⚠️ Main Issues with Third-Party Tools

Sora 2 API Watermark-Free Generation Solution

💡 Optimal Solution: Generate Watermark-Free Videos at Source

Compared to post-processing watermark removal, a better solution is directly generating native watermark-free videos using API.

🎯 Core Advantages of API Watermark-Free Solution

🎯 Solution Recommendation: For creators and enterprise users who need to batch generate watermark-free videos, we highly recommend using APIYi apiyi.com's Sora 2 API service. The service provides native watermark-free video output, supports both text-to-video and image-to-video modes, and requires no post-processing watermark removal to obtain commercial-grade high-quality video content.

Sora 2 Watermark-Free API Technical Implementation

💻 Quick Start: Text-to-Video Example

Basic usage example (generating 10-second portrait watermark-free video):

import requests
import json

# Configure API endpoint and key
api_url = "https://api.apiyi.com/v1/chat/completions"
api_key = "YOUR_API_KEY"  # Get at apiyi.com

# Build request
headers = {
    "Authorization": f"Bearer {api_key}",
    "Content-Type": "application/json"
}

payload = {
    "model": "sora_video2",  # Portrait model
    "stream": True,  # Enable streaming output to view progress
    "messages": [
        {
            "role": "user",
            "content": [
                {
                    "type": "text",
                    "text": "A cute orange cat chasing butterflies in a sunny garden, full of life"
                }
            ]
        }
    ]
}

# 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!")

🎨 Image-to-Video Example (Support Reference Image)

# Image to video configuration
payload = {
    "model": "sora_video2-landscape",  # Landscape model
    "stream": True,
    "messages": [
        {
            "role": "user",
            "content": [
                {
                    "type": "text",
                    "text": "Animate this image with gentle breeze moving leaves and sparkling sunlight"
                },
                {
                    "type": "image_url",
                    "image_url": {
                        "url": "https://example.com/your-image.jpg"  # Or use base64
                    }
                }
            ]
        }
    ]
}

🎯 Model Selection Strategy

Based on actual testing experience, Sora 2 watermark-free model selection recommendations for different scenarios:

🎯 Selection Recommendation: For daily creation needs, we recommend prioritizing sora_video2 or sora_video2-landscape models. These two models have the highest stability, fast generation speed (2-3 minutes), and affordable pricing. If you need higher resolution and 15-second duration, you can choose the sora-2-pro-all model, but note that this model takes longer to generate (about 10 minutes). All models are provided through APIYi apiyi.com platform with unified interface calling.

🚀 API Response Format

Streaming output progress example:

> ⌛️ Task is in queue, please wait patiently...
> 🏃 Progress: 36.0%
> 🏃 Progress: 58.5%
> 🏃 Progress: 89.2%
> ✅ Video generated successfully, [click here](https://sora.gptkey.asia/assets/sora/xxx.mp4) to view video

Key field descriptions:

• finish_reason: "stop" – Generation completion identifier
• Video link – Returned in markdown format, valid for 24 hours
• Generation time – Usually 2-3 minutes (10s video)

🔍 Technical Note: APIYi apiyi.com's Sora 2 API uses streaming output design to view video generation progress in real-time. All generated videos are stored on domestic Alibaba Cloud CDN for fast and stable downloads. Note that video storage is valid for 24 hours, recommend downloading immediately after generation. For long-term storage or batch video asset management, the platform provides complete media management API and technical documentation support.

Sora 2 Watermark Removal Best Practices

✅ Recommended Practice Process

📋 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.
