Search inside a video by describing the scene
Type what you are looking for, such as "a red car turns left at night", and Moments returns the matching timestamps in your video. The search model runs on your device, so the video never leaves your browser.

Search in plain words and get up to five ranked moments, each with a thumbnail and timestamp you can preview.
Search while it analyzes
Moments samples about one frame per second. You can search as soon as the first frames are ready.
Narrow and refine
Limit a search to a time range, sort by relevance or time, and refine a result to the best frame in its window.
