Video to Atari 2600 rom

This html page shows a video (must be named videoplayback.mp4) and at the end of the page it dumps some text it must be transformed into a file like "macrodiana.txt". It needs some manual fixing like change the name of the macros to "MAC macroname", or put and endm at the end of the file, among other things. In order to play the video it must be accessed locally via an http server like Everything, because of same origin restrictions when accessing the video pixels individually. Then you must assemble the file animonk3.txt with dasm assembler. It must be named to .sb in order to force a particular bankswitching scheme in Stella.
