Why Choose LongCat Avatar?
Solving the common challenges in AI avatar generation: identity drift, limited duration, and unnatural stiffness.
01No More Identity Drift
Many avatar models lose the subject's likeness over time. LongCat Avatar employs a unique "Identity-Conserved" approach, ensuring that the face you upload is exactly the face you get in every frame of the video, whether it's 10 seconds or 10 minutes long.
02Disentangled Motion
We separate facial expressions, head pose, and lip-syncing into distinct control streams. This results in natural, non-repetitive movement. The avatar can nod, tilt its head, and express emotions naturally while maintaining perfect lip synchronization with the audio.
03Long-Form Stability
Designed for real-world applications like virtual teaching and storytelling. LongCat Avatar supports generating long videos without quality degradation. Our "Cross-Chunk Consistency" technology visual noise and jump cuts between segments.
04Production Ready
Output videos at up to 720p resolution with standard aspect ratios (16:9, 9:16). Whether for social media shorts or professional presentations, the quality meets the demands of modern content creation.
Frequently Asked Questions
What do I need to create a video?
Just one clear, front-facing image of a person (or character) and an audio file (speech or song). The AI does the rest.
Does it support other languages?
Yes! Since the model is audio-driven, it syncs lips to the sound regardless of the language. It works with English, Spanish, Chinese, Japanese, and more.
Can I use this for commercial projects?
Yes, the generated videos are suitable for commercial use, including advertisements, educational content, and social media marketing.
How long does generation take?
It depends on the audio length, but LongCat Avatar is optimized for speed. A 10-second video typically generates in under a minute.
