What AI Lipsync can do

Portraits

Any portrait, alive in seconds

Upload a single static portrait and 7ART turns it into a talking video. The face stays in place, the mouth moves to the audio, the eyes blink, the head shifts naturally. Works on any clear face — photographs, illustrations, AI generations, even paintings.

Artist

Your character, talking

Pick any image you have already generated — including a frame of a saved 7ART artist — straight from your library, and that becomes the portrait. The face stays consistent across clips because it is the same source image every time, which is what makes a recurring character deliver dialogue scene after scene.

Audio sources

Three ways to bring the audio

Upload an audio file, record straight from your microphone, or pick a clip you already generated in 7ART Voice — speech, dialogue or sound effect — from the Voice picker. Nothing leaves the studio, so a script you voiced in Text-to-Speech is two clicks from a finished talking video.

Multilingual

No language setting to pick

The engines sync to the audio itself rather than to a transcript, so there is no language field in the form — use a clip in whatever language you recorded it and generate. Results vary by clip; clear, close-miked speech syncs best.

Quality

Up to 1080p, up to five minutes

Kling Avatar Standard renders 720p at 8 credits per second; Kling Avatar Pro renders 1080p and accepts audio up to 5 minutes. Omnihuman 1.5 and HeyGen Avatar IV also offer 720p or 1080p, capped at 60 seconds. You are billed on the measured length of the audio you supply, not on an estimate.

Expression

More than a moving mouth

The avatar engines animate the head and face, not the lips alone — blinks, small head movement, expression that tracks the delivery. Kling Avatar Pro at 1080p holds up best on close-ups; Omnihuman 1.5 and HeyGen Avatar IV are there when you want a different look.

Frequently asked questions

• What is AI lipsync?

  AI lipsync animates a still portrait — or an existing video — so the mouth matches an audio track you supply. On 7ART you pick the face, pick the audio, and the studio returns a video of that face speaking. You choose the engine: Kling AI Avatar Standard (720p) or Pro (1080p), Volcengine video-to-video lip sync, Omnihuman 1.5, or HeyGen Avatar IV.

• Is 7ART free to try?

  You can create a free account and generate with your welcome credits, no card required. One thing to know up front: downloading files requires a paid plan — a free account can generate and preview, not export. Lipsync is billed per second of the audio you supply: 8 credits/second on Kling Avatar Standard and Volcengine, 16 on Kling Avatar Pro, 20 on HeyGen Avatar IV, 27 on Omnihuman 1.5. Current plans are on our pricing page.

• What is the best AI lipsync tool?

  The best lipsync tool depends on what you're making. Sync Labs (sync.so) leads on API-based applications and developer tooling. HeyGen focuses on corporate avatar use cases. Hedra is strong on character-driven content. 7ART's advantage is integration: lipsync works with your AI artist, your TTS-generated voice, your generated images, and your music — all in one workspace, one subscription.

• Can I use my AI artist with lipsync?

  Yes, by way of your library. Generate or open a portrait of your saved artist, then in Lipsync choose 'From library' and pick that frame. Because it is the same source image every time, the face stays consistent across clips — the same character delivering dialogue across a whole run of scenes. There is no separate artist dropdown inside Lipsync today; you select the portrait.

• Can I use a real person's photo?

  Only with their explicit consent. 7ART prohibits creating lipsync videos that impersonate identifiable real people without permission, including public figures, celebrities, and other users. You can use your own photo or someone who has given written consent. Misuse leads to account termination.

• How long can the lipsynced video be?

  Up to 5 minutes on Kling AI Avatar Pro. The other four engines — Kling AI Avatar Standard, Volcengine, Omnihuman 1.5 and HeyGen Avatar IV — cap at 60 seconds. The limit applies to the audio you supply: we measure its real length, bill on that, and refuse anything over the engine's cap before charging you. For longer pieces, generate in segments and cut them together.

• What languages does lipsync support?

  There is no language setting. The engines sync to the audio itself rather than to a transcript, so a clip you recorded in any language can be used as-is. We do not benchmark per-language accuracy, so test a short clip in your language before committing to a long take.

• Can I generate the voice and sync it in one workflow?

  Almost. Lipsync takes audio three ways: upload a file, record from your microphone, or pick something you already generated in 7ART Voice. That last one is the fast path — write the script in Voice, generate the speech, then open Lipsync and choose it from the Voice picker. Two sections of the same studio, one credit balance — but the speech is generated in Voice, not inside the Lipsync form.

• Can I use lipsync videos commercially?

  Yes. 7ART's Terms permit personal and commercial use of the content you generate, subject to those Terms, applicable law, and any rights or restrictions imposed by the underlying model providers — and subject to the consent rules above for any real person depicted. Note that downloading the finished file requires a paid plan.

• How does 7ART lipsync compare to HeyGen and Sync Labs?

  HeyGen specialises in corporate avatar content with prebuilt avatar libraries; Sync Labs (sync.so) focuses on a developer API. 7ART is a studio rather than a point tool: you bring your own face instead of picking from a stock library, and the portrait, voice, music and video all live in one workspace on one credit balance. You also pick the engine per job — including HeyGen Avatar IV, which we offer alongside Kling AI Avatar, Volcengine and Omnihuman 1.5.
