This is using an old version of chrome web engine to be compatible with windows 7 (Chrome/96.0.4664.93) this means some websites will not work properly with it and it has security vulnerabilities that have not been fixed so be sensible where you take it on the internet! use at your own risk!
This does not capture video in the normal sense it captures the URL’s of media files and then offers to download them which means it does not capture streaming services, just on demand videos. There is no UI to start the capture of a playing video and this being a closed source program is pirating GPLv3 build of FFMPEG binaries and distributing them illegally without attribution or one thought for the license conditions.
