I need to add some black rectangle, because video is some kind of broken, very nasty 5px gray bar on the bottom. :\
I wanna make crop -6 then addborders 6, but i don't wanna loose video quality is there any option such as "direct stream copy" or can i have appropriate MeGUI profile?

Just encode from the source again, but be sure to crop out the 6 offending pixels. You'll lose quality or need to increase bitrate if you encode it again.

Hi!Great Live Performance 2005 DVD. My R1 version has no such problem, does yours? 'Fumbling Towards Ecstasy' is just code name of mkvmerge version. ~~


As you can see in MediaInfo log there are "encoding settings" so i think i need to set everything the same way to not lose in quality and this is the main problem i don't know how set it perfectly the same. :(
