Hello MR.Saxon, what's the music in the background
It's something we found years ago; I'm not sure what it's called!
It would be great if you can make video on MATCH_RECOGNIZE
Good suggestion; I've added it to the list!
hi, Is there any way turn off music please ?, could not follow sometime.
Sorry, the music is part of the video. If this is an issue for you then we do have subtitles. Enable these and mute the video.
Fantastic analyze, please turn off the music, can focus 100%
