Original Summary

I've been going through Kling 4.0 material lately, and a lot of write-ups credit 4.0 with things 3.0 already had. The usual three are 4K, native audio and multi-shot. The official docs show all three were there in the 3.0 era: native audio and Multi-Shot are in the 3.0 launch guide, and a 4K mode was added to the 3.0 series this April. So I lined up the official 3.0 and 4.0 docs side by side. As far as I can tell, the real changes in the full 4.0 model come down to a few things: the single-generation cap goes from 15s to 30s, up to 10 keyframes, up to 15 combined reference assets, plus what Kling describes as better handling of complex motion and big camera moves, and broader audio/language support. The short version first ("3.0" means the 3.0 series; the reference and editing parts mostly refer to 3.0 Omni): Area Kling 3.0 series Kling 4.0 (full) My read Single generation length 3–15s 3–30s The cap doubled; not every clip should max it out Timing / shot control First/last frame, Multi-Shot, Custom Multi-Shot Up to 10 keyframes Multi-shot isn't new; more anchor points on the timeline is Combined references Omni: up to 7 images/subjects without video; with video, 1 video + up to 4 images/subjects Up to 15 reference assets in total A total cap, not per-category quotas added up Resolution 720p, 1080p, later a 4K mode (not on every variant) 720p / 1080p / 4K 4K isn't new in 4.0 Dynamic range 8-bit SDR 10-bit HDR at 1080p/4K Officially marked coming soon Audio Native audio, multiple languages, lip-sync, Omni subject voice control Stereo, more languages "Better lip-sync" is Kling's claim; I haven't tested it Video editing 3.0 Omni already had reference-driven editing Richer native multimodal editing, larger input capacity Not the first version with editing Motion / camera Camera moves and related reference controls already existed Kling says complex motion and large camera moves are more stable No public success-rate data 1. What 30 seconds is actually good for Going from 15s to 30s sounds like a number doubling, but for anyone making clips the real difference is whether one complete action fits in a single generation. A lot of shots have a natural arc: the build-up, the action itself, someone's reaction, and the moment it settles. Squeezing all four into 15s is tight, so people split it into several generations and stitch them, and continuity at the seams becomes its own problem. A 30s window leaves more room to plan, so continuous product demos, a small single-scene story, a performance clip or one long camera move have a better chance of fitting in one pass. A few things are easy to overstate, though. 30s is a cap, so it doesn't mean every clip should be 30s. It doesn't mean you can skip editing, and it doesn't automatically mean fewer retries or lower cost. The official material has no numbers on that and I haven't run comparison tests, so the honest claim is just "more room to plan a shot." Also, the "multiple extensions up to 2 minutes" Kling men
