Detecting AI Generated Content

Introduction

The AI Detection feature analyzes video frames to estimate whether the video is AI-generated, returning a verdict and confidence score.

Please note

AI Detection feature is currently only available for Encoder Version 2

Start a Task with the "ai_detection" Output

AI Detection outputs can be created by adding an 'ai_detection' output format to your transcoding job. In order to do this, use the /v1/start_encode2 method to launch a transcoding job with the output parameter set to ai_detection.

Request Example

{
  "query": {
    "source": "https://nyc3.s3.qencode.com/qencode/bbb_30s.mp4",
    "format": [
      {
        "output": "ai_detection",
        "save_frames": 1
      }
    ]
  }
}

save_frames - If set to 1 - saves analyzed frames to destination folder. If set to 1 destination would be treated AS FOLDER. In status url and download_url will be returned as usual, pointing to result JSON.

On the Transcode Media page choose AI Detection as an output format.

Access AI Detection

After the job is complete, you will be provided with a JSON file with the AI Detection verdict.

Output JSON structure:

{
  "total_frames": 5,                         
  "ai_frames": 3,                            
  "video_ai_ratio": 60.0,                    
  "verdict": "AI-GENERATED",                 
  "total_input_tokens": 6800,                
  "total_output_tokens": 475,                
  "errors": 0,                               
  "frames": [                                
    {
      "frame": "frame_0001.jpg",             
      "input_tokens": 1373,                  
      "output_tokens": 95,
      "is_ai": true,                        
      "reasoning": "The image displays...",  
      "video_ai_ratio": 60.0                 
    }
  ]
}

Saving AI Detection output

You can specify the path for the output file in the destination.url parameter. It should include filename and extension.

Request Example:

{
  "query": {
    "format": [
      {
        "output": "ai_detection",
        "destination": {
          "url": "s3://us-west.s3.qencode.com/my-bucket/my-folder/ai_detection.json"
        }
      }
    ],
    "encoder_version": "2",
    "source": "https://my-bucket.media-storage.us-west.qencode.com/source_video.mp4"
  }
}

Set the path to the result file in the Output Path field. It should include filename and extension. The default value is ai_detection.json.
