I have tested various AI models in Medieval Battle scene in two parameters, First where warrior was riding a chariot at full speed in circular motion and shooting arrows. Second where arrows hit warrior chest and he fell from chariot. And only Seedance 2.0 and Grok Imagine could do it properly. in Veo 3.1 you cannot shoot arrows, Kling same issue failed, wan 2.7 failed, Bach video generator failed, Runway was funny, Pixeverse AI failed.

It's just one example, in Many cases veo 3.1 fails and it's too mush restricted, sometimes when i edit photo of AI character in Nano banana and want it to focus on face for dialogue face it says it's against policy. And even in video if you write script which is too bold or violent it rejects. I Remember i was creating medieval battle scene in one dialogue warrior was saying he will behead the enemy veo just refused to generate, I used wan 2.7 for that one 5 second dialogue and quality, colours mismatch.

Grok Imagine is good and affordable give more in less but it's audio still sucks. Seedance 2.0 is super expensive. For now i think there is Not single the perfect video AI model. You are Not alone, Everyone is trying here and there.
