Video Preview Interface Dynamic Frame Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video preview interfaces provide limited information about video content, leading to a poor user experience as users can only view a static frame image, which does not adequately represent the video file.
Innovation Solution
A method and apparatus that select a preset number of video frames from a video file to generate a target video file, which is then displayed in a video preview interface, allowing users to play the frames in sequence and reverse order to provide a more comprehensive representation of the video content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a static frame image is displayed in the video preview interface, then the device complexity is reduced and the preview image can be generated quickly, but the user experience deteriorates because users get very little information about the video content
Solution Approach 1:
The patent segments the video file into multiple video frames and selects a first preset number of frames to display in the preview interface. This segmentation allows the system to provide dynamic video content information while maintaining manageable complexity by only displaying a subset of frames rather than the entire video.
Solution Approach 2:
The patent introduces dynamic playback capability where selected video frames can be played in sequence and reverse order. This dynamic feature transforms the static preview image into an interactive video preview, enabling users to obtain more comprehensive video content information without requiring the entire video to be loaded or played.
2Loss of information
If a target video file containing multiple video frames is generated and displayed in the video preview interface, then user experience is improved by providing more video content information, but the loss of time increases due to frame selection and processing
Solution Approach 1:
The patent performs preliminary frame selection by pre-determining a first preset number of video frames to extract from the video file before display. This preliminary action optimizes the balance between providing sufficient video content information and minimizing processing time, as the frame selection is done in advance based on preset criteria rather than on-demand.
3Loss of information
If video frames are selected and processed to generate a target video file, then more comprehensive video content information is provided, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The patent extracts only the necessary video frames (a first preset number of frames) from the complete video file for display in the preview interface. This extraction approach provides comprehensive video content information through dynamic playback while avoiding the complexity of processing and storing the entire video file, thus resolving the contradiction between information completeness and processing complexity.

AI summary
The embodiments of the present application provide a method and an apparatus for releasing a video file, which are applied to a server. The method comprises obtaining a video file to be released; selecting a first preset number of video frames in the video file to be released; generating a target video file using the selected video frames; determining a target display position for the target video file in a video preview interface; and storing the correspondence between the target display position and the target video file so that a first terminal logging in the server plays the target video file at the target display position in the video preview interface based on the correspondence. As can be seen, since the first terminal plays the target video file at the target display position in the video preview interface, the user can get more information about the content of the video file to be released from the target video file, so that the user experience is improved.
