Kling 3.0 (Kuaishou) and Seedance 2.0 (ByteDance) are the two video models people weigh most often. We ran the same four prompts on both, three of them vertical, and judged each pair from the clips themselves. Both run on Affogato from one credit balance, so the real question is which one to use for a given shot.
Many projects use both: Seedance 2.0 for the close-ups where someone has to act, Kling 3.0 for the wides and camera moves around them, cut together in the Video Editor. Both draw from the same credits.
Each pair was generated from the exact prompt shown, unedited, at each model's default settings with sound on. Press “Hear it” to listen to one side.
Test 1 · Acting
Seedance 2.0 won this run
Seedance plays the whole arc: the chin trembles, tears run, and she breaks into a smile through them, as the prompt asks. Kling's reading is calm and frontal and the emotion stays small, although both deliver the whispered line on cue.
Close-up, vertical frame: a woman in her sixties sits by a rain-streaked window reading a handwritten letter. Her eyes move along the lines, her lips press together, then her chin trembles as tears well up. She lowers the letter, exhales a shaky laugh and whispers, "you remembered." She smiles through the tears. Soft grey window light, shallow depth of field, the camera holds almost still with a very slow push-in. Sound: rain on glass, paper rustling, her quiet breath.
Test 2 · Physics
Tie in this run
Both land a believable kickflip: the board turns once under the feet and dust kicks up on the landing. Kling sticks closer to the prompt with the tilt-up camera and a flat landing; Seedance looks more like real phone footage but adds a grind on the ledge nobody asked for.
Low-angle handheld shot at street level: an adult skateboarder in a grey hoodie rolls toward a concrete ledge in an empty plaza at golden hour. He pops a kickflip, the board spins once beneath his feet, he catches it and lands with knees bent, wheels clacking hard on the concrete. The camera tilts up to follow the jump, then settles as he rolls away. Long shadows, dust kicked up on landing. Sound: wheel roll, the snap of the tail, the landing clack.
Test 3 · Multi-shot consistency
Seedance 2.0 won this run
Seedance hits all three beats, ending on the close-up smile the prompt asks for, and keeps the same face and coat in every shot. Kling's bridge crossing reads better in the wide shot, but its close-up has no clear smile and the cafe signs come out as garbled text.
A woman in a bright yellow raincoat cycles through a wet European side street at dusk. Begin with a wide shot from across the canal as she crosses a small stone bridge, then cut to a tracking side profile as she pedals past glowing cafe windows, then a close-up as she brakes and smiles at something off-screen. The same woman, same raincoat, in every shot. Puddles splash under the tyres. Sound: rain patter, bike chain, soft cafe music spilling out.
Test 4 · Dialogue and shot list
Kling 3.0 won this run
Both speak both lines clearly and in order. Kling follows the shot list beat for beat (flour on the apron, hands wiped on a cloth, the loaf slid across and picked up), while Seedance's light is lovelier but it skips the hand-wipe and the hand-over.
A small bakery at dawn, three shots. Shot one, medium shot: the baker, a woman in a flour-dusted apron, wipes her hands and says warmly, "first batch is out." Shot two, reverse shot over her shoulder: the courier at the counter, tired but smiling, immediately replies, "then i'm first in line." Shot three, close-up: she slides a steaming loaf across the counter and the crust crackles as he picks it up. Warm window light, ambient oven hum and quiet street noise.

Open with Seedance 2.0Prices are each model's default: Kling 3.0 Pro renders 1080p with sound (sound off is cheaper); Seedance 2.0 renders 720p with sound at the same price either way, and 1080p costs about twice as much. Credits are read from the live catalog; the Standard plan ($24/month) includes 2,000 credits. At 10 seconds, Kling 3.0 Pro costs 45% less.
Seedance 2.0. Faces move with intent, and dialogue, breathing and room tone come out of the same pass. Keep each spoken line short.
Kling 3.0. Give each shot its own line and it tends to do all of them, in order, with the same people across the cuts.
Seedance 2.0 Reference to Video takes up to nine images and keeps the product recognisable. Kling 3.0 animates a single start image; use Kling O3 when you need references on the Kling side.
Kling 3.0. It follows named camera moves closely, and its 4K tier renders true 4K frames for the take you publish.
Kling 3.0 Turbo or Seedance 2.0 Fast. Find the shot on the cheaper tier, then re-run the winning prompt on the full model.
Kling 3.0. Since March 2026 ByteDance blocks most reference images that show real faces, so Seedance refuses many of those runs.

Neither wins every shot. In our four same-prompt tests Seedance 2.0 won on acting and on a three-shot sequence, Kling 3.0 won on following a detailed shot list, and a kickflip was a tie. Kling is also cheaper for the same length; Seedance is the better pick when a face has to perform.
Kling 3.0 Pro costs less for the same clip length at its default 1080p, and less again with sound off. The cost cards above are read from the live catalog for a ten-second clip.
Both render 9:16 natively. For talking-to-camera and reaction clips, Seedance 2.0 looked more natural in our tests; for action shots where the camera has to move a certain way, Kling 3.0 is easier to direct.
Yes. Both generate dialogue, effects and ambience with the picture, and both spoke every scripted line in our tests. On Kling, turning sound off lowers the price; on Seedance it does not.
Yes. Both run in Video Studio from one credit balance, everything lands in the same library, and the Video Editor can cut clips from both into one timeline.
Seedance 2.5 is on Affogato: it runs up to 30 seconds but costs more per second. Kling 4.0 was released in October 2026 and is not on Affogato yet; this page will be re-tested when it is.
Each prompt was run once on Kling 3.0 Pro and once on Seedance 2.0 at their default settings with sound on, and the clips are shown unedited. One run per model is a sample, not a benchmark, so run your own shot on both before committing to one.
Both models run in Video Studio on one credit balance. Open either one, paste the same prompt, and keep the better take.
