GENERATE
— renders with sora 2 — 45 crPROMPT SAMPLES
— written for this engine — use one as a starting pointPROMPT_01
A crowded farmers market: a dropped orange rolls downhill between shoppers' feet, a kid chases it, vendors laugh — sound follows the chase.
PROMPT_02
Twelve seconds: a glassblower shapes a glowing vessel, turns it, taps it free, and holds it up to the light — workshop sounds throughout.
PROMPT_03
A wave crashes through a living room in slow motion, furniture lifting and drifting, sunlight refracting through the water.
PROMPT_04
Rooftop chess game in the wind: a gust knocks pieces over one by one, both players scramble to catch them, city humming below.
PROMPT_05
A marble run spans a cluttered workshop: the marble drops, triggers a mousetrap, tips a ruler, rings a bell — each sound on its beat.
PROMPT_06
Dog park chain reaction: one dog steals a frisbee, three others give chase, owners spin in their wake — barks and laughter tracking the chaos.
ABOUT
Sora 2 is OpenAI's video model, and its strength is scene understanding: multiple subjects interacting, cause and effect, objects that persist and collide believably. Where simpler engines render a moving picture, Sora renders a small simulated world — with audio synced to what happens in it.
That world-model quality shows up in the details: a dropped object rolls where the floor says it should, a crowd parts around the person moving through it, and the second half of a shot depends on the first actually having happened. Prompts with real causality — chains, chases, collisions — are where Sora out-renders everything else.
Shots come in 4, 8, or 12 seconds, portrait or landscape. It is the one deliberately slow engine in the studio — renders take noticeably longer — so it rewards prompts that use that patience: busy compositions, interactions, and moments where things have to happen in the right order. For a single clean subject in motion, Veo 3.1 gets there faster.
STRENGTHS
— what this engine does better than the others- Multi-subject scenes: several actors moving independently in one coherent space
- True cause and effect — the shot's second half depends on its first
- Objects persist, collide and occlude believably instead of morphing away
- Audio synced to events: the splash lands when the water does
- Surreal premises rendered with real-world physics for maximum contrast
PROMPTING TIPS
— how to talk to this model- TIP_01Write causality into the prompt — "a gust knocks pieces over one by one" — Sora renders sequences, not just states.
- TIP_02Use the 12-second option for chains of events; shorter cuts amputate the payoff.
- TIP_03Give each subject in a multi-actor scene its own verb so nobody stands around waiting.
- TIP_04Expect the render to take longer than other engines — queue it and keep working; it lands in History.
USE CASES
01
Multi-subject scenes
Crowds, teams, a table of people — shots where several actors have to move independently and still share one coherent space.
02
Cause-and-effect beats
A domino run, a spill, a catch: sequences where the second half of the shot depends on the first actually happening.
03
Synced sound moments
The splash lands when the water does. Impacts, footsteps, and voices arrive on the frame they belong to.
04
Surreal-but-grounded ideas
Impossible premises rendered with real-world physics — the contrast is what makes the shot.
