Real demo
One avatar video, a second language
Switch versions and turn the sound on. A dub alone changes the voice but not the mouth; a lip-sync pass in Avatar Talk fixes that.
- Original (English). The talking clip as generated.
- Spanish dub. Dubbed with Kenerate's dubbing tool: new language, same lips.
- Spanish + lip sync. VEED Lipsync 2 in Avatar Talk redraws the mouth to the Spanish audio.
All three are unedited outputs of Kenerate's tools.

Tips
Avatar videos people watch to the end
The engine does the lip sync; the script and the edit keep viewers watching.
Open with the point; the first sentence decides whether people stay.
Write for the ear: short sentences, one idea each.
Split long courses into chapters of a few minutes.
Pick 9:16 for Reels, Shorts and TikTok; 16:9 for YouTube and slides.
Add captions: many people watch with the sound off.
Dub first, then lip-sync the dubbed audio.

FAQ
AI avatar video generator — questions
7 questions
Is there a free AI avatar video generator?
Avatar Talk works on Kenerate's free plan with the sign-up credits, so you can generate avatar videos without paying first. How far the credits go depends on the engine, resolution and length; one-time credit packs, which don't expire, top them up. Kenerate's text-to-video models in the video studio need a credit pack.
Link to this answerHow long can an AI avatar video be?
Up to 10 minutes per clip with Kenerate Avatar, InfiniteTalk, Kling Avatar 1 Pro, SoulX FlashHead and HeyGen Presenters. For longer courses, split the script into chapters and join the clips in an editor.
Link to this answerWhat resolution do avatar videos come out in?
It depends on the engine: Kenerate Avatar renders 720p or 1080p, HeyGen Presenters 720p, 1080p or 4K, LTX Lipsync up to 1080p, and InfiniteTalk 480p or 720p. Some engines, such as OmniHuman 1.5, choose the size themselves.
Link to this answerCan I turn a script into an avatar video?
Yes, in two tools. Write the script in Voice Studio and generate the voice, then pick that take from History in Avatar Talk as the audio. The avatar speaks exactly the words in the script.
Link to this answerCan I make an avatar video in another language?
Yes. Generate the voice in the language you need, or dub a finished video with Kenerate's dubbing tool and then run a video lip-sync engine such as VEED Lipsync 2 so the mouth matches the new audio.
Link to this answerCan I add captions to an avatar video?
Yes. Open the finished video in Auto Subtitles, which transcribes the speech and burns timed captions into the picture in one of 10 styles, at 720p or 1080p.
Link to this answerHow is this different from an AI video generator?
An AI video generator invents the whole scene from a prompt and its own sound. An avatar video generator starts from a face and your audio, so the words and timing are exactly yours. For B-roll around the presenter, use the video studio's models.

The four parts of an avatar video
Every avatar video is a face, a voice, a performance and a frame. Avatar Talk takes care of the performance, the lip sync and movement; you decide the other three.
- Face: your portrait, a generated character or a stock presenter.
- Voice: a recording, a Voice Studio narration or a dubbed track.
- Performance: the engine plus an optional direction prompt.
- Frame: 16:9 or 9:16 presenters, or your image's own shape.
Photo engines vs video engines
The 19 photo engines generate the whole performance from a still image, which is why the face, head and body move. The 7 video engines start from footage that already exists and redraw only the mouth, or the face with Sync React-1, keeping the original camera work. Use photo engines to create an avatar video, video engines to re-voice or translate one.
Choosing resolution
720p is enough for social feeds and most course platforms. Choose 1080p on Kenerate Avatar for full-screen viewing, or HeyGen Presenters in 4K for large screens. Higher resolutions use more of your balance.

Free AI avatar video generator
Free to start: Avatar Talk runs on the free plan with sign-up credits, with no subscription. When they run out, one-time credit packs top them up.
