New body-physics test for the best AI video tools:
The newly released Grok Imagine 1.5, the king Seedance 2.0, Google’s “revolutionary super-duper” Gemini Omni Flash, and the old-timer Kling 3.0 Pro.
This time I tested how each model handles realistic running motion, body movement, fabric physics, and natural secondary motion.
And the result was much less obvious than I expected.
Believe it or not, I can’t call Seedance the clear winner this time.
Each model got several attempts.
- Grok Imagine 1.5:
The new version is finally available on the official Grok website, so I could properly test it.
Honestly, I didn’t notice a massive improvement over the previous version. Still, the result was acceptable.
It produced the most cartoonish image, and the woman runs as if she’s wearing heels, but the body physics were decent enough. It also understood the instructions quickly and followed them correctly.
- Kling 3.0 Pro:
The old man decided to test my patience.
It repeatedly blocked a simple running scene as adult content, then misunderstood the instructions several times.
The successful result has the most realistic lighting and frame rate, but the actual body physics look strange. It almost feels like loose foam padding is bouncing inside the leggings.
There are also several visible artifacts and unnatural movements.
- Gemini Omni Flash:
As usual, it gave me that strange slow-motion, low-FPS look that Google models seem to love.
But it didn’t censor anything, understood the instructions immediately, and produced a beautiful, realistic result.
Surprisingly, this is the output I liked the most in this test.
- Seedance 2.0:
Seedance also blocked a couple of generations, just like Kling, but eventually produced a strong result.
It delivered the most beautiful and visually appealing footage, but I honestly expected better physics.
The video looks great, yet I can’t confidently call it the most physically accurate result.
- My ranking:
1. Gemini Omni Flash — not perfect, but the best overall result for me
2. Seedance 2.0 — visually stunning, but I preferred Omni’s physics
3. Grok Imagine 1.5 — cartoonish look and strange running, but still acceptable
4. Kling 3.0 Pro — the longest wait, the strangest physics, and the most inconsistent result
Do you agree with my ranking?

New action test: Seedance 2.0 vs Gemini Omni Flash vs Kling 3.0 Pro vs Google Veo 3.1.
This time, a Lara Croft-style heroine had to escape armed enemies, perform multiple stunts, and shoot back during one complex action sequence.
Each model got 4–6 attempts.
I brought Veo 3.1 back instead of Grok Imagine. The reason is simple: Veo handled this scene better, while new Grok 1.5 still isn’t available on the official Grok website, so I left it out.
- Google Veo 3.1:
Predictably finished last, but I wouldn’t call the result terrible.
It clearly looks weaker and more outdated than the others, but for such a difficult scene, the result was still acceptable.
- Gemini Omni Flash:
Not perfect, but still pretty good.
The stunts, physics, and overall execution worked well. My main issue is Google’s familiar low-FPS look. The footage constantly feels slightly slowed down, which makes it less cinematic than both Seedance and Kling.
Still, I liked the result, and it was strong enough to take second place.
- Kling 3.0 Pro:
Better than I expected.
Its biggest problem is character consistency. The heroine and other characters become distorted during fast movement, with plenty of unnatural poses and animation errors when you look closely.
The overall result is still acceptable. Worse than Gemini Omni Flash, but definitely better than Veo 3.1.
- Seedance 2.0
This was Seedance’s territory.
Complex action remains its greatest strength, and it started producing excellent results within the first few attempts.
The physics, movement, instruction following, and overall intensity were all impressive. This might be one of the best results I’ve ever received from Seedance.
This test once again shows that Seedance remains the king of difficult action scenes.
- My ranking:
1. Seedance 2.0 — clearly on another level
2. Gemini Omni Flash — strong, but held back by the slow-motion feel
3. Kling 3.0 Pro — better than expected
4. Google Veo 3.1 — predictably failed again
What do you think of the new test?

@c00kingwithai Exactly. The frustrating part is that the model willing to accept the prompt often isn’t the one that handles the motion best. So sadly, there doesn’t seem to be a secret fix we’re both missing 😅

@c00kingwithai Thank you! The moderation feels completely inconsistent. Rewording the action or changing the camera angle sometimes helps, but I still haven’t found a reliable workaround either
Another body-physics test for the best AI video models.
This time, Elon’s pride and joy Grok Imagine 1.5 faces the old but stubborn Kling 3.0 Pro, China’s flagship Seedance 2.0, and America’s shiny newcomer Gemini Omni Flash, which developers called “revolutionary,” although I’m still waiting to see the revolution.
The new battlefield: jump-rope exercises filmed from the front.
There is a lot to analyze here. But let’s be honest. We all know exactly where everyone will be looking. Or rather, at which two points.
The result was surprisingly close.
- Kling 3.0 Pro:
In this test, Kling was the only model that detected adult content in a completely harmless fitness scene and repeatedly refused to generate it.
Which is especially funny considering how often Kling is used to bypass censorship with celebrity faces, yet apparently a woman jumping rope is where it draws the moral line.
After several attempts, it finally produced a usable result.
The lighting and overall realism are strong, as usual, but the actual body physics are the weakest here. It also missed the visual instructions from the prompt, giving me an older-looking model with less flattering proportions instead of the athletic, curvy character I requested.
Not terrible, but definitely not Kling’s finest performance.
- Grok Imagine 1.5:
Apparently, Elon’s creation performs better from the front than from behind.
Grok understood the task immediately, generated quickly, and didn’t complain about censorship.
The image still has that unmistakably cartoonish Grok look, but the jumping motion is surprisingly fun and the body physics are actually decent.
It feels more like a cutscene from a video game than real footage, but this is still one of Grok’s better results in my recent tests.
- Gemini Omni Flash:
Once again, Omni produced a beautiful and polished image.
Google’s usual slow-motion, low-FPS effect is normally one of its biggest weaknesses, but in this specific test it actually worked in its favor.
The slower movement makes the secondary motion much easier to see, and the body physics look smooth, convincing, and surprisingly natural.
I liked this result a lot.
- Seedance 2.0:
Seedance performed much better than in the previous body-physics test.
The footage is dynamic, vibrant, realistic, and visually the strongest of the four.
The physics still don’t look completely natural to me, but the overall result is so convincing that it deserves first place, or at least a shared victory with Omni Flash.
Omni may have slightly better body physics, while Seedance wins in movement, realism, energy, and overall image quality.
- My ranking:
1. Seedance 2.0 and Gemini Omni Flash. A shared first place. Omni wins on body physics, while Seedance wins on overall realism, visual quality, and dynamic motion. If I absolutely had to choose one, Seedance would take it by a very small margin.
2. Grok Imagine 1.5. Still behind the two flagships, but noticeably better than in the previous tests.
3. Kling 3.0 Pro. Too much censorship, weaker instruction following, and the least convincing physics. The realistic lighting and natural-looking footage save it from being a complete failure.
What’s your ranking?
And if anyone wants the prompt, ask in the comments and I’ll share it.

@arnawa_widagda That’s a sharp read. Omni was the only one that stayed convincing from start to finish for me. Grok looked rougher, but its motion held together surprisingly well
@icreateddisco4u but I ranked Kling last because the body physics looked off to me, although its restrained camera work did help it feel more grounded.
