Choose the right frame extraction interval

A shorter interval gives more candidates but also more duplicates, memory use, and selection work. Match the interval to how quickly meaningful visual information changes.

0.5 to 1 second

Use this range for gestures, exercise form, product movement, quick demonstrations, or searching for a precise facial expression. Expect many near-duplicates.

A fixed half-second sample still does not capture every source frame. At 30 frames per second it selects only one moment from each group of roughly fifteen frames.

2 seconds

Two seconds is a practical starting point for ordinary social clips, interviews with visual changes, recipes, and short tutorials. It creates enough context to find scenes without overwhelming the gallery.

After identifying the best region, use a shorter interval or a frame-by-frame editor for the final choice.

5 to 10 seconds

Use wider intervals for lectures, meetings, travel footage, long demonstrations, or first-pass storyboards. This is an indexing step rather than a final extraction.

Scene cuts can happen between samples. If complete scene coverage matters, combine interval sampling with manual review.

Estimate output before starting

Approximate image count by dividing video duration in seconds by the interval. A 90-second clip at two seconds produces about 45 frames; at half a second it produces about 180.

FrameFlow limits output to protect browser memory and server capacity, so use the widest interval that still answers your question.
