Which AI video model to use: one for each job, tested on the same shots

There is no single best AI video model. There is a best model for each job. On November 14, 2026, we ran the same three shots on four video models in Hook Studio: a woman talking to a friend across a café table, a man pouring coffee, and a woman doing three things in a set order. Kling 3 made the only talking takes of the four that passed our realism check. Seedance 2.5 poured the most believable coffee and did the three steps most cleanly. No model won every shot. Later that day, Hook Studio added Google's Gemini Omni 1.2 Flash, and we ran the same shots on it: its talking takes passed too, in English and in Spanish, for 60 credits each.

Each clip is 5 seconds, made from the same approved still with the same prompt. We made one take per model per shot, so read the results as a sample, not a verdict. The people are AI people from Hook Studio's premade cast. This page shows one clip per job. For all 14 clips side by side, and how to run the same test on your own shot, see how to pick an AI video model.

A top-up is $1 for 100 credits, so a 5 second Kling 3 clip with speech is about $1.43. Kling 3 renders at 1080p only; the other models ran at 720p.

Talking to camera: Kling 3 or Gemini Omni

Camila says one line to a friend across a café table: "Same photo, same line, different AI model. Which one looks real?" We asked for calm and friendly. Kling 3's takes passed the realism check in English and in Spanish. In English, the lip-sync check found her mouth matched the voice in both sentences. In Spanish, the voice ran 0.5 seconds ahead of her mouth in the last second. Kling lists Spanish among the five languages its lip sync supports.

Kling 4 and Seedance 2.5 over-acted the line. Kling 4 kept her mouth in sync, but swept her hand across the table and knit her brow into a skeptical face. In Spanish it kept her eyes shut for about three seconds while she talked. Seedance 2.5 made round "oh" mouths and pursed lips in both languages, and its voice drifted ahead of her mouth in both.

Google's Gemini Omni 1.2 Flash joined Hook Studio later the same day, so we ran the same still and prompt on it. Both takes passed the realism check, and the lip-sync check matched her mouth to the voice in English and in Spanish. It costs 60 credits for 5 seconds at 720p, with or without speech. One take per language, like the rest. For Kling against Google's models, see Kling vs Veo.

Products and liquids: Seedance 2.5

Marco pours coffee from a glass carafe into a green mug, then sets the carafe down. Seedance 2.5 and Kling 4 both passed the realism check. Seedance 2.5 left the mug half full of black coffee, the way we asked. Kling 4's carafe barely emptied. Seedance 2 poured the best coffee of the four, then pushed the camera in until his face was cut off above the mouth. Kling 3 poured and set the carafe down, and it also invented a stranger at the edge of the frame. Gemini Omni poured and set the carafe down, then failed for a smug grin and a raised fist.

Several actions, in order: Seedance 2.5

Nia gets three instructions in one prompt: take one sip, set the mug on the shelf, then turn and wave with both hands. All four models did the three steps in the right order. What separated them was the room. Seedance 2.5 kept the mug on the shelf and made the clearest wave. Kling 4 was clean, except that a yellow patch appeared in the painting behind her. Seedance 2 did the steps with a small wave. Kling 3 did the steps and broke the room, which the next section shows. Gemini Omni, run later, did the steps too, and it was the only model that kept the shelf the size the still shows.

Swap a person into a video you have: Genjutsu

A swap starts from a video, not a photo. We took Kling 3's English talking clip and swapped Camila for Layla, another AI person from the premade cast, with Genjutsu Light from Higgsfield. The café, the cup, the camera, and the timing stayed. The voice stayed too: a swap keeps the sound of the source, so Layla speaks with Camila's voice. Genjutsu Light cost 170 credits for 5 seconds, and the full Genjutsu is 579. For both side by side, see the best AI model to swap a person in a video.

Other tools do this job too. Alibaba's Wan Animate has a replacement mode and open weights. Runway's Aleph 2.0 edits footage you already have, up to 30 seconds. Kling's Motion Control moves a character from a photo with the motion of a video.

Many cheap clips: Seedance 2 Mini

When you need many clips to find one that works, the price per second counts more than the last bit of polish. Seedance 2 Mini is the cheapest video model in Hook Studio: 68 credits for 5 seconds at 720p, 34 at 480p. Seedance 2 Fast is 105 at 720p. At 720p, Gemini Omni costs less than Mini: 60 credits. A draft of a Kling 3 clip runs on Seedance 2 Mini at 480p, which is a different model, so the motion of the final will not match the draft. Mini was not part of this test.

In our test, the model whose faces looked most real was the one that broke the scene when the shot asked for more. Of the first four models, Kling 3 made the only talking takes that passed. Given three actions, it did every step, then grew the shelf and lost the mug she had just set down. Seedance 2.5 was the reverse: the cleanest three-step shot and a clean pour, and an over-acted face when it had to talk.

That is one take each, so treat it as a pattern to test, not a law. What it tells you is how to choose:

• Pick by the hard part of the shot. If the shot lives on a face saying a line, start with the model that keeps faces calm. If it lives on actions and objects, start with the one that keeps the room together.
• Split a shot that asks for both. A talking line and a three-step action can be two shots, each on its own model.
• Write the prompt for the model's weak side. For a talking clip, ask for calm and watch the take muted. For an action clip, name every object that must stay where it is.

The three names people compare come from three of the biggest video companies in the world:

• Kling is from Kuaishou, the Chinese short-video company behind Kwai. Kwai has about 60 million monthly users in Brazil, according to Caixin.
• Seedance is from ByteDance, the company behind TikTok and CapCut. ByteDance put Seedance 2.0 into CapCut, with Brazil and Mexico among the first countries.
• Veo and Gemini Omni are from Google DeepMind, at the company that owns YouTube. Google retired the Veo 3.1 models from its Gemini API on October 22, 2026, and points developers to Gemini Omni 1.2 Flash. Veo 3.1 is still on Google Cloud. Hook Studio runs Gemini Omni 1.2 Flash since November 14, 2026. Veo 3.1 cannot start from a still through our video provider, so Hook Studio does not offer it.

Why each maker's home turf matters is in who makes Kling, Seedance, and Veo.

What the leaderboards say

Artificial Analysis ranks video models by blind votes on short clips. When we read its boards on November 14, 2026, Seedance 2.5 was first for image to video and Wan 3.0 was first for text to video. Kling 3.0 was 22nd and 23rd. That rank measures which clip strangers prefer side by side. It does not measure whether a model follows your prompt, keeps your person the same, or what it costs. In our talking test, Kling 3 beat both Seedance 2.5 and Kling 4. Use the board to choose which models to test, not which one to use.

Other models worth knowing

• Wan 3.0, from Alibaba. First on the text-to-video board when we read it. Up to 30 seconds in one pass, at up to 1080p.
• Hailuo H3, from MiniMax. Up to 15 seconds at 2K, with stereo sound. MiniMax pitches it on following instructions and on drawing text and brands accurately.
• Vidu, from Shengshu. Its Q4 model has been in preview since October 7, 2026.
• Grok Imagine Video 1.5, from xAI. Out since June 2026. xAI says it brings sharper realism and better physics.
• Runway. Gen-4.5 makes new clips. Aleph 2.0 edits footage you already have, up to 30 seconds.
• Sora, from OpenAI, is gone. The app closed on April 26, 2026, and the API on September 24, 2026.
• Gemini Omni 1.2 Flash, from Google, came out on November 5, 2026, in place of Veo in the Gemini API: clips of 3 to 15 seconds, at $0.07 a second at 720p. In Hook Studio since November 14, 2026: 60 credits for 5 seconds at 720p.

Hook Studio runs Kling 3, Kling 4, four Seedance models (Seedance 2, 2.5, 2 Mini, and 2 Fast), and Gemini Omni 1.2 Flash.

The table above is where to start. Your shot is not our shot: your face, your product, your room. The way to know is to test it:

1. 1Pick the one shot your reel depends on, usually the hook.
2. 2Make one still you would post, and run it on two or three models with the same prompt.
3. 3Watch each take muted, then with sound. Note what broke: the face, the hands, the objects, the camera, or the words.
4. 4Keep the model that broke least on the part that matters, and use it for that kind of shot.
5. 5Test again when a new model comes out.
