Video Export Overlay Rendering for Preserving Object and Map Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video export technologies fail to maintain overlays, such as object and geography information, during the conversion of video sections into standard formats like MPEG, MP4, or MOV, necessitating improved methods for embedding and preserving this relevant information.
Innovation Solution
A video export system utilizing a headless browser to play video frames and draw overlays, generating overlaid still images, which are then assembled into an exported video, ensuring overlays like object and geography data are intact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current video export methods are used, then video export speed is fast, but overlays are not preserved or are distorted in the exported video
Solution Approach 1:
The system segments the video export process into distinct phases: extracting individual video frames, rendering overlays separately for each frame, and compositeing them together. This segmentation allows precise control over overlay preservation while maintaining export efficiency through parallel processing of frames.
Solution Approach 2:
The system performs preliminary actions by pre-processing video frames and preparing overlay data before the actual export. Overlays are rendered and positioned in advance for each frame, ensuring they are correctly integrated before final video assembly, which prevents distortion while maintaining speed.
2Manufacturing precision
If overlays are manually integrated into video frames, then overlay quality is high, but processing time increases significantly
Solution Approach 1:
The system replaces manual or sequential mechanical overlay integration with an automated computational system. A processing engine automatically extracts video frames, renders overlays using programmed logic, and composites them together, achieving high integration quality without manual intervention and significantly reducing processing time through automation.
Solution Approach 2:
The system changes processing parameters by operating on individual frame level with controlled overlay rendering parameters. By adjusting parameters such as frame sampling rate, overlay rendering resolution, and parallel processing degree, the system optimizes the balance between integration quality and processing time.
3Measurement precision
If video frames are processed individually for overlay integration, then overlay accuracy is improved, but overall export efficiency decreases
Solution Approach 1:
The system segments the video into individual frames for precise overlay positioning on each frame, ensuring accuracy. Simultaneously, it applies parallel processing techniques where multiple frames are processed concurrently, maintaining export efficiency despite the detailed per-frame treatment.
Solution Approach 2:
The system maintains continuous useful action by implementing a streamlined pipeline where frame extraction, overlay rendering, and compositeing occur in continuous flow without interruptions. This ensures that while each frame receives accurate overlay treatment, the overall process maintains high throughput and export efficiency.

AI summary
Disclosed are systems and methods for exporting videos. In some embodiments, a method includes the steps of: accessing a video section based upon a request; generating a plurality of still images based on a plurality of video frames in the video section; playing the plurality of still images inside a web browser; and drawing one or more overlays on the plurality of still images played inside the container software to generate a set of overlaid still images. In certain embodiments, the exported video is generated based upon the set of overlaid still images.
