  • render_factor

    Type : string

    Required : No

    Description :

    The render_factor parameter controls the quality and speed of the colorization process. Higher values produce more accurate and detailed results but may take longer to process, while lower values result in faster processing with slightly less detailed colorization.

    Possible Values :
    • 20 (Default) - Standard colorization quality and speed.
    • 7 to 40 - The range of values for adjusting the quality and processing time.
    Default Behavior :
    • If not specified, the default value is 20, offering a balance between quality and speed.

    Example : render_factor = 30

    Important :
    • 1 credit will be charged for each processing, regardless of the render factor.
    • Higher render_factor values result in better colorization but may increase processing time.
