Problems solved by technology

In related technologies, usually separate special effects rendering modules are set for the shooting scene and the editing scene, but the special effects in the two scenes cannot be interoperable.
Developers need to develop a set of special effects for the shooting scene and a set of special effects for the editing scene. The respective special effect modules cannot be used interoperably in the two scenes, resulting in a waste of resources

Embodiment 1

[0031] Such as Figure 1 to Figure 4 As shown, the present invention discloses a device and method for special effect rendering of video. The adopted technical solution includes a receiving module 1, which receives user rendering instructions and video frames to be rendered, and analyzes the rendering instructions Determining the special effects corresponding to the video frame and the action time interval of each special effect, and confirming module 2, for analyzing the rendering instruction, determining the special effects corresponding to the video frame and the action time interval of each special effect, rendering Module 3, the general rendering module draws the special effect into the received frame buffer object, performs adaptive adjustment on the special effect according to the characteristics of the frame buffer object, merges the module 4, and outputs the module 5, the receiving module 1 is connected to the confirmation module 2, The confirmation module 2 is connec...

Abstract

The invention discloses a special effect rendering device and method for a video, relates to the technical field of Internet, and aims to solve the problems that a developer needs to develop a set of special effects for a shooting scene and a set of special effects for an editing scene, and respective special effect modules cannot realize intercommunication use under two scenes, so that resource waste is caused; through mutual cooperation of the receiving module, the confirmation module, the rendering module, the merging module and the output module, special effect visual sense of different video scenes can be the same, consistent experience is provided for a user, in addition, the design scheme can develop special effect modules for different video scenes, the cost is saved, iteration is facilitated, and through a merged GLSL program, the user experience is improved. Rendering of the video frame is realized; compared with the prior art, the operation times of the GLSL program are reduced, and the rendering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a device and method for special effect rendering of videos. Background technique [0002] In this era of micro-shooting, people hope to use software with video editing functions in mobile terminals such as mobile phones and tablet computers to convert the scattered photos and images of themselves and their family and friends into interesting dynamic videos and share them with family and friends. In this conversion process, rendering video frames is an important link. [0003] Rendering, the final step in CG (besides post-production, of course), is the stage where the image is finally made to fit the 3D scene. English is Render, and some people call it shading, but generally Shade is called shading, and Render is called rendering. Because the two words Render and Shade are two completely different concepts in 3D software, although their functions are similar, they are diffe...
