description: 'A video frame or set of frames analyzed during video processing.
|
|
|
|
**PURPOSE**:
|
|
|
|
Represents frames from a video that have been analyzed by computer vision
|
|
|
|
or multimodal AI models. Used to track frame-based analysis parameters
|
|
|
|
such as sample rate (frames per second analyzed) and total frames processed.
|
|
|
|
**USE CASES**:
|
|
|
|
- Video annotation (object detection, scene analysis)
|
|
|
|
- Frame sampling configuration
|
|
|
|
- Analysis throughput tracking
|
|
|
|
- Computer vision pipeline configuration
|
|
|
|
**FRAME SAMPLE RATE**:
|
|
|
|
The sample rate determines how many frames are analyzed per second of video:
|
|
|
|
| Sample Rate | Frames/sec | Use Case |
|
|
|
|
|-------------|------------|----------|
|
|
|
|
| 0.1 fps | 1 every 10s | Overview/thumbnails |
|
|
|
|
| 1.0 fps | 1 per second | Standard analysis |
|
|
|
|
| 5.0 fps | 5 per second | Detailed analysis |
|
|
|
|
| 30.0 fps | Every frame | Exhaustive analysis |
|
|
|
|
Higher sample rates capture more detail but increase compute cost.
|
|
|
|
**MIGRATION SUPPORT**:
|
|
|
|
This class supports migration from the frame_sample_rate slot per
|
|
|
|
slot_fixes.yaml. Use with has_quantity + Quantity + has_unit + Unit.

comments:
|
|
- Created from slot_fixes.yaml migration (2026-01-22)
|
|
- Use with analyze slot to track frame analysis
|
|
- Sample rate affects both coverage and compute cost
