What to compare visually
For a fair A/B test, use the same scene and, where both modes allow it, the same first frame. Inspect motion continuity, character and object consistency, physics and contacts, camera behavior, temporal deformation, in-clip cuts and audio synchronization.
What to inspect with Kling 3.0
Multiple shots, reference-based characters and optional sound for scenes that need more than an attractive camera move.
Regular generation starts from text or a first frame with an optional last frame. Duration ranges from 3 to 15 seconds.
Multi-shot supports up to five scenes with individual prompts and durations. Their durations must add up to the total; a last-frame image is not used in this mode.
Cuts do not guarantee perfect continuity. Check clothing, hands, product placement and eye lines between shots.
4K increases output size; it does not fix misdirected action or anatomical mistakes.
What to inspect with Kling 4.0
A clip of up to 30 seconds from text and references or from a chain of keyframes: named characters, voice samples and exact frames.
Text and references: up to 10 reference photos and 5 videos, up to 7 characters (2–4 photos or one 3–8 second video clip each) and up to 3 voice samples. The Video sound switch applies only to reference videos.
Keyframes: a first frame, a last frame and up to 8 middle frames. The total number of frames depends on the duration and never exceeds 10.
The modes do not mix: Keyframes accepts no video, and characters and voices belong only to Text and references mode.
A hero photo must be at least 300 pixels on the short side; a video character needs at least 700 pixels and one continuous shot.
How to run a fair comparison
Fix the scene, the first frame (if both models accept one), the duration and the resolution.
Judge motion, not stills: faces, hands and objects should hold across the whole clip and at cuts.
If sound matters, listen to it separately: dialogue, effects and lip sync differ between models.
Price a finished clip, not a second: the per-second rate times your real duration, rounded up once.
Sources
Prices, availability and specifications come from the Mixer AI catalog. This is not an independent test: try both models on the same task before choosing.
Price, 1 s · 1080p: Kling 3.0 ≈ 13.43 coins · Pro, Kling 4.0 ≈ 18.22 coins · Reference. Kling 3.0 is cheaper. The total depends on your settings: the price of the chosen options is shown in the interface before you run.
How does Kling 3.0 differ from Kling 4.0?
Kling 3.0 — price, 1 s · 1080p: ≈ 13.43 coins · Pro; resolutions: 720p / 1080p / 4K; Multi-shot: Yes. Kling 4.0 — maximum duration: 30 s; input photos: up to 8; input videos: up to 5.
How should I compare Kling 3.0 and Kling 4.0 fairly?
Fix the scene, first frame, duration and resolution. Watch the motion across the whole clip and listen to the sound separately. Price the finished clip, not one second.
Are both models available in Mixer AI?
Yes. Both models are in the Mixer AI video catalog; the launch button on the page opens Canvas on a computer and the Studio on a phone. The page exists only for models in the current catalog.
Which model is better?
There is no single winner. First rule out the model that lacks the duration, first or last frame, sound or resolution you need, then compare clips on your own scene. The table highlights only measurable differences.
