil
• Turkish
• Ukrainian

Any pair works as long as the source and target are different. Each list hides the language chosen in the other.

Who can dub

You need Starter or Pro, plus enough credits. The plan and the credits that count are those of the person who owns the video. This applies to every video, including videos shared to a Team Library.

On the Free plan with no credits, you see the Insufficient Credits dialog first. After you buy credits, dubbing still needs Starter or Pro.

While a dub is running

You cannot start a second dub for the same video while one is running. If a dub gets stuck, the video unlocks 60 minutes after the dub started.

If a dub fails, you see “Dubbing failed. Please try again.” A failed dub costs nothing. Click Generate Dubbing to try again.

Change the voice

Available on: Free, Starter and Pro (with credits)

1. Open the video in the editor, as in Dub a video.
2. Click AI Tools, then open the Voice Changer section. The voices load automatically. If they do not, click Load Voices.
3. Under Choose Voice, use Search voices… or the any, female and male filters. Click play on a voice to preview it.
4. Click a voice to select it.
5. Leave Remove background noise on, or turn it off. It is on by default.
6. Click Apply Voice. The button shows the cost in credits, with the note “10 credits per minute, rounded up”.

You see “Voice change initiated! Converting to [voice]” and later “Voice change completed!” If the editor is open when it finishes, the new voice is added to the timeline. Otherwise, click Load to Timeline. To try another voice, click Remove Voice and apply again.

As with dubbing, the new voice is stored on the copy you are editing, and your original video keeps its own audio. For recordings and edited copies, anyone who plays the video, including through its share link, can hear the new voice as soon as it is ready. To go back to your own voice, click Remove Voice.

Any plan can use the voice changer, including Free, as long as you have credits.

Credits are taken before the new voice is delivered. If Zidi cannot deliver it, the same credits are returned.

Credits

Every started minute counts as a full minute. A 61-second video costs 40 credits to dub and 20 credits to re-voice. The length comes from the video as stored in Zidi. On an edited copy, that is the original's full length, or the copy's own length if that is longer. On a recording you trimmed with Edit in Editor and saved, it is the full recorded length.

Both tools always use the credits of the person who owns the video. Sharing a video to a Team Library does not change that. Neither tool counts toward the daily AI limit.

If you do not have enough credits, the Insufficient Credits dialog shows Required, Available and Shortage. Click Add Credits to buy a pack, or View Plans to open Billing.
