After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60 which is the Switch 2 default framerate and raw video framerate of 60 FPS for a total of 28386 frames or a Video Time of 7:53.100. Frame set on the frame Lakitu's lights turn Green and End Frame set on the frame that the "F" of "Finish!" appears on screen.

I use Nintendo Switch 2 Model BEE-001 with digital "Mario Kart World" version 1.4.1, Nintendo Switch 2 Pro controller and a generic HDMI Capture Card.
