Kling 4.0 hands-on: 10-bit HDR, 30s single-shot generation and 15 reference inputs for film-grade AI video
APPSO · wechat · 2026-09-29
Kuaishou's Kling 4.0 launches in October with a Flash tier already in limited preview. Hands-on testing highlights: stable camera work through fast action and complex moves, rare 10-bit HDR output at up to 4K that survives professional color grading, up to 30-second single-shot generation with accurate multilingual lip-sync and stereo audio, and up to 15 reference inputs (10 images + 5 videos) for controllable multi-subject generation. The review also shares prompt techniques: use pro camera-move vocabulary, lock visual tone via director-style references, and build an asset library with strict reference priority rules.
