Subject: Mangled Subtitle Items                                   Author: Bloody

Problems with certain subtitle items:

  If a window pops up with a "This subtitle item can't be processed" message,
  there may be several reasons why this might happen.

  1. 'Bad' Advanced OCR Setup

  On a few occasions i stumbled upon subtitles where a few items had been added
  later by someone else who used a line spacing of just 1 pixel, which is quite
  unusual for a font at this size (as used with typical DVD subtitles).

  If you suspect that this might be the case (text lines very close together),
  try clicking on the 'Pause' button, then go to the "Advanced OCR Setup",
  change the "Min. Inter Line Height" from 2 to 1 and then click on the
  "Continue" button and see how it goes.

  2. Mangled/changed font colors.

  Sometimes it happens that a subtitle item appears with somehow 'unusual' font
  colors, where the OCR engine is having difficulties identifying single font
  glyphs. If that happens, try clicking on the "Change Text Color" button to
  open a window which will show 4 color squares with checkboxes on top.

  Try to un-check all checkboxes except for the one color that appears to be the
  central 'core' color of the font, then click on "Done" to continue and see how
  it goes.

Generally mangled images:

  If you're converting VobSub subtitles (from .idx/.sub files), it sometimes
  happens that subtitle images appear visibly mangled/corrupt. This depends on
  the program that demuxed (extracted) those files, where the offset values in
  the .idx file which describe the image positions within the .sub file are not
  what SubRip would expect. In this case it usually helps to have SubRip ignore
  those values.

  Try clicking on the "Pause" button, then go to the "Global Options" menu
  and [un-]check the "Use IDX's File Offsets" checkbox. Then click on "Continue"
  and see how it goes. This usually fixes the problem for me (i have that
  checkbox un-checked all the time).
