Resource: VideoThumbnail
Information about a video thumbnail.
| Fields |
name |
string
The resource name representing the video thumbnail, of the form "projects/*/videoThumbnails/**" (e.g. "projects/earthengine-legacy/videoThumbnails/").
|
expression |
object (Expression)
The expression to compute. Must evaluate to an ImageCollection.
|
videoOptions |
object (VideoOptions)
Options for the animation.
|
fileFormat |
enum (VideoFileFormat)
The output encoding in which to generate the resulting video thumbnail. Currently only GIF is supported.
|
grid |
object (PixelGrid)
An optional pixel grid describing how the images computed by expression are reprojected and clipped.
|
VideoOptions
Basic options for generating videos.
| JSON representation |
{
"framesPerSecond": number,
"maxFrames": integer,
"maxPixelsPerFrame": string
} |
| Fields |
framesPerSecond |
number
The frame rate of the exported video. Must be a value between 0.1 and 120. Defaults to 5.0.
|
maxFrames |
integer
The maximum number of video frames to compute and export. This is a safety guard to prevent you from accidentally starting a larger export than you had intended. The default value is 1000 frames, but you can set the value explicitly to raise or lower this limit.
|
maxPixelsPerFrame |
string (Int64Value format)
The maximum number of pixels to compute and export per frame. This is a safety guard to prevent you from accidentally starting a larger export than you had intended. The default value is 1e8 pixels, but you can set the value explicitly to raise or lower this limit.

Methods |

|
Creates an ID that can be used to render an image containing an animation of multiple images from a collection. |
