  • Subtitle rendered into video is unreadable due to missing contrast

    I have ripped an old DVD "Haven" with subtitles rendered into the video and it works nicely.
    But, the text is unreadable due to lack of contrast between text and picture
    as shown on the attached example.
    If I rip the DVD with remux, the subtitles are OK readable.
    I wonder why there is a difference between the two modes.
    Seems like DVDFab somehow makes a poor choice of font and typesetting.

    The problem is that the background layer of the pixels that make up the sub image are not being rendered (the ones that are normally white or yellow) or are possibly being rendered as transparent. I tried a different DVD and the subs were fine, so it may be some incompatibility with the way the subs are authored on that disc. To check it, the developers will need all the IFO files from the original disc and a decrypted portion of one of the VOB files of the movie. You can produce this by using DVD Copy mode Main Movie and selecting only a single chapter of the movie to be processed. Send me a PM when you have all the above zipped and I will send you upload instructions.

        signals Sorry, but I can't figure out if you have seen my response - and if the OneDrive link was usable.

          The link worked fine, checking it now.

          I have duplicated the problem and will send it to the developers.
