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.
1Start 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"
}
]
}
}On the Transcode Media page choose AI Detection as an output format.

2Access 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
}
]
}| total_frames | number of frames processed |
| ai_frames | frames classified as AI |
| video_ai_ratio | AI percentage (0-100) |
| verdict | "AI-GENERATED" or "REAL" |
| total_input_tokens | sum of input tokens across all frames |
| total_output_tokens | sum of output tokens across all frames |
| errors | number of failed API calls |
| frame | filename |
| input_tokens | tokens consumed for this frame |
| output_tokens | tokens consumed for this frame |
| is_ai | true/false/null (null on error) |
| reasoning | model's analysis text (VERDICT line stripped) |
| video_ai_ratio | same as top-level, copied to each frame |
3Saving 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.
