Real-Time Video Speed Control via Frame Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video recording systems lack the ability to apply real-time special effects, such as changing the speed of video playback, during the recording process, making it difficult for users to control and modify video speed rates manually while capturing footage.
Innovation Solution
A real-time video special effects system and method that allows users to control video speed rates through a graphical user interface, enabling the modification of video playback speed during recording by adding or removing frames, using frame dropping, frame blending, or frame copying techniques, allowing for fast motion or slow motion effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video speed rate modification is implemented in real-time during recording, then creative control and productivity are improved, but device complexity and processing requirements increase
Solution Approach 1:
The system performs frame rate modification in real-time during the recording process itself, rather than as a post-processing step. By applying frame dropping, frame blending, or frame copying techniques as the video is being captured, the system eliminates the need for separate post-production editing sessions, thereby improving productivity while managing complexity through integrated processing.
2Ease of operation
If manual control of video speed rate is added to the graphical user interface, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system automatically applies the selected frame rate modification technique based on user input without requiring complex manual configuration. Once the user selects a speed rate option through the graphical interface, the system self-manages the frame dropping, blending, or copying process, simplifying operation while maintaining controlled complexity through automated processing.
3Adaptability or versatility
If frame rate modification techniques are implemented, then video special effects capability is improved, but processing time and computational resources increase
Solution Approach 1:
The system maintains continuous video processing throughout recording by seamlessly applying frame rate modification techniques in real-time. Rather than pausing recording to apply effects, the system continuously processes frames at the modified rate, ensuring that special effects capability is achieved without interrupting the recording workflow or adding significant processing delays.
4Loss of time
If real-time frame modification is performed during recording, then post-production editing requirements are reduced, but memory buffering requirements increase
Solution Approach 1:
The system dynamically adjusts memory buffering requirements based on the selected frame rate modification technique. When frame dropping is used, buffer requirements are minimized since frames are selectively discarded. When frame blending or copying is used, the system allocates appropriate buffer capacity to store the necessary reference frames, optimizing memory usage according to the specific processing technique employed.

AI summary
A graphical user interface system and method of recording/editing a video while applying special effects in real time. The interface can be associated with an electronic device including a processor in communication with a camera and a memory unit, or can receive previously prepared video. The native speed rate of the video can be changed, by modifying at least one frame in the video data to create a modified video data at a modified speed rate that is different to the native speed rate. This allows for continuous video recording from the camera or video feed at different speed rates without altering operations or settings. The interface can include time guidelines associated with selectable speed rates, to display which speed rate setting is near a touching finger or pointing device. The guidelines can be activated automatically based on finger location, and can aid in object positioning in a field-of-view.
