Usually we often confused when our video files are not integrated with the sub-title we do not want ... so, this is a solution for those who experience it. but unfortunately only support the Matroska video files or mkv file ..
and then select the media file first, also you click add button again to input SRT file.
we can replace our sub-title by unchecked the original sub-title text, like this picture
you can also edit your output file with click browse, if you has finished click on start muxing... then enjoy your language sub-title on your favorite movie :)
