AI Video Model Comparison - 10 Models Tested

Project Dream lets you explore, test, and push the limits of AI video models, all in one place. It also streamlines side-by-side model comparison for faster evaluation.

If you've ever tried AI video generation, you've probably noticed that no single model does it all. Each has its own strengths and quirks. Some excel at cinematic motion, others at precise VFX or static control.

To help you navigate through the options, we ran a side-by-side model comparison of today's most popular AI video models and tested how they perform across different scenarios.

Our goal wasn't to find a single winner, but to create a practical guide, a quick way to see which model fits your creative needs, workflow, and budget, including archviz projects.

Overview

Every model was tested under the same conditions:

• Identical prompts, images, and lighting

• Five categories – fire, water, fireworks, crowds and character walking

• Three variations per test

We compared ten models available in Project Dream:

Runway Gen 4, Kling 2.1 / 2.5 Turbo, Wan 2.2, Minimax Hailuo Pro, Veo 3 / Veo 3 Fast, Seedance 1.0 Pro, Vidu Q1, and Luma Ray 2 / Flash and rated each result by movement, realism, quality, and stability

This setup allowed us to isolate each model’s behaviour, showing clear patterns of where they shine and where they struggle across AI video use cases.

Fire

Fire was one of the best categories for spotting differences between models. It’s a tricky effect because good fire needs movement, glow, smoke, and realism at different scales (from large blazes to small candle flames).

Best Performers

• Veo 3 / Veo 3 Fast – Most realistic fire overall. Natural movement, smoke, and glow, with only minimal camera drift.

• Kling 2.1 – Excellent flame behavior and static control. Handles both large and small fires well; best with short, simple prompts.

Solid Alternatives

• Runway Gen 4 – Good large-scale fire and cinematic motion, but tends to add slight camera movement.

• Kling 2.5 Turbo – Decent but flatter motion than 2.1; use when you need quicker renders.

Not Recommended

• Wan 2.2 / Minimax / Vidu Q1 / Luma Ray 2 / Seedance – Inconsistent or unrealistic across all tests. Most added unwanted motion or failed to simulate believable flames.

Recommendation:
Start with Veo 3 or Kling 2.1 for realistic fire. Use Runway Gen 4 if you want a more cinematic, moving-camera feel.

Water

Water is one of the hardest effects for AI to get right realistic results depend on natural flow, foam, splashes, and wet surface interaction.

Best Performers

• Veo 3 / Veo 3 Fast – Most consistent and realistic across all tests. Natural wave motion, believable foam and splashes, and solid handling of wet sand. Occasional slight camera drift.

• Kling 2.1 – Excellent wave realism and movement. Produces high-quality water with clean flow; works best with short prompts. Slower to render but worth it for precision.

Solid Alternatives

• Runway Gen 4 – Convincing motion and foam, but struggles with wet sand, which can appear to “move” unnaturally.

• Kling 2.5 Turbo – Great for wide ocean shots and faster output, but lacks small-detail realism like splashes or raindrops.

Not Recommended

• Wan 2.2 / Minimax / Seedance / Vidu Q1 / Luma Ray 2 – Too unstable or unrealistic. Common issues included over-fast flow, unwanted camera motion, or parallax artifacts.

Recommendation:
For realistic and detailed water scenes, use Veo 3 or Kling 2.1. For cinematic, faster renders, Runway Gen 4 or Kling 2.5 Turbo are solid alternatives.

Fireworks

Fireworks were one of the most challenging tests. Realistic results depend on bright lighting, natural smoke trails, and smooth timing. This category clearly separated cinematic models from true VFX performers.

Best Performers

• Veo 3 / Veo 3 Fast – Outstanding realism. Natural light and smoke, accurate timing, and static shots with minimal artifacts. The most convincing fireworks overall.

• Kling 2.1 – Excellent smoke and brightness control; realistic movement and detail. Works best with short, simple prompts.

Solid Alternatives

• Seedance – Surprisingly strong. Good smoke and timing, though sometimes slightly over-lit.

• Kling 2.5 Turbo – Similar to Kling 2.1 but with a bit more exaggeration; great when speed matters.

• Runway Gen 4 – Dramatic look with solid effects, but tends to add unwanted camera motion.

Not Recommended

• Wan 2.2 / Minimax / Vidu Q1 / Luma Ray 2 – Too unstable or cinematic for static fireworks scenes. Frequent artifacts, slow motion, or handheld-style movement.

Recommendation:
For realistic fireworks, start with Veo 3 or Kling 2.1. Use Seedance or Kling 2.5 Turbo if you want faster or slightly more stylized results.

Crowd Stadium

Crowd scenes were among the toughest tests. Unlike fire or water, a stadium shot depends on hundreds of small, coordinated movements, hands waving, flags swinging, people reacting at different speeds. Small animation errors stand out instantly.

Best Performers

• Veo 3 / Veo 3 Fast – Most convincing crowd behavior overall. Hand and flag movement felt natural, and it handled scale well with only minor artifacts.

• Seedance – A surprise success. Managed realistic cheering and large-scale motion; sometimes added slight camera drift but easily fixed with prompt tuning.

Solid Alternatives

• Kling 2.5 Turbo – Acceptable animation in smaller crowds, though artifacts appear in dense scenes.

• Kling 2.1 – Kept the camera static but struggled with clean motion; usable for simpler crowd setups.

Not Recommended

• Runway Gen 4 / Wan 2.2 / Minimax / Vidu Q1 / Luma Ray 2 – Too static, noisy, or cinematic. Often added unwanted motion or distorted figures.

Recommendation:
Use Veo 3 or Seedance for natural, dynamic crowd scenes. If you need faster output, Kling 2.5 Turbo is a workable fallback.

Walking Characters

Walking characters bring life to any archviz scene, but they’re one of the hardest effects for AI to handle. Realistic results require coordinated body motion, natural expressions, and consistent framing, areas where many models struggle.

Best Performers

• Veo 3 / Veo 3 Fast – Most realistic overall. Smooth walking motion, natural face expressions, and solid interactions. Occasionally introduces camera tracking, so emphasize “static camera” in prompts.

• Kling 2.5 Turbo / Kling 2.1 – Convincing character motion with some creative additions. 2.5 handles movement and focus better, while 2.1 is steadier but slower.

Solid Alternatives

• Seedance – Natural body movement and expressions, though it sometimes duplicates characters.

• Runway Gen 4 – Decent motion but inconsistent speed and background artifacts.

Not Recommended

• Wan 2.2 / Minimax / Vidu Q1 / Luma Ray 2 – Unstable or unrealistic motion. Vidu Q1 was too slow, Luma Ray 2 too cinematic, and others suffered from jitter or distortions.

Recommendation:
For realistic walking and crowd interaction, choose Veo 3 or Kling 2.5 Turbo. Use Seedance or Runway Gen 4 if you need quick, simpler background motion.

Conclusion

Testing these models side by side made one thing clear: each has its own creative personality. Some focus on realism and control (Veo 3, Kling 2.1), others prioritize speed (Kling 2.5 Turbo, Seedance), while a few lean into cinematic style (Luma Ray 2, Vidu Q1).

There's no single "best" model, only the right one for the job. Your choice depends on what matters most: realism, speed, or style, whether for VFX, general content, or archviz workflows.

AI video generation is evolving fast and we'll keep expanding Project Dream as new models roll out. This model comparison will be updated as the tools improve.
