After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60 and raw video framerate of 60 FPS for a total of 39248 frames or a Video Time of 10:54.133. First Frame set on the frame before "OK" moves and End Frame set on the frame that "Finish!" appears on screen.

I use Nintendo Switch OLED Model HEG-001 with physical "Mario Kart 8 Deluxe" cartridge Model LA-H-AABPA-USA updated to version 3.0.1. Game footage captured with a generic HDMI Capture Card. Console check during the credits.
