FAQ
Which AI video generator is best in 2026?
Hailuo 2.3 is strong for cinematic realism and physics, while Kling is strong for human motion. For synchronized audio, choose a currently available native-audio model such as Seedance. The right choice depends on your use case.
How long can AI-generated video clips be in 2026?
Current frontier models commonly generate short clips. For longer videos, chain clips using the same seed and assemble them in an editor.
