    ]
}

# Send request
response = requests.post(api_url, headers=headers, json=payload, stream=True)

# Process streaming response
for line in response.iter_lines():
    if line:
        line_str = line.decode('utf-8')
        if line_str.startswith('data: '):
            data_str = line_str[6:]
            if data_str == '[DONE]':
                break
            try:
                data = json.loads(data_str)
                content = data['choices'][0]['delta'].get('content', '')
                if content:
                    print(content, end='')
            except:
                pass

print("\nVideo generation complete!")

Sora 2 Watermark Removal Best Practices

✅ Recommended Practice Process

Practice Point Specific Recommendation Notes
🎯 Solution Selection Prioritize API direct generation of watermark-free videos Avoid quality loss and privacy risks
⚡ Model Selection Choose portrait/landscape model based on video purpose Portrait for short videos, landscape for long videos
💡 Prompt Optimization Clearly describe scenes, avoid real people Sora 2 has strict restrictions on real person portraits
🔧 Error Handling Adjust prompts promptly when content violates rules Violation requests are charged but no video output
📦 Video Management Download and save within 24 hours after generation Video links expire after expiration

📋 Pitfall Guide

Common Error 1: Sora 2 Real Person Portrait Restriction

Problem: Video generation fails using real person photos

Reason: Sora 2 currently only supports authorized real people (like @sama), ordinary user uploaded real person photos are rejected

Solutions:

  • Use cartoon characters or anime characters instead
  • Wait for Sora Cameo function to open (requires invitation code)
  • Generate character scenes through descriptive text instead of images

Common Error 2: Content Violation Causing Charges

Problem: Prompt violates content policy, generation fails but still charged

Reason: API request succeeds (HTTP 200), but content review doesn't pass

Solutions:

  • First test prompts on sora.chatgpt.com official website
  • Avoid copyrighted characters, violent content, politically sensitive topics
  • Use generic natural scenes and abstract concepts

🚨 Important Reminder: For commercial projects, recommend using small recharge for testing validation before large-scale batch generation. APIYi apiyi.com platform provides first recharge discount, new users can get extra $1 when recharging $5 (about 35 RMB), enough to test 30+ videos. The platform also provides detailed error code documentation and technical support, problems can be quickly resolved through the help center.

Recommended batch generation solution:

  1. API calling method: Use Python/JavaScript scripts for batch calling
  2. Concurrency control: Recommend processing 3-5 video tasks simultaneously
  3. Error retry: Implement exponential backoff retry mechanism
  4. Video management: Automatically download and rename video files

Example batch processing script:

import asyncio
import aiohttp

async def generate_video(prompt, model="sora_video2"):
    # Async API call to generate video
    # Implement progress monitoring and error handling
    pass

async def batch_generate(prompts):
    tasks = [generate_video(p) for p in prompts]
    return await asyncio.gather(*tasks)

# Batch generate 100 videos
prompts = ["prompt1", "prompt2", ...]  # Read from file
results = asyncio.run(batch_generate(prompts))

Q5: Why am I still charged when generation fails sometimes?

Charging mechanism explanation:

These situations are charged:

  • Content violation (content violation): Prompt or image triggers review rules
  • Request success (HTTP 200): API returned response, even without video

These situations are not charged:

  • Service busy (heavy load): Official queue failure, automatic retry
  • Network error (timeout): Request didn't reach server
  • Authentication failure (401): API Key error or insufficient balance

Pitfall avoidance strategy:

  1. First test prompts on official sora.chatgpt.com to see if they pass review
  2. Avoid uploading real face photos as reference images
  3. Don't use copyrighted character names (like Disney characters)
  4. Use small recharge for testing when first using, validate prompt templates

💡 Cost control recommendation: APIYi apiyi.com platform provides detailed consumption records and failure reason analysis, helping users optimize prompts and reduce invalid request rates.
