Headers

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

Response Field Handling Flow

1. Handle Public Response Fields

   Parse and validate the Public Response Fields, checking the status code or response message to ensure the request is successful and error-free.

2. Handle Business Response Fields

   If the Public Response Fields are valid and error-free, proceed with processing the business logic in the Business Response Fields.
