Authorizations

​
ailabapi-api-key
string
header
required

API Key for authentication

Body

multipart/form-data
​
version
string

Version.

Example:

"v2"

​
image_target
file
​
mode
integer

Camera movement mode. <li>0: Push forward shot, default with flowing effect.</li> <li>1: Wide-angle camera movement.</li> <li>2: Hitchcock camera movement.</li> <li>3: Swing camera movement.</li> <li>4: Bounce camera movement.</li>

Example:

"0"

​
long_side
integer

The length of the video's longer side for rendering. The larger the value, the longer it takes, growing exponentially in powers of two.

Example:

"960"

​
frame_num
integer

Video frame rate (without speed change). The larger the value, the longer it takes, increasing linearly.

Example:

"90"

​
fps
integer

Video frame rate. frame_num/fps determines the video duration.

Example:

"30"

​
use_flow
number

Whether to apply the flow effect. Enabling the flow effect typically increases processing time by approximately 20% to 30%. <li>-1: The algorithm determines whether to enable the flow effect based on the mode value.</li> <li>0: Forcefully disable the flow effect.</li> <li>1: Forcefully enable the flow effect.</li>

Example:

"-1"

​
speed_shift
string

Video Curve Speed Variation. <li>Each pair of adjacent values represents the x and y values of a control point.</li> <li>x range [0, 1]: Progress from the beginning to the end of the original video.</li> <li>y range [0.1, 10]: Speed rate.</li> <li>Each pair of adjacent control points represents a speed change curve, with the curve function being a trigonometric function.</li>
