Run the same idea through both
Pick a prompt, make it with each model and keep the one you like. The clips were made with Cirrela to show the idea, not necessarily with these two models.
A lighthouse keeper watching a storm roll in, dark waves crashing on the rocks below, cinematic wide shot, wind and distant thunder
Luxury commercial: a sculpted glass perfume bottle slowly rotates on wet black stone, water droplets catching a thin beam of golden light, mist drifting, macro lens, no text, no logo, deep cinematic sound design
Polished 3D animation: a small friendly robot carefully assembles a glowing glass cube on a clean pastel studio set, soft global illumination, smooth camera orbit, playful mechanical sounds
Fast FPV drone skimming over a palm-lined beach at golden hour, waves rolling in, warm haze, anamorphic lens flare, ocean and wind sound
