REST Resource: projects.locations.videoThumbnails

    • A VideoThumbnail resource provides information needed to generate a video thumbnail from an ImageCollection.

    • Key properties include the expression to compute the ImageCollection, video options like frame rate and maximum frames, and the desired output file format.

    • Currently, only GIF is supported as an output file format for video thumbnails.

    • The VideoOptions specify parameters for the animation, such as framesPerSecond , maxFrames , and maxPixelsPerFrame .

    • The create method allows generating an ID to render an animation from a collection of images.

    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.

 : 
 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.

    VideoFileFormat

    Selects a video file format in which to encode a sequence of images.

    Enums
    VIDEO_FILE_FORMAT_UNSPECIFIED Unspecified.
    MP4 MPEG-4 Part 14 format.
    GIF Animated GIF.
    VP9 WEBM/VP9

    Methods

    create

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