Batch Burn in Subtitles, part 2

[Jay123210599]

Is there a way I can batch burn in external and/or embedded subtitles from multiple videos at once while ensuring everything else stays the same (I mean, nothing else is edited or changed from the videos)? Is there a ffmpeg gui for it?

EDIT: I found that FFmpeg Batch Converter could do the trick, but I have a problem. They are the second embedded subtitles in a supported format for my videos, but they are not the same name and the tool can't find them. How do I fix that?
