AI Video Generator
Generate AI video with Sora 2: text to video and image to video, all from one Vidney workspace.
Output
Gravity, momentum, fluid and collision are simulated rather than animated. A dive displaces water, a fall carries weight, and fast motion stays solid instead of smearing.
A diver leaps from a high board into a pool, water splashing up and rippling outward as the surface settles
Dialogue with believable lip-sync, room tone and effects are generated in the same pass, so a clip arrives speaking instead of silent.
A street saxophonist plays an upbeat melody on a busy sidewalk, with city ambience and footsteps around him
Describe subject, setting, action, lighting and camera in one paragraph and most of it survives into the render. Precise direction gets rewarded.
A red vintage convertible drives along a coastal cliff road at golden hour, side tracking shot, palm trees blurring past, the driver's scarf fluttering, warm cinematic light
Wardrobe, props, light and geography stay consistent when one prompt spans several shots. What got wet stays wet.
A woman in a yellow raincoat walks down a rainy street, then steps inside and shakes off her umbrella in a warm lamplit cafe
Water breaking over rocks, a vehicle skidding, debris scattering: the action reads as captured, not animated, because mass and collision stay consistent.
A character speaks and the audio arrives with the take: lip-synced delivery, room tone, ambience. No dubbing pass.
The quiet, believable shot: rain on a window, a hand turning a key. Small true details survive into the render.
Short vertical pieces that arrive complete with dialogue, ambience and effects, ready to post without a sound pass.

Sora 2 is OpenAI's video and audio generation model, released on September 30, 2025 through sora.com, a standalone iOS app, and later the API. OpenAI's system card describes it as a step beyond the original Sora, with more accurate physics, sharper realism, synchronized audio, enhanced steerability, and a wider stylistic range. OpenAI calls it what may be the GPT-3.5 moment for video, framing the 2024 Sora as the GPT-1 moment.
The headline improvement is physical plausibility. OpenAI's launch example is a missed basketball shot: earlier models would teleport the ball into the hoop, while Sora 2 lets it rebound off the backboard, and the company notes that the model's mistakes now tend to look like mistakes of the agent it is simulating rather than breaks in world physics. Sora 2 also generates dialogue and sound effects natively, and its cameo feature can insert a verified real person into generated scenes with their appearance and voice after a one-time consent recording.
OpenAI has not published architecture details for Sora 2, so specifics like parameter count or exact design remain undisclosed. The original Sora was described in OpenAI's 2024 technical report as a diffusion transformer operating on spacetime patches of compressed video latents. The system card states that Sora 2 was trained on diverse datasets, including publicly available internet data, third-party licensed data, and data from users and human trainers, with filtering and safety classifiers applied in the pipeline.
Every Sora asset carries C2PA provenance metadata, videos downloaded from sora.com or the app carry a visible moving watermark, and OpenAI runs internal detection tools to identify Sora-made media. At launch OpenAI deliberately limited the product: no video-to-video generation, no text-to-video of public figures, blocked generations of real people outside the consent-based cameo system, and restrictions on uploading images of photorealistic people. The company acknowledges these safeguards do not fully solve provenance and says mitigations will keep changing as risks emerge.

Sora 2 is the model people open when a shot has to obey the real world. OpenAI's model simulates gravity, momentum, buoyancy, fluid and collision closely enough that motion reads as governed by physics rather than morphed into place, so a spilled drink pools, a thrown object arcs and lands, and a body carries its own weight through a fall. Narrative directors staging dialogue beats, ad teams who need spoken lines with believable lip-sync, and creators making physics-heavy action turn to it for that plausibility, plus native audio generated in the same pass. It also follows long, dense prompts faithfully, holding many stated details at once. The fair comparison is Runway Gen-4 Turbo: pick Runway when you want a thirty-second render loop and region-level motion painting, and you can score the clip yourself afterward. Pick Sora 2 when the deliverable lives or dies on physical truth and synced sound, and you would rather write one detailed instruction than brush motion by hand. Within Vidney, Sora 2 sits a click away from those faster tiers, so you can prototype loosely and bring the keeper here to finish.

Recurring themes from public reviews, comparisons and creator write-ups. Both the good and the bad.
Creators consistently praise the jump in physical realism, pointing to natural object motion, lighting, and shadows that hold up far better than earlier video models.
Synchronized dialogue and sound effects are a frequent highlight, since reviewers found the built-in audio removes a whole separate production step, and head-to-head tests praised its dialogue and ambient sound quality.
The cameo feature is widely called the standout addition, and reviewers describe Sora 2 as the first consumer video generator that consistently rewards specific direction in prompts.
A common complaint is aggressive content moderation, with creators reporting that benign prompts frequently fail on content policy violations and that the strict filters make iteration frustrating.
Users also push back on the visible watermark on downloaded videos and note lingering failure modes, including identity drift across shots, garbled on-screen text, and fragile hand and object interactions.
