Create video

Overview

Although this interface shares the "videos" endpoint, there are two distinct formats for better differentiation:

Official Format - Compatible with OpenAI's official API format

CometAPI Self-Developed - CometAPI's enhanced format with unique features

Supported Models

Currently supported model IDs:

sora-2-all - Supports video durations: 10 or 15 seconds (maximum 15 seconds)

sora-2-pro-all - Supports video durations: 10, 15, or 25 seconds (maximum 25 seconds)

Key Differences: Self-Developed vs Official Format

The CometAPI Self-Developed interface has the following main differences compared to the Official Format:

Duration Limitations: Models with the -all suffix only support specific duration values for the seconds parameter:

sora-2-all: 10 or 15 seconds only (does not support 25 seconds)

sora-2-pro-all: 10, 15, or 25 seconds

Pricing Structure: Pricing differs from the Official Format models

Important Notes

⚠️ Asynchronous Processing
Video generation requires considerable time and uses asynchronous mode. After creating a task, a task ID is returned immediately. You need to use the query interface to get generation progress and results.

⚠️ Content Policy
Generated video content must comply with OpenAI's usage policies. Content that is illegal, violent, pornographic, or infringes on copyrights is prohibited.

📋 Storyboard Mode
The API supports Storyboard functionality for creating sequential multi-shot videos. When using storyboard mode, the prompt must strictly follow this format:

Shot 1:\nduration: 7.5sec\nScene: The plane takes off.\n\nShot 2:\nduration: 7.5sec\nScene: The plane lands.
