"Lyrics" are not audio tracks so right there I see a problem.
But as you know, anything in the video is, in short a BITMAP and not "objects" you can remove with any ease.
As to replacing sound tracks, again, this varies but you can, with almost all good video editors, drop in your own audio track. So there should be no question about taht.
I'm new at Audio Video editing so here we go.
I currently use an online software called Karaoke Version. This site has Karaoke videos to download AND, what I use, Custom music tracks in which they provide songs with separate instrument tracks. In these tracks I remove the lead voice and guitar then I play guitar and jam with the music.
I have so many songs and I cant remember all the words so I was hoping to find a way to overlay the karaoke videos they offer with my custom instrument tracks. The Karaoke videos they offer are the exact same instrumental tracks used in the custom tracks. CAN I REMOVE VIDEO LYRICS FROM THE KARAOKE VIDEO AND LAY THEM OVER MY MUSIC TRACKS? IF YES HOW AND WITH WHAT?
