Syncing Debug Video and Log

Patent JP7781117 has been granted by JPO. It describes a dev system (image 1 below) in which a Switch generates game footage of dev build with a superimposed progress bar and frame number (#120 in image 2). A PC then reads the bar and number in the video (via OCR) to synchronize it with debug logs.

Drawing from US20250061044: FIG. 1 is a view showing a non-limiting example configuration of a game development support system according to a first embodiment.
Drawings from US20250061044: FIG. 7 is a view showing a non-limiting example game screen including an identification image. FIG. 8 is a view showing a non-limiting example identification image included in a game screen.

A simplified version omits the frame number, but applies alternating colors to the progress bar (image 1 below) for synchronization purposes.

The system makes debugging easier by syncing and showing the video footage and log file side-by-side (image 2 below).

Drawing from US20250061044: FIG. 5 is a view showing a non-limiting example viewing screen displayed on the display device of the information processing apparatus shown in FIG. 1.
Drawing from US20250061044: FIG. 18 is a view showing a non-limiting example identification image included in a game screen according to a second embodiment.

Note: All images above are from US publication 20250061044, which is still pre-grant, for readability.
