You have a photo of a face and a voice recording. Kling Avatar V2 turns those two files into a video of that face speaking those words — lip movements matched frame by frame, head moving the way a person's head moves when they talk.
That's the whole product. No timeline, no rigging, no 3D model. Upload two files, get a finished avatar back.
This guide covers what Kling Avatar V2 actually does, what it costs in credits, what your inputs need to look like, and — the part most guides skip — the specific conditions under which it produces something unusable. Last updated July 2026.
TL;DR — Kling Avatar V2 in one box
- What it takes: one front-facing portrait (JPG/PNG, max 10MB, min 300px) plus one audio file (MP3/WAV/M4A/AAC, max 5MB).
- What it returns: a talking video whose length automatically matches your audio. Standard mode outputs 720p; Pro outputs 1080p at 48fps.
- What it costs: 10 credits per second in Standard, 20/s in Pro. A 5-second clip is 50 credits — about $0.40 on an annual plan. That is the lowest per-second rate on the platform, matched only by Kling 2.6 Motion Control.
- It is audio-driven, not text-driven. You supply the voice. Kling Avatar V2 does not generate speech.
- Best lip sync: English and Chinese audio. Other languages work with slightly less precise phoneme matching.

What Kling Avatar V2 actually does
Kling Avatar V2 is an audio-driven portrait animation model. It takes a still image of a face and an audio track, then animates the face to match the speech — consonants, vowels, pauses, and emphasis all show up in the mouth movement.
The distinction that trips people up: Kling Avatar V2 does not write or speak your script. It is not a text-to-speech tool with a face attached. You bring the voice — recorded yourself, cloned elsewhere, or synthesized in another tool — and Kling Avatar V2 handles the visual half.
Beyond the mouth, Kling Avatar V2 generates the small motions that make a talking head read as human: slight nods, head tilts, micro-movements timed to conversational rhythm. Facial expression shifts with the tone of the speech. You can push this further with an optional text prompt — something like "nodding while speaking, friendly expression, slight head tilt" — to steer gesture and camera behavior on top of the audio-driven animation.
Kling Avatar V2 is not limited to photographs of real people. Kling Avatar V2 animates illustrated characters, anime faces, 3D renders, and stylized artwork, holding lip-sync quality across all of them. A hand-drawn mascot works as well as a headshot.
What you need before your first Kling Avatar V2 render
Two files. Kling Avatar V2 failure modes almost always trace back to one of them.
The portrait. JPG or PNG, 10MB ceiling, 300px floor. What Kling Avatar V2 wants is a clear, front-facing face, well lit, fully visible. Heavy occlusion is the enemy — a hand across the chin, a microphone in front of the mouth, hair over half the face, sunglasses. The mouth region especially needs to be unobstructed, because that's the region being rewritten.
The audio. MP3, WAV, M4A, or AAC, 5MB ceiling. Clean speech, minimal background noise, consistent volume. That 5MB limit is tighter than it looks: CD-quality WAV runs roughly 10MB per minute, so it caps out around 30 seconds — while a 128kbps MP3 fits several minutes in the same 5MB. Export long scripts as MP3 rather than fighting the cap.
Your output length is decided entirely by the audio. Upload a 10-second voiceover and Kling Avatar V2 returns a 10-second video — no trimming, no manual sync, no timeline. This is also how your bill is decided, which brings us to cost.
What a Kling Avatar V2 video costs
Kling Avatar V2 bills per second of output: 10 credits per second in Standard mode, 20 per second in Pro. Since output length equals audio length, you can price a job before you make it — read the duration off your audio file and multiply.
Kling Avatar V2 credit cost by audio length, in credits and dollars at both the credit-pack rate (~$0.0135/credit) and the annual-plan rate (~$0.008/credit).
Worth internalizing: a 30-second avatar video costs 300 credits in Standard — about $2.40 on an annual plan, or $4.05 buying credits outright. A full minute runs 600 credits.
For comparison, a five-second clip on Kling 3.0 with native audio costs 250 credits. You can generate nearly a minute of Kling Avatar V2 footage for the price of five seconds of flagship video. If your content is a person talking to camera, this is not a close call — Kling Avatar V2 is the cheapest way to make it, by a wide margin.
Standard versus Pro is a straight doubling: 10/s against 20/s. Pro buys 1080p at 48fps and more refined facial expression. The 48fps half is underrated — most video is 24 or 30fps, and the higher frame rate is what keeps fast mouth movement from looking choppy. Test scripts in Standard; render the keeper avatar in Pro.
Full plan and credit-pack pricing lives on the pricing page, and the credit system itself is broken down in the Kling AI pricing guide.
When Kling Avatar V2 breaks
Every Kling Avatar V2 guide lists the features. Here is the other half — where you will not like the result. Knowing these up front saves more credits than any optimization tip.
Obstructed or angled faces. Kling Avatar V2 needs to see the face it's animating. Profile shots, three-quarter angles with the far eye hidden, anything covering the mouth — these degrade lip sync badly or produce visible warping around the jaw.
Noisy or uneven audio. Lip sync is derived from the speech signal. Background music, room echo, two people talking over each other, or volume that swings between a whisper and a shout all give Kling Avatar V2 an unclear signal, and the mouth movement drifts out of step.
Languages other than English and Chinese. Multi-language lip sync is supported, but English and Chinese are the most accurate. Other languages come with reduced phoneme-level precision — usually acceptable, occasionally noticeable on close-ups where individual consonants are readable.
Full-body or multi-person shots. Kling Avatar V2 is a portrait model. A group photo or a wide shot with a small face gives Kling Avatar V2 too little facial detail to work with. Crop to a head-and-shoulders frame first.
Anything needing body language. Kling Avatar V2 animates the face and head. It is not going to give you gesturing hands or someone walking across a room. If your script depends on physical action, this is the wrong model — reach for a full video model instead.
The honest summary: Kling Avatar V2 is excellent at a narrow job. A clear portrait plus clean speech gives an avatar that holds up at full size. Push it outside that envelope and quality falls off fast.
Kling Avatar V2 vs the other ways to get lip sync
The platform offers more than one path to a talking mouth, and picking wrong costs real credits. Kling Avatar V2 is the right answer for a narrower set of jobs than people assume.
Use Kling Avatar V2 when you're starting from a still image and you already have the audio. Spokesperson clips, talking-head explainers, animated mascots, narrated product intros, multilingual avatar content built from one portrait.
Use a full video model when the shot needs a body, a scene, or camera work — anything where the face is one element rather than the entire frame.
The broader comparison of lip-sync approaches, including which model to use for which kind of footage, is covered in the Kling lip sync guide. Model specs and sample output live on the Kling Avatar V2 model page.
Getting a good Kling Avatar V2 result on the first try
Four things, in order of how much they matter:
- Crop tight before you upload. Head and shoulders, face centered, eyes and mouth clearly visible. This single step fixes most bad avatar output.
- Clean the audio first. Strip background music, normalize the volume, cut dead air at the start. Kling Avatar V2 reads the speech signal directly, so a cleaner signal is a cleaner mouth.
- Test in Standard, deliver in Pro. Prove the script and portrait work at 10 credits/second, then re-run at 20.
- Use the prompt field for intent, not description. "Friendly, slight nod at pauses" steers the animation. Re-describing what's already in the photo does nothing.
FAQ
What is Kling Avatar V2?
Kling Avatar V2 is an audio-driven AI model that animates a still portrait into a talking video. You upload one face image and one audio file, and Kling Avatar V2 generates frame-accurate lip movements, natural head motion, and matching facial expressions. Output is 720p in Standard mode and 1080p at 48fps in Pro mode.
How much does Kling Avatar V2 cost?
10 credits per second of video in Standard mode and 20 credits per second in Pro. Because the output length matches your audio length, a 5-second clip costs 50 credits (about $0.40 on an annual plan), 30 seconds costs 300 credits, and a full minute costs 600 credits. That is the lowest per-second video rate on the platform, matched only by Kling 2.6 Motion Control at 720p.
Does Kling Avatar V2 generate the voice too?
No. Kling Avatar V2 is audio-driven, not text-driven — you supply the audio file and Kling Avatar V2 animates the face to match. Record the voice yourself or generate it in a separate text-to-speech tool, then upload it as MP3, WAV, M4A, or AAC under 5MB.
What image works best with Kling Avatar V2?
A clear, front-facing portrait is what every good avatar starts from, — well lit, full face visible, nothing covering the mouth. JPG or PNG, under 10MB, at least 300px. Crop to head and shoulders before uploading — profile angles, heavy occlusion, and small faces in wide shots all reduce lip-sync accuracy.
Can Kling Avatar V2 animate cartoons and anime characters?
Yes. Kling Avatar V2 handles realistic photos, illustrated characters, anime faces, 3D renders, and stylized artwork, maintaining lip-sync quality across all of them. The same requirements apply — the character should be front-facing with a clearly visible mouth.
Which languages does Kling Avatar V2 support?
Lip sync works across multiple languages, with English and Chinese producing the most accurate results. Other languages are supported at slightly reduced phoneme-level precision, which is usually fine at normal viewing size and occasionally visible in close-ups.
How long can a Kling Avatar V2 video be?
A Kling Avatar V2 video matches your audio file exactly, so the practical limit is the 5MB audio cap rather than a fixed duration. Since CD-quality WAV runs about 10MB per minute and a 128kbps MP3 about 1MB, exporting speech as MP3 buys you minutes of runtime where WAV gives you roughly 30 seconds.
