Kling vs Veo vs Seedance for product adverts: which AI video model for which shot

Every few weeks a new AI video model tops a leaderboard, and every few weeks someone asks which one to use for their adverts. The honest answer is that the question is slightly wrong. An advert is a sequence of different shots, and different models are good at different shots. The useful question is: which model for which shot?

This guide covers the models we use most for product adverts on Reigniter, what each is good at, and how we choose. It is based on how we route shots in our own product, not on a benchmark.

The short version

The rest of this article explains the reasoning, because your product may behave differently from ours.

What matters in a product advert shot

Before comparing models, it helps to be clear about what "good" means for a product advert. It is not the same as what makes a viral demo clip.

• Identity. The product must look like the product: same shape, same label, same colour, in every frame. A beautiful shot of a slightly different bottle is a failed shot.
• Brand. If a logo or wordmark is in shot, it has to survive the camera move without being redrawn.
• Motion that fits the format. A luxury hero shot wants a slow, controlled move. A UGC insert wants a little handheld wobble. The same model is rarely best at both.
• Cost per usable shot. A cheaper model that needs three attempts can cost more than a pricier one that works first time.

Kling: animating a strong still

On Reigniter you can choose Kling 3 Pro, Kling 2.6 and Kling 2.5 Turbo.

What it is good at. Taking one product photo and giving it smooth, cinematic motion. Kling animates the image you give it, which is exactly what you want when you have a good product shot and need it to move. Kling 3 Pro is our strongest single-image option, and on the Premium quality setting shots with people route to it (on Standard they route to MiniMax H3). Kling 2.5 Turbo has narrower jobs: UGC product inserts, the presenter walk-in, and shots that move from a first frame to a last frame.

Where to be careful. Because Kling animates one image rather than composing a new shot from several references, it cannot combine a product photo and a separate logo into one frame the way reference-based models can. Get the frame right first, then animate it.

Use it for: product close-ups, lifestyle moments built from a strong still, UGC-style inserts, and cutaways that need to match a Kling-rendered presenter walk-in.

Veo 3.1: when the shot needs sound

Veo 3.1 generates audio natively along with the video. That changes what a single generation can deliver: the fizz of a can opening, footsteps, room tone, a line said on camera.

What it is good at. Moments where sound and picture belong together and would be awkward to add afterwards.

Where to be careful. In a narrated advert you usually want control over the mix: a voiceover, a music bed and sound effects you choose. Reigniter adds those with ElevenLabs v3 voice (70+ languages), music and sound effects, so native audio is a tool for specific shots rather than a default.

Use it for: atmosphere, product sounds, short on-camera moments.

Seedance 2.0: choosable, but test it on your product

Seedance 2.0 is available on Reigniter and some teams like its look. We keep it in the picker because choice matters and models improve fast.

What we can report honestly is one comparison of our own. Given the same logo and the same watch shot, MiniMax H3 held the brand and produced the full parts-explosion move we asked for, where Seedance only hinted at it, and Seedance cost noticeably more for that shot. That is one test on one product, not a verdict on the model. If Seedance's style suits your brand, draw a storyboard frame and a short clip with both and compare.

MiniMax H3: the one we default to for product shots

The model that most often answers "which model for a product advert" in our routing is not in this article's title. For hero product moves (orbits, reveals, product films and stylised worlds built around a real product) we default to MiniMax H3.

Why. A product film shows one object from several angles. The model that keeps it the same object from the first shot to the last wins, and in our testing that has been H3. It also composes the product and the brand mark in one shot, so the logo is still legible after the camera moves. MiniMax Hailuo 2.3 is also available.

Presenters are a different problem

Talking-head and presenter shots are not a choice between general video models. The mouth has to follow the voice track, so these shots use lip-sync models driven by the audio. On Reigniter, presenter scenes run on Wan 2.5 and 2.6 lip-sync, and walk-and-talk scenes combine a Kling walk-in with an OmniHuman delivery. A general model picked for a talking scene would not move the mouth to your script, so the picker does not pretend otherwise. For more on these formats, see UGC-style AI adverts.

Other models worth knowing

• Luma Ray 2 and Ray 2 Flash. Flash is quick and lower-cost, useful for drafting motion. Like every video model, it needs a paid plan; the free plan is stills only.
• Runway Gen-3 Turbo and Pixverse v4.5. Further options in the picker when you want a different motion character.
• Nano Banana 2 and Flux Pro Ultra. Image models for storyboard frames and stills; Flux Schnell for quick drafts.
• Topaz for upscaling finished video, and Whisper for captions.

The full list lives on the models page.

How to choose, in practice

1. Storyboard first. Draw a still frame for each scene and fix the frame before choosing motion. Our on-brand video ad workflow covers why.
2. Pick per scene. A hero orbit, a UGC insert and a presenter line can each use a different model.
3. Compare on your product. Render the one or two scenes that matter most with two models before committing the whole advert.
4. Watch the cost of a usable shot, not the price per second. Reigniter shows each scene's credit cost before it runs, and failed scenes are refunded.

Model choice is one part of making a good advert; the brand, the product photo and the plan matter more. To see the models in context, visit the AI video page or check what each plan includes on pricing.
