After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60.098813897441 which is the SNES native framerate according to http://tasvideos.org/PlatformFramerates.html and raw video framerate of 30 FPS for a total of 2421 frames or a Console Time of 1:20.680. First Frame set on the frame Mario appears in the opening cutscene and End Frame set on the frame the Switch is shown pressed.

I use Super NES Control Deck Model No. SNS-001 with "Super Mario World - Super Mario Bros. 4" cartridge model SHVC-MW and GV-USB2 Capture Card. Console check at the end of the run.
