Solution Overview
Problem
Current video recording systems lack the ability to apply special effects, such as speed modifications, in real-time during the recording process, requiring post-production editing and being device-dependent, which is time-consuming and resource-intensive.
Innovation Solution
A real-time video special effects system that includes a camera, processing unit, and graphical user interface, allowing users to control and modify the video speed in real-time by adding or removing frames, enabling fast motion or slow motion effects without the need for hardware support or post-editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video speed modification is performed in post-production editing, then special effects can be achieved, but production time and costs increase
Solution Approach 1:
The system applies speed modification processing during the recording phase rather than after recording completes. The processing unit modifies video frames in real-time as they are captured, performing the special effects action preliminarily before the recording session ends, thereby eliminating the need for separate post-production editing time
Solution Approach 2:
The video recording system performs speed modification processing internally during recording without requiring external post-production software or equipment. The processing unit integrated into the recording device handles the frame addition/removal operations autonomously, making the system self-sufficient and eliminating dependency on separate editing workflows
2Adaptability or versatility
If professional camera apps with preset frame rates are used, then slow motion and speed up effects can be created, but the system complexity and device requirements increase
Solution Approach 1:
The system implements a simplified frame rate modification approach that uses basic frame addition or removal operations rather than complex multi-parameter preset systems. By applying only the essential speed modification function without additional features like variable frame rates or multiple preset modes, the system achieves speed effects with minimal complexity
Solution Approach 2:
The system creates speed effects by copying existing frames or removing frames from the original video stream rather than generating entirely new content. This copying approach allows speed modification to be achieved through simple duplication or deletion operations on existing frame data, reducing the need for complex processing algorithms
3Productivity
If frame rate conversion is performed using traditional methods, then video speed effects are achieved, but the processing requires post-recording operations
Solution Approach 1:
The system performs frame rate conversion continuously during the recording process rather than as a separate batch operation after recording. The processing unit operates continuously alongside the camera, modifying frames as they are captured and maintaining the video stream without interruption, thereby eliminating idle editing time
Solution Approach 2:
The system combines the recording function and speed modification processing function into a single integrated workflow. Instead of separating recording and editing into distinct phases, the processing unit merges frame capture and frame rate conversion operations, allowing both functions to occur simultaneously during the recording session
Data Source
AI summary
The present technology is a video recording system and method of recording a video while applying special effects in real time prior to and/or while recording. The system includes a processing unit in communication with a camera and a memory unit. The processor receives a raw video data at a native speed rate from the camera or remote video stream, and an input from an interface. The system determines if the native speed rate of the raw video data is to be changed, and if so then modifies at least one frame in the raw video data to create a modified video data at a modified speed rate that is different to the native speed rate. The system then generates an output video recording data and writes it to memory. This allows for the continuous recording of video from the camera or video feed at different speed rates without altering camera operations or settings.
