Hi , edass!

I try to use this tool before, but there not transparency color background (onli transperant , or only SOLID black , or only SOLID gray , .......)! I need some blend between background colour AND current picture . MTK Windows tool have option thаt blend subtitles whit picture (but not only background color). If you know what is mean R5 parameter in COLOUR menu of MTKSubPatcher , please tell me ! Ecxuse me for my english , please!
