Video Synthesis Encoding Mode Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video synthesis methods using high compression ratios result in significant video loss and lower definition due to limited memory in smart terminals, making it necessary to develop a method that balances video synthesis and quality.
Innovation Solution
A video synthesis method involving real-time acquisition of second video data, first encoding using a specific mode, synthesis with existing videos, and subsequent second encoding using a different mode to achieve a target video with reduced loss and high definition, employing distinct encoding modes and processes for real-time and non-real-time encoding.

Engineering Contradiction Analysis
1Quantity of substance
If a high compression ratio is used in video encoding, then the video file size is reduced, but the video quality and definition deteriorate
Solution Approach 1:
The patent divides the video encoding process into two separate stages: first encoding the photographed video data, then encoding the synthesized video data. Each stage uses appropriate encoding parameters for its specific purpose, avoiding the need to use a single high compression ratio that would compromise quality.
Solution Approach 2:
The patent applies different encoding parameters for different encoding stages. The first encoding uses parameters optimized for real-time processing, while the second encoding uses parameters optimized for final quality. This allows the system to achieve both small file size and high video quality by changing parameters at different stages.
2Productivity
If real-time encoding is performed on photographed video data, then the processing speed is improved, but the encoding quality may be compromised
Solution Approach 1:
The patent separates real-time encoding from final encoding into distinct stages. The first encoding stage processes photographed video data in real-time with appropriate speed optimization, while the second encoding stage focuses on quality optimization without real-time constraints.
Solution Approach 2:
The patent performs preliminary encoding of the photographed video data before synthesis, preparing it in real-time for subsequent synthesis and final encoding. This preliminary action enables real-time processing while maintaining the capability for high-quality final output.

AI summary
The present disclosure provides a video synthesis method, apparatus, computer device and computer-readable storage medium, which the method includes: acquiring a first video; capturing second video data photographed in real time; performing first encoding on the second video data to obtain an encoded video; synthesizing the first video and the encoded video to obtain synthesized video data; and performing second encoding on the synthesized video data to obtain a target video. By means of the method, there is less loss in the obtained target video frames and a relatively high definition of the video frames.
