Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data is transmitted without compression, then transmission quality is maintained, but transmission bandwidth consumption increases
Solution Approach 1:
The patent changes the parameter of video data representation by converting video frames from RGB color space to YUV color space, where the luminance component (Y) is preserved at full resolution while chrominance components (U and V) are subsampled. This parameter transformation reduces bandwidth consumption by approximately 50% while maintaining perceived visual quality, as the human eye is more sensitive to luminance variations than chrominance variations.
2Quantity of substance
If video data is compressed, then transmission bandwidth consumption is reduced, but transmission quality deteriorates
Solution Approach 1:
The patent applies different quality levels to different components of the video data. The luminance component (Y) is transmitted at full resolution with high quality, while the chrominance components (U and V) are subsampled at lower resolution. This local quality differentiation allows the system to reduce overall bandwidth consumption while maintaining the critical luminance information that the human eye is most sensitive to, thereby preserving perceived transmission quality.
3Reliability
If video data is transmitted in original format, then transmission quality is maintained, but processing time increases
Solution Approach 1:
The patent performs color space conversion from RGB to YUV and applies chrominance subsampling during the video encoding stage, which is done in advance before transmission. This preliminary action transforms the video data into a more efficient representation format, reducing the amount of data that needs to be processed during transmission and playback, thereby reducing overall processing time while maintaining acceptable quality.
4Quantity of substance
If video data is compressed, then storage space is reduced, but image quality deteriorates
Solution Approach 1:
The patent changes the parameter of color representation by using YUV color space with chrominance subsampling (e.g., 4:2:0 format) instead of full RGB color space. This parameter change reduces the number of pixels that need to be stored by approximately 50% for the chrominance components, significantly reducing storage space requirements while maintaining perceived image quality, as the human visual system is less sensitive to chrominance details.
5Reliability
If video data is stored in original format, then image quality is maintained, but storage space consumption increases
Solution Approach 1:
The patent applies local quality differentiation by storing the luminance component (Y) at full resolution to maintain critical image quality, while storing the chrominance components (U and V) at reduced resolution through subsampling. This approach significantly reduces storage space consumption by approximately 50% for the chrominance data while preserving the luminance information that is most important for perceived image quality.

AI summary
Provided are a video processing method and apparatus, and a device and a storage medium. The method comprises: when it is detected that an editing reference track of a video to be processed moves out of a video editing window, displaying a mask in a bottom region of the video editing window, wherein the editing reference track comprises a video track and/or an audio track; and then, on the basis of a time axis on the video editing window, displaying, on the mask, the editing reference track of said video, wherein the editing reference track displayed on the mask is used for assisting a user with editing said video in the video editing window. It can be seen that, according to the video processing method provided in the embodiments of the present disclosure, when a video editing window moves out of an editing reference track, the editing reference track can be re-displayed in the form of a mask, such that the impact on video processing performed by a user is reduced, and the user experience is improved.
