I have a lots mkv files. Many has non-styled subs (like srt or regular text) which can be styled by directvobsub settings. but applying a universal style to all videos does not really look good or matches very well. So i want to manually style subs of a specific video. parmanent of course. So what is the way? Do i hav to extract the subtitle 1st OR is there a way to style subs without extracting? Please do tell either way/process if possible and also which one will be easier. Please mention the softwares that i have to use.

I did not raise the point of styled subs. cause i thought it would be too complex to edit. cause styled subs has many different placements, fonts and ... But if u think, it is not that difficult, u can share your thoughts.

Sorry if the answer of my question is already answered in the forum. I thought it might be a bit difficult to find the exact ans in this huge subforum. so please be generous with this newbie.
