Converting sup to png with timecode batch wise

[Ninelpienel]

Hey, I'm using the "Images with time codes in file name" export fuction of Subtitle Edit to prepare my subs for a ocr with Abbyy. My problem is that when you want to ocr many files at the same time it's really annoying to open and export every single file seperately.

Is there a program or tool that can convert the sup files to pngs with timecode in the file name batch wise?
