What is Sisif?
Sisif turns text prompts into short, silent portrait videos for creators, marketers and businesses. A typical clip is five seconds long and ready in two to five minutes; longer briefs can be planned as stories of up to 60 seconds. Clips cost $1 each, with monthly plans available for frequent rendering, and outputs have no watermark. The service also offers API and MCP access for automated clip ordering.
Sisif Features:
Prompt-Based Video: Describe a scene in text to generate a five-second portrait clip, usually in two to five minutes.
Story Planning: Turn a longer brief into a storyboard of planned shots for a story up to 60 seconds, with the total price shown before purchase.
Video Resolutions: Generate standard clips at 540x960 or choose the Ultra tier at 720x1280.
Clip Delivery: Receive the MP4 in your Sisif library, by email or through a webhook.
Prompt History: Each render keeps the sentence used to create it, so the same prompt can be rendered again.
API and MCP: Submit prompts through the REST API or MCP server, with webhooks and an n8n template available for workflows.
Sisif Benefits:
Faster Turnaround: Quick renders help teams prepare short video content without waiting through hours of conventional editing and production.
Lower Production Costs: Paying per clip can suit occasional video needs without the cost of hiring a production team or maintaining software subscriptions.
Clear Story Costs: Seeing a storyboard and total price before buying a longer video makes it easier to decide whether the planned result fits the budget.
Clean Deliverables: Videos arrive without a watermark, avoiding the need to remove one before using a clip.
Repeatable Results: Keeping prompts with their renders makes it easier to revisit ideas that worked for earlier posts.
Use Cases:
Short-Form Social: Create portrait clips for TikTok, Instagram Reels and YouTube Shorts when a social post needs a visual.
Product Promotion: Make product showcase or launch clips for a brand’s social channels, ads or commercials.
Educational Videos: Turn a topic into a short tutorial or explainer for YouTube or LinkedIn.
B2B Updates: Prepare brief videos for LinkedIn thought leadership or company updates.
Photo Animation: Animate an old, family or memorial photo when a still image needs movement.
