Syntax

public class ApiKeyframe

Constructors

ApiKeyframe(double, double, string)

Initializes a new instance of the ApiKeyframe class.

Declaration

public ApiKeyframe(double timestamp = 0, double sceneScore = 0, string imageBase64 = "")

Parameters

Type	Name	Description
double	timestamp	Presentation timestamp of the keyframe, in seconds from the start of the video.
double	sceneScore	Scene-change score that triggered this keyframe, in the range [0.0, 1.0]. Higher values indicate a more pronounced scene change relative to the preceding frame. The first keyframe of a video is always reported as 1.0: the start of a video is a scene boundary by definition, so that score is not a measured frame-to-frame comparison.
string	imageBase64	The extracted frame as a base64-encoded JPEG image. Empty when the request set include_images = false.

Properties

ImageBase64

The extracted frame as a base64-encoded JPEG image. Empty when the request set `include_images = false`.

Declaration

public string ImageBase64 { get; protected set; }

Property Value

string
