video_id as a scope. Text searches run within a collection, while image searches can also run across your account. See Search a collection.
After you obtain a video_id from a search result or collection listing, fetch that video directly:
playback_url is a presigned URL valid for about an hour: fetch a fresh one each time you need to play the video rather than caching it. See Metadata for every field on the video object.
If you want “more like this, in this video”
If a search already returned segments from the video you care about, use each segment’svideo_id to filter the response client-side instead of making another request. To find visually similar moments across the same collection, submit one of the video’s frame thumbnails as a reference image. See Image search.
