I request an encoder takes a look at this script and tries stuff. For use with BizHawk while running (SNES) Push-Over and a TAS of it, and creating a video file of it.
The basic idea is to get rid of screen transitions, and the address I found seems to indicate the moments where the game screen is visible and G.I. Ant can be seen going through doors. I've ran the test function and I can't find any errors in the logic I used, and this address really does look like this magic screen transition detection value.
This script is intended for encoder use. I don't really touch encoding myself, so I'm hoping the script works fine fresh off this page. Might be jarring that it goes straight from G.I. Ant going in one door and immediately the screen's at the other door he's going out of.
Enough explanation. Here's hoping it works as advertised, and all you have to do is run BizHawk, this script, and activate whatever encoding function is necessary to produce some kind of media file.
