Hi,
I have Manjaro Gnome version and i have Brasero installed and want to make ISO copies of my DVDS but when i make an ISO copy of some of my DVDS the subtitles are very transparent and i want to change this to make them non-transparent how should i go about this?
kind regards
Hi @NSS and welcome 
Let me guess, your DVD has vobsub subtitles? Vobsubs are literally bitmap images which are usually transparent. I guess there is not much you can do, since these subtitles are pictures of text.
An option would be GitHub - elizagamedev/vobsubocr: Blazingly fast and accurate DVD VobSub to SRT subtitle conversion which converts the pictures into real text.
