Dynamic Virtual Camera System for Real-Time Play-Recording Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional play videos of TRPGs and manipulation-type games are monotonous due to lack of visual changes, leading to viewer boredom, and creating engaging videos requires additional time and technical expertise.
Innovation Solution
A system that records play videos in real time by switching between long-shot views and character-specific angles within a virtual space, using a first terminal for video creation and multiple connected terminals for player interaction, allowing dynamic video creation during gameplay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional play screens are recorded directly, then the video creation process is simple, but the video becomes monotonous with few noticeable visual changes
Solution Approach 1:
The system dynamically switches between multiple camera angles (long-shot position and avatar-capturing positions) during video recording. The shooting position is not fixed but changes based on gameplay events, allowing the video to capture both overall game context and important character actions, thereby eliminating monotony while maintaining automated recording
Solution Approach 2:
The video recording system is segmented into multiple virtual cameras positioned at different locations. Instead of a single monotonous viewpoint, the system divides the visual field into multiple perspectives (long-shot for overall context, close-up for character actions) and selectively records from different segments based on gameplay events
2Difficulty of detecting and measuring
If multiple camera angles are implemented to reduce monotony, then visual engagement improves, but the system complexity increases
Solution Approach 1:
The system automatically determines when to switch between camera angles based on predefined gameplay events (character actions, dialogues, battles). The video recording system serves itself by autonomously selecting appropriate shooting positions without requiring manual intervention or complex post-processing editing
Solution Approach 2:
Multiple virtual cameras are pre-positioned at optimal locations (long-shot position and various avatar-capturing positions) before the game begins. The system prepares multiple perspectives in advance and simply selects from these pre-configured options based on gameplay events, avoiding the need for complex real-time camera positioning or post-recording editing
3Loss of information
If video recording captures all gameplay details, then completeness is improved, but viewer boredom increases due to lack of visual variation
Solution Approach 1:
The recording system dynamically adapts its viewpoint based on gameplay events. During important moments (character actions, dialogues, battles), it switches to avatar-capturing positions for detailed views. During transitional or less critical moments, it uses long-shot positions for broader context, maintaining visual interest while preserving all essential gameplay information

AI summary
For real-time creation of a play-recording video that is not boring, the system includes: a first terminal having a first display section; second terminals each having a second display section; a storage section holding display data of a virtual space and avatars of characters; an avatar display controller which displays avatars within the virtual space according to input operations on the second terminals; a shooting position setter which sets, as a shooting position, a long-shot position or an avatar-capturing position for capturing a character's avatar according to an input operation on the first terminal; a virtual space imager which creates an image taken with a virtual camera at the shooting position; first and second screen display controllers which display the image on the first and second display sections; and a play-recording-video creator which sequentially records a play screen and creates a video.
