What one clip includes

Recent renders, with the prompt that made each one 5 s · 540x960 portrait
01Golden hour on a tropical beach, a confident young woman in a red bikini walks out of the turquoise surf toward the camera, wet hair, sun flare, slow motion, cinematic 35mm film look
02Backyard security camera footage at dusk, the lid of a metal trash can lifts and a raccoon pops out holding a cracker, chewing and staring straight into the camera
03Hand-drawn anime film style, a girl on a bicycle rides down a hill toward a seaside town in summer, wind in her hair, huge fluffy clouds, vibrant watercolor colors
04Children's picture book animation, soft watercolor and pencil textures, a little bear in a red scarf sits on a mossy log holding a glowing lantern as fireflies drift down and gather around him in a moonlit forest, gentle and cozy
053D animated movie style, a tiny fluffy orange kitten in an astronaut suit floats inside a spaceship, chasing a floating bubble of milk, big glossy eyes, soft warm lighting
06Claymation stop-motion, a grumpy clay chef tosses a giant pancake that flips in the air and lands on his head, cozy miniature kitchen, visible fingerprint texture

Most clips take 2-5 minutes. You get the MP4 in your library, by email or by webhook. The ultra tier is 720x1280.

API and MCP server

POST a prompt, poll for the file. The price and terms are the same as on this page. Add the MCP server to an MCP client and an agent can order a clip and pay for it in the same call, over Stripe's machine payments protocol (MPP). There is no key to set up and nothing recurring. Webhooks and an n8n template are there if you need them.

Questions

Can I try Sisif before paying?

There is no trial. A new account has 0 credits, so the first render is a purchase. You can plan 3 storyboards in 24 hours before you pay for anything, and 10 after your first purchase.

Can I get a clip without a watermark if I don't pay?

No. Every clip is a purchase, and no clip carries a watermark.

Can I see the clip before I pay?

For a longer brief, yes. You see a storyboard of the planned shots and the price first. A single clip is not previewed as video before you buy it. The example clips on this page show what the model does, each with its prompt.

How much is a story?

A story is a brief planned into shots, up to 60 seconds. It costs $1 per 5 s of the length you choose. You see the storyboard and the total before you pay.

Is tax included?

Prices are before tax. VAT, GST or sales tax is added at checkout from your billing address.

Which model renders the clips?

An open-weights video model on RunPod GPUs. Clips are not sent to a third-party video API.
