Kling Avatar V2 on AI Compare Hub

Kling Avatar V2 by KwaiVGI turns a single portrait image and an audio file into an expressive, lip-synced talking-avatar video. It works on realistic humans, cartoons, illustrations, and animals — and outputs up to 1080p at 48 fps in Pro mode. Video duration automatically matches the length of the audio you upload, so there's no separate duration parameter to set.

What you can create

• Talking presenters from a single photo

  Upload a portrait of yourself, a colleague, or a public figure (with permission), pair it with a recorded voiceover, and Kling Avatar V2 produces a lip-synced presenter video. Use it for sales explainers, internal training, customer FAQs, and personalized outreach.

• Voiced cartoons and illustrated characters

  Animate hand-drawn characters, mascots, and stylized portraits with the same lip-sync accuracy as photo-realistic avatars. Ideal for animated brand mascots, kids' content, comic-style storytelling, and indie-game promo material.

• Animal and creature avatars

  Kling Avatar V2 handles animal portraits and stylized creatures, mapping mouth movement and expression to your audio. Great for fun social content, mascot-driven announcements, and pet-account-style storytelling.

• Multilingual voiceovers from one portrait

  Reuse the same portrait with different audio tracks to produce translated or alternative-language versions of the same message. Each generation matches lip movement to the new audio while preserving the avatar's identity and framing.

Why creators choose Kling Avatar V2

• Just two inputs — image plus audio

  No motion-capture rigs, no green screens, no manual keyframing. A portrait image and an audio file are all that's required to produce a finished talking-avatar clip. Optional text prompt adds style, emotion, and camera framing direction.

• Expressive lip sync, not just mouth flapping

  Kling Avatar V2 generates eye blinks, brow movement, micro-expressions, and head motion that match the cadence and tone of the audio — producing avatars that read as alive rather than mechanical.

• Two quality tiers for any budget

  Standard mode (720p) costs 28 cr/sec for everyday social and outreach content. Pro mode (1080p, 48 fps) costs 50 cr/sec when you need broadcast-style quality. Pick the tier that matches the deliverable.

• Audio-driven duration with no manual trimming

  Output length matches the audio file exactly — no trimming, no silence padding, no need to guess a duration parameter. Upload a 15-second voiceover and you get a 15-second video. Upload a 90-second one and you get a 90-second one.

How to generate your first avatar video

1. Pick your portrait. Use a clear, front-facing portrait with a single subject. Realistic photos, illustrations, cartoons, and animal portraits all work. Avoid heavy occlusion (sunglasses, masks) for the best lip sync results.
2. Provide your audio. Upload an audio file (MP3, WAV, M4A, or AAC, max ~5 MB). You can also generate audio first using AI Compare Hub's Text-to-Speech feature and select it from your gallery. The output video duration matches the audio length.
3. Configure mode and prompt. Pick Standard (720p) or Pro (1080p, 48 fps). Optionally add a prompt to direct emotion, energy, or camera framing — e.g., "warm, smiling, looking directly at the camera." Generate and review.

Common questions

What is Kling Avatar V2?

Kling Avatar V2 is KwaiVGI's portrait-driven avatar animation model, available via the Replicate API. It turns a single image plus an audio file into an expressive, lip-synced talking-avatar video — supporting realistic humans, cartoons, illustrations, and animals, with output up to 1080p at 48 fps in Pro mode.

How is the video duration determined?

Output duration matches the length of the audio file you upload. There is no separate duration parameter — a 10-second audio file produces a 10-second video; a 60-second audio file produces a 60-second video.

What inputs are required?

A portrait image and an audio file are both required. An optional text prompt can refine the animation style, emotion, or camera framing — e.g., "calm and authoritative, slight head movement, warm lighting."

How much does Kling Avatar V2 cost in credits?

Standard mode (720p) costs 28 credits per second. Pro mode (1080p, 48 fps) costs 50 credits per second. A 15-second voiceover renders at ~420 credits in Standard or ~750 credits in Pro.

What audio formats are supported?

MP3, WAV, M4A, and AAC are supported. The audio file must be ≤ 5 MB. For longer voiceovers, compress the file or split into multiple shorter generations.

Can I generate the audio on AI Compare Hub first?

Yes — generate the voiceover with AI Compare Hub's Text-to-Speech tool first, then select the resulting audio from your gallery when configuring Kling Avatar V2. The two-step workflow lets you craft the script, pick a voice, and animate the portrait without leaving the platform.
