What do creator tests say Kling 4.0 does at launch, and which headline claims are not yet available?

Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. Two Mikkel Lassalle videos (2026-10-20 promotional showcase linking kling.ai; 2026-10-22 Artlist-affiliate test). Claims: generations up to 30 s at up to 1080p; multiple keyframes (Artlist video: up to 10) to fix states along a long shot; omni/multi-reference (Artlist: up to 15 image+video references, matching fal schema 10 images + 5 videos in C3-B388-01); stereo audio with lip-sync and dialogue in nine languages; much better in-video text, emoji and logo rendering; 21:9 output; Kling 4.0 Flash up to 20 s at 720p. The first video's TITLE advertises "10-Bit HDR, 4K" but its narration says Kling 4.0 "will also be able to support 10 bit HDR, 4K ... and video extension" once officially available, so HDR/4K were not shown. Creator tips: a start-frame image worked better than a character sheet for dialogue scenes; Kling 4.0 strong for pack shots, typography and animated lyric/graphic scenes; weaker on dynamic motion, complex camera moves and premium VFX, where he prefers Seedance 2.5. Price signal on Artlist: a 15 s 1080p generation cost 4,125 credits for Kling 4.0 vs 15,000 for Seedance 2.5 (~3.6x). Curator qualifications: Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. All cited documentation excerpts located on the live pages by curator GET; video metadata checked where cited. Creator video (auto-caption transcript excerpts read by discovery; promotional/affiliate); not curator-verified beyond video metadata. Limitations: Sponsored/affiliate context; single creator; auto-captions; outputs not visually inspected; Artlist credit-to-dollar rate not captured. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
