Real-Time Overwrite of Pre-Recorded Edits in Multi-Camera Video Timeline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multiple-camera video editing techniques are limited in their ability to efficiently overwrite pre-recorded edits in real-time, especially when dealing with multiple camera sources, as they often require manual adjustments and cannot handle non-linear arrangements of video clips.
Innovation Solution
A computer program product that allows for real-time overwriting of pre-recorded edits in a timeline sequence while playing video, using a graphical user interface with multiple monitors to concurrently display video tracks from multiple cameras, enabling features like punch-in and punch-out locations, and jump back functionality for re-editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional multiple-camera video editing techniques are used, then manual adjustments are required for editing, but editing efficiency is reduced and real-time overwriting is limited
Solution Approach 1:
The system automatically performs editing operations by detecting camera source changes during playback and autonomously creating edit points and overwriting timeline content, eliminating the need for continuous manual intervention while maintaining editing control
Solution Approach 2:
The patent replaces manual mechanical editing operations with an automated digital system that monitors camera sources, detects transitions, and programmatically updates the timeline sequence, substituting human manual adjustments with an automated control mechanism
2Adaptability or versatility
If pre-recorded edits are overwritten in real-time during playback, then editing flexibility is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-defining punch-in and punch-out locations in the timeline sequence before playback begins, allowing real-time overwriting to occur within predetermined boundaries without requiring complex dynamic decision-making during playback
Solution Approach 2:
The patent introduces an intermediary control system that acts as a mediator between the playback mechanism and the editing functions, managing the complexity of real-time operations by coordinating camera source detection, edit point creation, and timeline updates through a centralized control layer
3Manufacturing precision
If multiple camera sources are synchronized and edited simultaneously, then video sequence quality is improved, but processing time increases
Solution Approach 1:
The system maintains continuity of useful action by performing editing operations continuously during playback rather than requiring separate processing steps, allowing multiple camera sources to be synchronized and edited simultaneously without additional processing time penalties
Solution Approach 2:
The patent performs preliminary synchronization of multiple camera sources before playback begins, establishing timecode relationships and edit points in advance, which allows simultaneous processing of multiple tracks during playback without increasing overall processing time

AI summary
Techniques and systems for recording video and audio in timeline sequences. In some embodiments, a method involves playing video from a timeline sequence that can include footage from portions of video tracks including at least one pre-recorded edit. In response to a selection of footage from the timeline sequence, the method can involve overwriting at least one pre-recorded edit in the timeline sequence. Each video track can correspond to a respective camera in a multiple-camera source. The footage can include one or more video clips, still images, frames, and moving images. The overwriting can occur while playing the video at a play rate faster than realtime, a play rate slower than realtime, a user-selected playing rate, during video scrubbing, or during realtime playback. The recording may involve a jump back input, and punch in and punch out locations associated with the timeline sequence.
