Video Frame Cadence Mapping for Transcoding Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing technologies face challenges during transcoding, as the number of video frames before and after transcoding may not match accurately, leading to inefficiencies in video processing and quality evaluation.
Innovation Solution
The method involves obtaining frame cadence information between the source video and the target transcoded video, which represents the video frame correspondence between the two. This information is used to achieve a more accurate processing result of the target transcoded video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video transcoding is performed without frame cadence information, then the transcoding process is simpler and faster, but the video frame correspondence becomes inaccurate leading to processing errors
Solution Approach 1:
The patent applies preliminary action by obtaining frame cadence information before performing video quality evaluation or denoising operations. This pre-acquisition of timing and frame rate data ensures accurate frame correspondence is established upfront, preventing processing errors in subsequent operations without adding complexity to the core transcoding algorithm
2Reliability
If frame cadence information is obtained and used for video processing, then video quality evaluation and denoising accuracy improve, but processing time and computational resources increase
Solution Approach 1:
The patent extracts only the essential frame cadence information (frame rates and timing data) needed for accurate processing, rather than analyzing complete video frame data. This selective extraction maintains high processing accuracy for quality evaluation and denoising while minimizing the computational overhead and processing time required
