Announced is not confirmed
Kling's own 4.0 overview lists 30-second clips, 10 keyframes and 4K output, and third-party coverage such as Morphic repeats those figures. Until the full model ships, nobody outside Kling can verify them: treat them as reported, not confirmed. The only Kling 4.0 tier anyone can run today is Flash, which tops out at 20 seconds and 720p.
Watch Kling 4.0 if…
Your shots need many fixed beats: ten keyframes let you pin a sequence of poses or product states and let the model fill the motion between them. Wait for the full release and test it before you plan production around it.
Watch Seedance 2.5 if…
Your work leans on references: up to 30 images, 10 video clips and 10 audio clips in one pass keep characters, products and voices steady across a 30-second take.
What to use on Imgo today
Seedance 2.0 is live in Imgo's video generator: up to 15 seconds per clip, image, video and audio references, and native audio. For a 30-second piece, plan two connected shots that share the same reference images, then compare takes side by side.
