It only outputs text files with the special symbols used for animations. The main idea of it was that the pretty stuff is there to make your writing process more fun while letting you copy everything/save it as a .txt to send to people in a more serious conventional format.
If you want to record gifs of the text animations/the process of you writing it:
- get this free app https://www.screentogif.com/
- turn off windowed mode in textreme settings
- launch screentogif in recording mode, select area to record, fps etc. etc.
- cut off the ends so that it loops
- export what you got as gif
- fiddle with it here until the file is of a reasonable sizehttps://ezgif.com/optimize
Hope that helps!
