Dual Frame Display Tool for Video Clip Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-end digital cameras and video recorders lack the capability to embed time codes or number frames, making manual synchronization of video media clips during post-production a laborious process, especially when camera frame capture timing is not synchronized with display time codes.
Innovation Solution
A tool with two video frame displays indicating odd and even numbered frames within a second, which synchronizes clips by displaying a single frame number when synchronized and adjacent odd and even numbers when not, along with a timeline display for hours, minutes, and seconds, aiding in creating coherent sequences in post-production editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single video frame display is used to show frame numbers, then the display is simple, but the frame numbers become completely blurred during frame transitions making the time code useless for synchronization
Solution Approach 1:
The display is segmented into two separate video frame displays: one showing odd-numbered frames and the other showing even-numbered frames. This segmentation ensures that during frame transitions, each display shows a stable frame number without blending or blurring, as each display updates only on its designated frame type.
Solution Approach 2:
The solution adds a temporal dimension to the display system by creating alternating update cycles for odd and even frame displays. Instead of a single display updating continuously (causing blur), two displays update alternately in time, eliminating the blur effect while maintaining continuous frame number information.
2Ease of manufacture
If manual synchronization methods are used for low-end cameras without time codes, then no additional hardware is needed, but the post-production process becomes painstaking and laborious
Solution Approach 1:
The synchronization tool enables operators to perform self-service synchronization by providing real-time visual feedback through the dual frame displays. The system automatically detects when frame numbers are stable and synchronized, allowing operators to create timeline markings without requiring complex post-production software or expert synchronization skills.
Solution Approach 2:
The invention replaces the mechanical/manual synchronization process with an automated electronic display system. Instead of manually tracking frame counts and making adjustments during post-production, the electronic dual-display system automatically presents synchronized frame information, eliminating the painstaking manual methods previously required.
3Duration of action of moving object
If the camera aperture remains open during frame transitions, then continuous video capture is maintained, but the frame numbers on display become completely blurred
Solution Approach 1:
By segmenting the frame number display into two separate displays (odd and even), the system eliminates the blur problem without needing to close the aperture. Each display updates only on its designated frame type, ensuring clear, stable frame numbers are always visible even while the aperture remains open for continuous capture.
Solution Approach 2:
The system changes the display update parameter from continuous single-display updates to alternating dual-display updates. This parameter change allows the aperture to remain open continuously while the display system alternates between showing odd and even frame numbers, maintaining both video capture continuity and frame number clarity.

AI summary
A video media clip synchronization tool has a timeline display which indicates, from its beginning, the running time of a video shooting event in hours, minutes and seconds. The tool also has two video frame displays which sequentially indicate frame numbers within a current second of the video shooting event. One of the video frame displays indicates the odd numbered frames within the current second of the video shooting event and the other of the video frame displays indicates the even numbered frames within the current second of the video shooting event. A single video frame number is displayed when the clips of video media and the video frame displays are synchronized. Adjacent odd and even video frame numbers are simultaneously displayed when the clips of video media and the video frame displays are not synchronized.
