Embodiment Construction

[0016] like figure 1 As shown in FIG. 1 , it is a flow chart of the method for supporting dynamic parameter effect plug-ins provided by Embodiment 1 of the present invention.

[0017] For each effect plug-in, there are corresponding parameters, and the meanings of each parameter in different effects are also different. These parameters are stored in the parameter tree of the corresponding effect in a tree structure, and correspond to a position one by one. , which is called the parameter address of the parameter in the parameter tree, and the parameter address uses the variable Index to mark the order of the parameter in the same-level parameters. The special effect node is the root node of the parameter tree, and each parameter corresponds to a leaf node in the parameter tree.

[0018] S101. Acquire parameter tree information of special effects.

[0019] S102, if adding a new dynamic node, when we want to add a new node, first find the root node of the effect according to t...

Abstract

The embodiment of the present invention discloses a method and device for a special effect plug-in supporting dynamic parameters. The method includes the following steps: obtaining the parameter tree information of the special effect; finding the information of the parent node where the dynamic parameters are located; if adding a dynamic node, creating a A new leaf node is added to the parameter, or in the case of deleting a dynamic node, the node is removed from the parameter tree. Through the embodiment of the present invention, a complete set of mechanisms is provided for realizing the dynamic addition or deletion of parameters of special skills, so that the added dynamic nodes and static nodes have the same editing function, and the key frame curve can also be adjusted, thereby Increased interactivity and operability of effect plugins.

Description

technical field [0001] The embodiments of the present invention relate to the fields of nonlinear editing and editing software and post-video and audio special effect processing and synthesis software, and in particular to a method and device for a special effect plug-in supporting dynamic parameters. Background technique [0002] In non-linear editing and editing software and video and audio post-processing and synthesis software, we often need to develop some corresponding special effect plug-ins in order to cooperate with users to complete some specific functions. Due to the diversity of editing materials and the increase in the complexity of functions, more interaction with users is often required to obtain more accurate results. Therefore, some associations can be dynamically added (deleted) in the special effects plug-in The adjustment parameters have become more and more important. [0003] Considering that each specific special effect has a complete function, and th...
