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 60 FPS for a total of 168781 frames or a Video Time of 46:53.017. First Frame set on the frame Mario appears in the opening cutscene and End Frame set on the frame that Peach appears outside of Bowser's Clown Car.

Checkpoint grab at 25:10 (run time) by rules intentional hit and intentional death followed, then I finished the level and replayed it again. Also Kaizo Larry, lol wtf?

I use Super NES Control Deck Model No. SNS-101 with "Super Mario World - Super Mario Bros. 4" cartridge model SHVC-MW and GV-USB2 Capture Card. Console during the credits.
