# Frame sampling

A timestamped route from a 24 fps source to sparse, scene-aware tensor batches.

## Transcript

- **00:00:00.000–00:00:06.000** A 24 fps source is a timeline, not a bag of frames.
- **00:00:06.000–00:00:12.000** Uniform timestamps make sparse sampling reproducible.
- **00:00:12.000–00:00:18.000** Scene-aware samples add evidence around visual change.
- **00:00:18.000–00:00:24.000** Every sample keeps its timestamp when frames become tensor batches.
