The author describes what he's doing in the comments to the video you linked.
I basically look for dark pixels aligned horizontally, put a box around them and call them letters.
He also mentions
If you like i could share the source code.
...so if you're still curious, you know what to do.

I would... search for dark pixels aligned horizontally. More precisely, search for pixels within a certain brightness distance from black, at aligned within, say, 80% from horizontal. If you want more detail, ask the poster. It's his algorithm, we'd just be guessing.
