Header

Field	Required	Type	Description
ailabapi-api-key	YES	string	Application API KEY. Get API KEY

Body

Field	Required	Type	Scope	Default	Description
version	YES	string	v2		Version.
image_target	YES	file
mode	NO	integer	0 1 2 3 4	0	Camera movement mode. 0: Push forward shot, default with flowing effect. 1: Wide-angle camera movement. 2: Hitchcock camera movement. 3: Swing camera movement. 4: Bounce camera movement.
long_side	NO	integer	[0, 1920]	960	The length of the video's longer side for rendering. The larger the value, the longer it takes, growing exponentially in powers of two.
frame_num	NO	integer		90	Video frame rate (without speed change). The larger the value, the longer it takes, increasing linearly.
fps	NO	integer		30	Video frame rate. frame_num/fps determines the video duration.
use_flow	NO	integer	-1 0 1	-1	Whether to apply the flow effect. Enabling the flow effect typically increases processing time by approximately 20% to 30%. -1: The algorithm determines whether to enable the flow effect based on the mode value. 0: Forcefully disable the flow effect. 1: Forcefully enable the flow effect.
speed_shift	NO	string		Constant Speed	Video Curve Speed Variation. More Details Each pair of adjacent values represents the x and y values of a control point. x range [0, 1]: Progress from the beginning to the end of the original video. y range [0.1, 10]: Speed rate. Each pair of adjacent control points represents a speed change curve, with the curve function being a trigonometric function.

speed_shift

For example, 0,1,0.5,4,0.5,4,1,1 represents the curve in the following diagram.

Response

Processing Flow

1. Handle Public Parameters:

   First, parse and validate the Public Parameters, checking the status code or response message to ensure the request is successful and no errors are present.

2. Handle Business Parameters:

   If the public parameters are valid and no exceptions are found, proceed to process the business logic in the Business Parameters.
