Case Study: Building a Video Generation Tool with Sora 2 API

4 min read

Introduction

Building an AI-driven video generation tool can dramatically reduce production timelines for creative teams. This case study walks through a real implementation using the Sora 2 API and JuheAPI workflow to construct a functional AI video generator.

Understanding Sora 2 API Capabilities

Key Features

  • Natural language to richly detailed video clips
  • Synced audio generation
  • Input via text or image
  • Guest Mode for public character IDs with @id references
  • Aspect ratio control: horizontal or vertical
  • Quality tiers: Basic, HD, Pro

Access Requirements

  • Requires a $10 top-up to Tier 2 for Sora 2 series model access
  • API endpoint: v1/chat/completions, prompts in content field

Project Planning

Defining Objectives

Aim: Build a tool that allows users to generate short, high-quality video clips with minimal input.

User stories:

  • Text-to-video generation
  • Image-enhanced video generation (Pro tier)
  • Quality and aspect ratio options

Tool Architecture Overview

  • Frontend UI for user inputs
  • Backend service handling API calls
  • Storage for generated outputs
  • Cost tracking module

Setting Up Sora 2 API

Account and Tier Upgrade

  1. Create an account on Sora platform
  2. Initiate $10 top-up to get Tier 2 access
  3. Retrieve API credentials

Endpoint Overview

v1/chat/completions handles both text-to-video and image-to-video prompts.

Workflow with JuheAPI

Why JuheAPI

JuheAPI offers streamlined integration with multiple AI models, including Sora 2, making it ideal for rapid prototyping.

Integration Steps

  1. Connect backend to JuheAPI
  2. Configure model calls to Sora 2 endpoints
  3. Handle streaming outputs

Implementing Text-to-Video

Basic Request Structure

{
  "model": "sora-2",
  "stream": true,
  "messages": [
    { "role": "user", "content": "A girl walking on the street." }
  ]
}

Example Output

  • 10-second, 720p, watermark-free clip of a girl walking on an urban street

Implementing Pro Image-to-Video

Request Structure with Images

{
  "model": "sora-2",
  "stream": true,
  "messages": [
    {
      "role": "user",
      "content": [
        { "text": "A girl walking on the street.", "type": "text" },
        { "image_url": {
           "url": "https://juheapi.com/cdn/20250603/k0kVgLClcJyhH3Pybb5AInvsLptmQV.png"
         }, "type": "image_url" }
      ]
    }
  ]
}

Example Output

  • 15-second, 1080p clip combining input image and prompt for realistic motion

Customizing Video Generation

Aspect Ratio Control

Include "horizontal" or "vertical" in the prompt to enforce landscape or portrait orientation.

Quality Tiers and Pricing

  • sora-2: $0.20 per clip (10s, 720p)
  • sora-2-pro: $1 per clip (15s, 1080p)

Managing Costs

Tier Pricing

Monitor usage via backend logs and API reporting to avoid exceeding budget.

Usage Strategies

  • Default to Basic tier for non-critical clips
  • Reserve Pro tier for final production assets

Testing and Optimization

Iterative Prompt Design

Adjust prompts for detail, pacing, and audio sync to achieve desired output.

Performance Considerations

Streaming outputs allow immediate preview and reduce waiting times.

Deployment

Packaging the Tool

Bundle backend with secure API key management

Delivery to End Users

Provide frontend where users can upload images or enter prompts, select quality and aspect ratio.

Key Results

Output Samples

  • Basic tier: crisp visuals, functional for concept demos
  • Pro tier: production-ready video clips

Benchmarks

  • Average generation time: 7–12 seconds
  • 98% successful request rate during beta

Lessons Learned

  • Clear, specific prompts yield most consistent results
  • Budget-friendly approaches require tier strategy
  • JuheAPI integration simplifies multi-endpoint handling

Conclusion

By combining Sora 2 API's advanced video generation capabilities with the integration ease of JuheAPI, we built a workflow that delivers high-quality clips tailored to diverse user demands while staying efficient and cost-conscious.
