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 183924 frames or a Console Time of 51:05.400. First Frame set on the frame Mario appears in the opening cutscene and End Frame set on the frame last midway disappears as it's been collected; after that I decided to beat Bowser at the end.

I use Nintendo Super Famicom Model No. SHVC-001 with "Super Mario World - Super Mario Bros. 4" cartridge model SHVC-MW and GV-USB2 Capture Card. Console and file check during the credits.
