Made with this app
How it works
Kling Avatar v2 is a lip sync app powered by Kuaishou AI that animates a still photo to match any audio track you provide, up to 60 seconds long, with precise audio-visual synchronization. Unlike tools limited to human faces, it works equally well with realistic portraits, cartoon characters, and animal subjects. Creators, educators, marketers, and storytellers who need a talking character that falls outside the standard human-portrait mold will find it the most flexible option in the Arteza avatar lineup.

What you can make
Animated Mascot Videos
Brands that use an illustrated or animal mascot can upload the character art, attach a voiceover, and receive a fully lip-synced MP4 at up to 1080p. The result fits product announcements, social ads, or onboarding flows without requiring a human presenter on screen.
Children's Storytelling Content
Educators and authors can bring cartoon animal or storybook characters to life with narration or character dialogue. Because Kling Avatar v2 handles non-human face shapes, a talking fox or illustrated dragon stays convincingly in sync throughout a scene up to 60 seconds long.
Multilingual Character Localization
Swap the audio track for a dubbed recording in another language and regenerate. The model re-syncs mouth movement to the new audio, so a single character illustration can address audiences in multiple languages without redesigning the asset or shooting new footage.
Social Media Personality Clips
Creators running avatar-based channels can animate a consistent illustrated persona to deliver commentary, reactions, or announcements. The 1080p output and precise sync keep the character credible across Instagram Reels, TikTok, and YouTube Shorts formats.
Game and Comic Character Demos
Game developers or comic artists can produce a short voiced teaser using concept art before any full animation is built. Uploading a character sheet image with a scripted audio line yields a shareable MP4 that communicates the character's voice and personality to collaborators or backers.

Tips for better results
Use Clean, Forward-Facing Images
Kling Avatar v2 performs best when the character's mouth area is clearly visible and faces roughly toward the camera. Extreme side profiles or heavy occlusion around the mouth reduce sync accuracy, so choose or crop your source image accordingly.
Match Audio Clarity to Character
The model drives lip movement directly from your audio, so a clear, well-recorded track with minimal background noise produces tighter sync. For cartoon or animal characters, crisp consonants in the recording are especially important because the mouth shapes are more stylized.
Plan for the 60-Second Limit
The maximum audio length is 60 seconds per generation. For longer scripts, split the recording into segments and generate each separately. This also lets you fine-tune pacing or swap a single segment without regenerating the entire piece.
Export at Full Resolution
Output is delivered as an MP4 at up to 1080p. If you intend to embed the video in a larger production or reuse the character across formats, download the highest resolution available to preserve quality through any downstream compression.
When to choose this app
Choose Kling Avatar v2 when your subject is a cartoon, animal, or stylized character rather than a standard human portrait. SadTalker focuses on budget avatar generation from photo and audio but does not specify multi-character-type support. AI Talking Photo gives a single photo a line to say and a voice to say it in, making it a quick single-line tool rather than a versatile multi-character pipeline. Kling Avatar v2 fills the gap by combining precise lip sync, broad character compatibility, and up to 60 seconds of synchronized output in one app.
Frequently asked questions
What types of characters work with Kling Avatar v2?
The model is designed to handle realistic human photos, cartoon illustrations, and animal characters. As long as the character has a discernible mouth region in the source image, the lip sync engine can interpret the face shape and animate it to match your audio.
Can I use an illustrated or drawn image rather than a photograph?
Yes. Cartoon Support is a declared feature, meaning illustrated faces and stylized artwork are explicitly within the model's scope. This sets it apart from avatar tools optimized only for photorealistic human faces.
What audio formats and lengths are supported?
The app accepts an audio file paired with your image. The audio limit is 60 seconds per generation. Keeping your recording within that window ensures the full clip is processed and synced without truncation.
What does the output file look like?
Kling Avatar v2 delivers an MP4 video at up to 1080p resolution. The file contains the animated character with mouth movement synchronized to your audio track, ready to upload, embed, or edit in a video production workflow.
How do I get the best lip sync accuracy for an animal character?
Use a source image where the animal's mouth is clearly visible and reasonably centered in the frame. Pair it with audio that has clean diction and minimal noise. The model maps phonemes to mouth shapes, so distinct speech sounds produce more readable movement even on non-human faces.
Is there a way to produce content longer than 60 seconds?
The per-generation audio limit is 60 seconds. To produce a longer piece, divide your script into segments of 60 seconds or less, generate each segment separately, then join the resulting MP4 files in any standard video editor to create a seamless longer video.
Which AI model powers this app?
This app runs on Kling Avatar v2, available through Arteza with no separate account or setup.
Can I use the results commercially?
Yes. Content you generate is yours to use, subject to our content licenses.
How long does a generation take?
Most generations finish in under a minute, and you can watch progress live in the gallery.
