I bought a German blu-ray with no English subtitles and I can only find a recompressed copy of the same program with hard coded subs. I would like to rip the subs from the recompressed version to overlay them on my higher quality blu-ray copy.

I understand that SubRip (1.56.1) is the usual goto for this kind of thing (though I'd be glad to hear of alternatives) and I nearly have it working. However, when I go to set the "Inter-line options" in the "Video file viewer" window to tell it how high each line is, it will not let me increase the "Height" beyond 44 (pixels?). It looks like the actual line height required so that letters don't get cut off and interpreted as "open regions" would be at least 50.

I see that in the main "SubRip 1.56.1" window there is the setting "Options->Advanced OCR Setup->Line Setup->Max. Line Height", but if I try and set it any larger than 45 it gives me a dialog window saying "Warning: < 0 ; 45 >".

Having to re-encode at a lower resolution just to satisfy this arbitrary line height restriction seems kind of silly and will no doubt make the OCR more error prone as the text borders won't be as crisp. Am I just out of luck on this, or is there a better way forward?
