Not an issue, just a question

Hello, I'm sorry to be bothering you,
I've been working on a video project for a few month and just found your library,
Sadly, I just do not understand how your compression works.

Where should the file to be compressed be uploaded from.
Right now I have a few .h files that contain hundreds of XBM converted frames, but I have a reached a maximum of around 955 frames on an ESP32,

How should I format my file to be able to compress it?
Thanks in advance :)
