Dynamic Video Rendering Using Static Layer Pre-rendering

Solution Overview

Problem

Existing video rendering technologies are inefficient in dynamically altering and rendering videos, leading to time and resource-intensive processes that cannot be performed at the time of request without causing delays.

Innovation Solution

A method that identifies static and dynamic layers in a video file, renders static layers beforehand, and uses variable definitions to render dynamic layers at the time of request, allowing for efficient customization and rendering of videos with predictable time complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing video rendering technologies are used to dynamically alter and render videos, then video customization is achieved, but the process becomes time and resource-intensive with unpredictable rendering times

Engineering Contradiction:

Improvevideo customizationVSAvoidrendering time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments a video project file into multiple layers, classifying each layer as either static or dynamic. Static layers are pre-rendered into image sequences, while dynamic layers retain their original format with variable components. This segmentation allows the system to process only the necessary dynamic portions at request time, achieving O(1) rendering time while maintaining video customization capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary rendering of static layers during an offline preprocessing step, converting them into image sequences before they are needed. This preliminary action eliminates the need to re-render static content at request time, significantly reducing runtime processing time while preserving the ability to customize videos dynamically based on user information.

Inventive Principle:

AI summary

A method for efficient dynamic video rendering is described for certain implementations. The method may include identifying a file for rendering a video comprising one or more static layers and one or more dynamic layers, detecting, based on analyzing one or more fields of the file for rendering a video, the one or more static layers and the one or more dynamic layers, wherein each dynamic layer comprises a comment that indicates a variable component, rendering the one or more static layers of the file, receiving, from a user device, a request for the video that includes user information, determining, based on the user information, variable definitions designated to be inserted into a dynamic layer, rendering the one or more dynamic layers using the variable definitions, and generating a composite video for playback from the rendered one or more static layers and the rendered one or more dynamic layers.
