After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60.098813897441 which is the Super Famicom native framerate according to http://tasvideos.org/PlatformFramerates.html and raw video framerate of 60 FPS for a total of 141900 frames or a Video Time of 39:25.000. First Frame set on the frame Mario appears in the opening cutscene and End Frame set on first frame the keyhole gets bigger meaning that I finished SW4. I decided to "finish the job" by beating 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.
