}Get a streaming upload storyboard
Returns a signed 4x4 WebP storyboard whose 16 tiles are sampled evenly across the requested window (durationMs/16 apart; every 5 seconds for the default 80s window) from a streaming upload source owned by the caller or their workspace. startTimeMs is relative to the source. Only startTimeMs and durationMs control the storyboard; tile count, dimensions, and format are fixed. By default returns a 302 redirect — set ?response=json to get {url, columns, rows, intervalMs} JSON instead.

Query Parameters
Start time in ms on the selected target's playback timeline. Defaults to 0.
0 <= x <= 21474836471000
Storyboard window duration in ms. Defaults to 80000; the selected target's remaining duration may shorten it. Pass the target's full duration to sample it end to end.
1 <= x <= 214748364730000
Set to 'json' to receive {url, columns, rows, intervalMs} instead of the default 302 redirect.
json "json"
Response
Returned when ?response=json is set
Signed CDN URL plus the grid layout of the requested 4x4 WebP storyboard. Returned only when ?response=json is set; otherwise the endpoint redirects to the URL with a 302.
Tiles per row
-9007199254740991 <= x <= 90071992547409914
Spacing between tiles in ms. Tile i (row-major) shows the frame at startTimeMs + i * intervalMs.
