Kling AI Avatar v2 Standard [image-to-video]
Kuaishou's Kling AI Avatar v2 Standard delivers audio-driven avatar animations at $0.0562 per second, transforming static images into talking characters synchronized to any audio input. Trading general video generation flexibility for specialized lip-sync precision, this model handles realistic humans, animals, cartoons, and stylized characters with audio-matched facial movements. Built for content creators who need consistent character performance without manual animation work.
Built for: Talking head videos | Character-driven content | Audio-synced presentations | Educational content
Audio-First Animation Architecture
Kling AI Avatar v2 Standard operates as a specialized image-to-video model that constrains generation around audio synchronization rather than open-ended video creation. Where general video models interpret text prompts for scene composition, this endpoint requires both a static image and audio file as mandatory inputs, using the audio waveform to drive facial animation timing and lip movements.
What this means for you:
- Simple dual-input API: Upload one reference image (JPG, PNG, WebP, GIF, AVIF) plus one audio file (MP3, OGG, WAV, M4A, AAC) to generate synchronized avatar videos
- Character consistency: The model preserves the exact appearance, style, and visual characteristics of your input image while animating only facial features and subtle head movements
- Audio-driven timing: Video duration automatically matches your audio length with no manual configuration required
- Optional prompt refinement: Include text prompts to guide subtle aspects of the animation, though audio synchronization remains the primary driver
Performance That Scales
Kling AI Avatar v2 Standard positions as the cost-effective tier in Kuaishou's avatar generation lineup, with per-second pricing that scales linearly with audio duration.
| Metric | Result | Context |
|---|---|---|
| Cost per Second | $0.0562 | Approximately 17.8 seconds of avatar video per $1.00 on fal |
| Pro Tier Cost | $0.115/second | Kling AI Avatar v2 Pro for higher fidelity |
| Input Requirements | Image + Audio (mandatory) | Optional text prompt for refinement |
| Output Duration | Matches audio length | Video automatically scaled to audio file duration |

How It Stacks Up
Kling AI Avatar v2 Pro – Kling AI Avatar v2 Standard delivers the same audio-driven avatar animation at $0.0562/second versus Pro's $0.115/second. The Pro tier offers enhanced facial detail and smoother lip-sync precision for professional productions where output quality justifies the 2x cost premium.
Kling 2.5 Turbo Pro Image-to-Video – Kling AI Avatar v2 Standard trades open-ended scene control for specialized lip-sync precision, making it ideal for talking head content. Kling 2.5 Turbo Pro offers prompt-driven video generation with camera movement control for general image-to-video transformations where audio synchronization isn't required.
Kling 2.1 Master Image-to-Video – Kling AI Avatar v2 Standard constrains generation around audio input for consistent character performance at $0.0562/second. Kling 2.1 Master emphasizes maximum quality and cinematic motion at $1.40 for 5 seconds ($0.28/additional second) for high-fidelity general video generation.
Argil Avatars Audio-to-Video – Kling AI Avatar v2 Standard supports custom image input for any character style at $0.0562/second. Argil Avatars uses pre-trained avatar templates at $0.02/second for faster, lower-cost generation when custom character appearance isn't required.
