In case any reader is interested, I attach the sources that Cinfinity uses on the cinelerra website. And an image idea to put on the cover of the YouTube channel's videos.

I attach the gimp file, in case someone wants to modify it.

The n of cinfinity can be done by rotating the c 90 ° or mirroring the r or the n itself by erasing its left part.

Greetings and thanks for your excellent work.
