inspect color
Measure a still as scopes: black and white points, crushed and blown fractions, mean brightness, luma and hue histograms, zone balance, saturation and color bias (warm_cool positive warm, green_magenta positive green). Takes an image item, one moment of a video item, up to 12 items, or one composited frame of a timeline (a canvas slide: render_canvas it, then measure the image). correction suggests a grade only where the exposure or a cast on neutral areas is plainly at fault, with what it saw; with reference, the gap comes back as hints on the same fields. points, lines and key_color measure at full size and replace the scopes: the color at a point, and where a row or column leaves the picture’s ground, in pixels and as fractions, the units of a crop. Free, except drawing a timeline frame: cloud processing.
Authorizations
An API key (es_live_…) from Settings, under API keys, or an OAuth access token.
Headers
Retry a paid dispatch safely: the same key returns the job already dispatched instead of charging again.
The workspace this one call acts in, when it is not the default: for a key or a connected agent, one of the workspaces the user allowed it.
Body
The item to measure: an image, or a video with at_seconds. One of ref, refs or timeline_id.
Up to 12 items measured the same way; one that cannot be read comes back as {ref, error}.
1 - 12 elementsAn item ref, item id, or the job id that made it.
Measure a composited frame of this timeline instead of an item.
A colorkey keyColor, #rrggbb. Returns key: how far the screen's pixels reach from it and where the rest of the picture begins, in the units of similarity, each point's distance, and a similarity and smoothness that fit.
^#?[0-9a-fA-F]{6}$The moment to measure in a video item or a timeline, seconds. Default 0.
x >= 0An item to compare against (an image, or a video with reference_at_seconds); the gap comes back as grade-knob hints.
The moment in the reference video, seconds. Default 0.
x >= 0Points to read the exact color of, as fractions of the picture (0..1).
64Rows or columns to scan; each returns the runs where it is not the picture's ground. One of row or column each.
