Generate videos using OpenAI’s Sora 2 models through the Runcrate API. Sora 2 excels at realistic physics simulation, consistent object permanence, and cinematic camera work.
Sora API is being discontinued in September 2026. Plan migrations to Veo 3, Seedance, or Kling v3 before the deadline. Available models
| Model | Durations | Best for |
|---|
| Sora 2 | 4, 8, 12s | General-purpose video generation |
| Sora 2 Pro | 4, 8, 12s | Production-quality, complex scenes |
Basic text-to-video
from runcrate import Runcrate
client = Runcrate(api_key="rc_live_YOUR_API_KEY")
job = client.models.generate_video_and_save(
"sora-demo.mp4",
model="openai/sora-2",
prompt="A paper airplane folds itself from a blank sheet, launches off a wooden desk, "
"and flies through an open window into a bright blue sky. Tracking shot.",
duration=8,
on_status=lambda j: print(f" {j.status}..."),
)
Sora 2 Pro — production quality
from runcrate import Runcrate
client = Runcrate(api_key="rc_live_YOUR_API_KEY")
job = client.models.generate_video_and_save(
"hero-video.mp4",
model="openai/sora-2-pro",
prompt="Slow-motion close-up of water droplets falling onto a leaf, each creating "
"concentric ripples. Macro lens, natural diffused lighting, shallow depth of field.",
duration=12,
on_status=lambda j: print(f" {j.status}..."),
)
Sora 2 vs. alternatives
| Feature | Sora 2 | Veo 3.0 | Seedance 1.0 |
|---|
| Max duration | 12s | 8s | 12s |
| Physics realism | Excellent | Good | Good |
| Resolution | HD | 4K | HD |
| Audio | No | Yes (Veo 3 Audio) | No |
| Status | Sunsetting Sep 2026 | Active | Active |
Migration plan
The API shape is identical across all video models — changing the model parameter is the only code change needed:
| Current | Migrate to | Why |
|---|
| Sora 2 | Veo 3.0 | Higher resolution, audio support |
| Sora 2 Pro | Veo 3.0 | Comparable quality, actively maintained |
Tips
- Sora 2 excels at physical interactions — dominos, water, fabric, collisions.
- Camera language works well — “tracking shot,” “dolly zoom,” “slow motion” are understood.
- 12s is the maximum — for longer videos, generate multiple clips and stitch them.
- Start with Sora 2 for drafts, use Sora 2 Pro for finals.
