Hosted file: 1280×704 pixels.

Prompt: Convenience store entrance after light rain; wet pavement reflections; a night clerk in a blue vest hands a cup of hot cocoa to a lone traveler; both glance up as a meteor streaks across the sky; warm interior light vs cool street; soft steam from the cup; quiet city ambience

Sora 2 prompts

Use these as directing notes. Where a prompt mentions a length or frame that this model does not offer, map it to 4, 8, or 12 seconds and 720×1280 or 1280×720 before you generate.

Convenience store night

Prompt

Convenience store entrance after rain; street reflections; meteors streak above. Characters: Night clerk (blue vest) + lone traveler. Action: Clerk hands over hot cocoa; both glance up to watch a meteor; traveler bows in thanks. Camera: Warm interior push-out → meteor reflected in puddle → shoulders-together upshot → rack focus back to cup steam. Look & Lighting: Anime-real blend; clean mirror-wet pavement with cool/warm contrast. Physics & Motion: Stable handoff; believable steam and drips. Audio: Distant city ambience + light electronic pad; soft “Thanks—the road feels closer now.”

Einstein and Tesla in the ring

Prompt

Albert Einstein and Nikola Tesla having a UFC fight

Claymation kitchen

Prompt

Whimsical claymation kitchen. A round-faced clay chef kneads pastel-colored dough that springs to life as tiny dancing croissants. Fingerprints visible in clay, hand-painted textures, light flicker like real stop-motion. Chef flips a pan; pastries form a smiling face on the plate. Cozy, warm practical lighting. Params: 4:5 or 1:1, 8–10s, 12–15 fps (intentional stutter), static camera + 1 subtle dolly, acoustic pizzicato score

Underwater macro reef

Prompt

Underwater macro world at dawn. A cathedral of branching coral sways; translucent shrimp clean a parrotfish that drifts past. Particulate backscatter in god-rays, micro-bubbles rising, refraction and chromatic aberration on the lens port. Soft, ethereal palette; no humans, no gear visible. Params: 16:9, 10–12s, 30 fps, locked macro with shallow DOF, natural ambisonic reef SFX, gentle exposure rolls.

Santorini day to night

Prompt

Single locked shot overlooking whitewashed Santorini rooftops and blue domes. Day-to-night time-lapse: clouds streak, sunset blooms orange-pink, windows light up, Milky Way arcs into view. Subtle people ghosting, twinkle in distant boats. Filmic grain. Params: 16:9, 8–12s, simulated timelapse cadence, ambient wind + distant chatter morphing to quiet night.

Coffee grinder commercial

Prompt

Premium matte-black coffee grinder on a rotating turntable. Hard key light with rim highlights; slow hero spin. Coffee beans explode into a suspended particle galaxy that re-forms into the brand mark (generic). Crisp typography space on right side. Ultra-clean, dust motes, perfect reflections. Params: 1:1 or 16:9, 6–8s, 60 fps (but play back at 30 for smoothness), seamless loop, minimal percussive ticks.

What is the Sora 2 AI video generator?

What is Sora 2?

Sora 2, sometimes called Sora 2.0, is OpenAI’s video-and-audio model announced on September 30, 2025. OpenAI’s announcement describes it as more physically accurate and more controllable than earlier Sora systems, with synchronized dialogue and sound effects, and still imperfect.

Sora AI video generator on RenderFlow

On RenderFlow AI, this page is the standard text-to-video generator: 720×1280 or 1280×720, 4, 8, or 12 seconds, 10 credits per second of video. It is billed in RenderFlow credits. It does not grant access to OpenAI’s consumer Sora app. OpenAI’s announcement page states that the Sora product was discontinued on April 26, 2026. OpenAI’s video-generation guide says the Sora 2 models and Videos API shut down on September 24, 2026. RenderFlow’s catalog still offers this endpoint as openai/sora-2-text-to-video through wavespeed. Treat that as current platform access, not a promise that OpenAI’s own app or API is open.

How to use the Sora 2 AI video generator

A usable pass is a beat sheet, one camera idea, and an explicit sound note — then a short render before you spend credits on a longer one.

Sora 2 AI video generation

  1. 1. Write the beats before the adjectives

    Decide who is in the scene, what changes, and how it ends. Sora 2 follows multi-beat instructions more reliably when the prompt is a short sequence — opening, turn, ending — instead of a static mood board.

  2. 2. Set size and duration for the placement

    Choose 720×1280 or 1280×720. Portrait (720×1280) fits vertical feeds. Landscape (1280×720) fits widescreen. Then pick 4, 8, or 12 seconds. 10 credits per second of video. A short proof of the key beat is the cheaper first render.

  3. 3. Name the camera in order

    Add the shot as timed direction: push-in, locked wide, rack focus, or a single dolly. One camera idea per clip is easier to judge than a prompt that asks for several setups at once.

  4. 4. Direct the sound in the same prompt

    There is no separate audio switch on this model. Name the ambience and put any spoken line in quotes. The convenience-store example asks for quiet city ambience, steam, and a meteor — sound and picture are one prompt.

Sora 2 AI video generator sound and physics

Sora 2 sound and dialogue

OpenAI presented Sora 2 as a video-and-audio model: ambience, effects, and speech in the same render as the picture. On this page you steer that mix in prose. Name the room tone, and put spoken lines in quotes so it is obvious which words should be said. Undirected prompts can still produce sound, so silence is a direction you should write if you want it.

Physics and motion

OpenAI’s announcement says Sora 2 is better at keeping objects on physically plausible paths than earlier Sora systems, and that it still makes mistakes. Ask for one clear action — a handoff, a pour, a glance — and check contact, steam, and reflections on the review. Readable on-screen text and large crowds are poor bets inside the clip; add type in an editor and keep the cast small.

Sora 2 image to video generator

Image-to-video is not a mode on this page. Use the Sora 2 image to video model when the clip should start from a still: image, prompt, and a duration of 4, 8, or 12 seconds, at 10 credits per second, with no frame-size control.

Sora 2 AI image to video

Sora 2 Image to Video Pro is the higher tier of that still-to-video workflow: 720p at 30 credits per second or 1080p at 50, for the same 4, 8, or 12 second durations. For a different text-to-video model, compare Google Veo 3 (200 credits per video). For image-to-video at a lower credit rate, see MiniMax H3 Image to Video (4 credits per second at 480p, or 8 at 768p).

Sora 2 AI video generator FAQ

Pricing Terms of service

Do I need an OpenAI account to use Sora 2 on RenderFlow?

No. This page runs Sora 2 text-to-video with a RenderFlow account and credits. It is not a login to OpenAI’s consumer Sora app. OpenAI says that Sora product was discontinued on April 26, 2026, and OpenAI’s developer docs say the Sora 2 models and Videos API shut down on September 24, 2026. RenderFlow’s catalog still lists this endpoint as openai/sora-2-text-to-video (provider: wavespeed). That platform availability is separate from OpenAI’s app and can change.

Does Sora 2 include sound?

OpenAI’s Sora 2 announcement describes synchronized dialogue and sound effects generated with the picture. On RenderFlow the request form has size, prompt, and duration only — there is no audio on/off control — so put ambience and quoted dialogue in the prompt.
