Kling vs Seedance: the same shot in both

Kling is made by Kuaishou, and Seedance by Seed, ByteDance's AI lab. Both turn a photo into a short video with sound, and both are in Hook Studio's model menu. Most pages that compare them are spec tables, and some come from the makers' own apps. This one is a test: on November 14, 2026, we ran the same three shots through Kling 3, Kling 4, Seedance 2 and Seedance 2.5, and kept every take, including the ones that failed.

• Same start. Each shot began from one still we approved before any clip, so every model started from the same first frame.
• Same words. One prompt per shot, word for word the same for every model, in Hook Studio's organic style: filmed on a phone by someone who was there.
• Same length. 5 seconds. Kling 3 renders only at 1080p, so it ran at 1080p. The other three ran at 720p.
• Two checks. Hook Studio's realism check reads the frames and flags what looks fake, and the lip-sync check compares the mouth with the voice, sentence by sentence. Whether a clip did what the prompt asked is our own read of its frames.
• One take each. No retakes and no picking the best of three. A single take is a sample, not a verdict.

The people are AI people from Hook Studio's premade cast: Camila, Marco, and Nia. Every clip below starts on the still its shot was made from. The clips play muted: tap the speaker on a phone for sound.

Camila sits at a café table in Mexico City and says one line in the clip's own voice: no voice-over, no lip-sync pass after. We ran this shot on Kling 3, Kling 4, and Seedance 2.5. Hook Studio's model menu calls Seedance 2.5 "most natural acting", so it stood in for Seedance here. The prompt, word for word:

Seated at the café table, she is already talking to her friend across the table, calm and friendly, with a small natural nod; her hand stays near the cup. She says: "Same photo, same line, different AI model. Which one looks real?"

We made the same three clips in Spanish, from the same still, with the line "Misma foto, misma frase, otro modelo de IA. ¿Cuál se ve real?" The result held. Kling 3 passed again, though its voice ran 0.5 s ahead of the mouth in the last second. Kling 4 failed with Camila's eyes shut for about three seconds while she talked. Seedance 2.5 failed on a pucker with her eyes shut, and its voice ran 0.4 s ahead at the end. The Spanish takes are in the Spanish version of this post.

So two of three models turned a calm line into a performance, in both languages. Kling 4 still kept the mouth on the voice, and Seedance 2.5 drifted in both. Kling 3 is not immune either: in our flower shop guide, all four of its talking takes over-acted. Budget for a retake on any talking clip, whatever the model.

Marco pours coffee from a glass carafe into a green mug, then sets the carafe down. No speech. A pour tests two things at once: the hands, and the liquid. Every model got the same prompt:

He is already pouring: the coffee streams from the carafe into the green mug and the mug fills about halfway; then he sets the carafe down on the counter beside the mug. Calm, unhurried, no talking.

Kling 3, 1.5 s

Seedance 2, 4.8 s

Both Seedance takes got the liquid the prompt asked for, half a mug of black coffee. Kling 4 and Seedance 2.5 were the two takes we would post. The cheapest clip of the shot, Kling 3, made the strangest mistake: a person who was never in the still.

This shot tests direction: does the model do what the prompt says, in the order it says it? Nia stands in her living room with a white mug. The prompt asks for three actions, one after the other, in 5 seconds:

Three actions, in this order, starting at once: first she takes one sip from the white mug; then she steps toward the narrow wooden wall shelf at waist height and sets the mug down on it; then she turns back to the camera and waves with both hands, smiling. No talking.

The still

Kling 4, 4.8 s

All four models did the three actions in the right order, so the order was not where they differed. The room was. Every model rebuilt the shelf as a longer one with two straps once she stood at it, and the check failed only Kling 3 for it. Kling 4 repainted the art, and the check missed it. Whatever the model, put the last frame of a clip next to its still before you post it.

Fourteen takes: one per model per shot, with the talking shot in two languages. Each cell is the realism check's verdict. Seedance 2 sat out the talking shot.

No model won every shot. Kling 3 passed the talking line twice and failed both silent shots. Kling 4 and Seedance 2.5 did the opposite. On a sample this small, the pattern by shot type tells you more than the totals.

Prices are Hook Studio credits for one 5 second clip on November 14, 2026. A longer clip costs in proportion, and a still costs 11. Only Kling 3 costs more when the person speaks in the clip's own voice. At 1080p, Kling 3 is the cheapest model in the menu by a wide margin.

Seedance 2 Mini and Seedance 2 Fast are the cheap way to draft: 34 and 49 credits at 480p. Use them to check how a shot moves before you pay for the final. A draft of a Kling 3 clip runs on Seedance 2 Mini at 480p, a different model, so the final will not move the same way.

Kling 4 came out on October 15, 2026, and Seedance 2.5 on July 31, 2026. These are the makers' own specs:

In Hook Studio, every clip is 4 to 10 seconds and starts from one approved still, on every model. The reference limits matter when you use a model in its maker's app or API. Through the provider Hook Studio uses, the two Kling models take no reference files at all, and the Seedance models do.

On Artificial Analysis's image-to-video leaderboard, read on November 14, 2026, Seedance 2.5 ranked first, Seedance 2.0 third, and Kling 3.0 23rd. We did not find Kling 4 on it. That board ranks blind votes between short clips. It does not test lip sync, the order of actions, or price, which is what this test looked at.

• A person talking to the camera, in English or Spanish: start with Kling 3. It was the only model whose talking takes passed here, in both languages, at 143 credits with speech. Plan for a retake anyway.
• A product in someone's hands, with liquid or small details: Seedance 2.5 or Kling 4. Both passed the pour. Seedance 2.5 got the coffee right for 197 credits; Kling 4 costs 134.
• Several actions in a set order: all four did the order. Pick the one that keeps the room still: Seedance 2.5 was the cleanest, and Seedance 2 passed for 131.
• The lowest price at 1080p: Kling 3, 96 credits without speech. Check the edges of the frame for extra people and objects that change.
• One long take, or a lot of reference files: Kling 4 and Seedance 2.5 reach 30 seconds in their makers' apps, and Seedance 2.5 takes the most references.
• A cheap first look at the motion: Seedance 2 Mini or Seedance 2 Fast.

A reel does not have to stay on one model. In Hook Studio each clip runs on the model you pick for it, so a reel can open on a Kling 3 talking hook and cut to a Seedance product shot. To run this kind of test on your own shot, follow how to pick an AI video model.
