Pass selection

  • 1st pass (Detect) - detect subtitles and write subtitles mask and additional information to files
  • 2nd pass (Remove) - read masks and additional information and remove subtitle
  • Temp folder - very important parameter! The filter will write to this folder and will read from it!

    • First pass - subtitles detection

  • Detection Area
  • Automatic - Automatiñ mode means working with whole frame; Uncheking this radiobutton allows yuo to set area manually; smaller area means much faster work
  • Left - left border of detection area
  • Right - left border of detection area
  • Top - top border of detection area
  • Bottom - bottom border of detection area
    • Coardinates are measured in pixels from top left corner

  • Subtitle Preset Subtitle type. Please, look only on contrast between cont and outline colors ano common video quality. If no variand is applicable, detecion parameters could be set manually.
  • Subtitle Outline Contrast - Minimal contrast between subtitle and outline. Lower contrast meaòû that more pixels will be marked as subtitles.
  • Subtitle Sensivity - Subtitle detection threshold. Lower ("High quality") values means more "strict" checking and less pixels will be marked.

    • Second pass - subtitles removing
  • Blur/Compensation balance - Blur threshold. If you decrease this parameter it could lead to better subtitles removal on scene changes but decrease the quality of removal for another cases
  • Subtitle outline compensation -If subtitles have "weak" edges (i.e. half-transparent shadow or glow), some pixels from subtitle edges could be losed. Morphological operation "Dilation" is used for removing this artefacts. Lower values means less dilation count and some pixels can be leaved by remover. Higher values means losing of "non-subtitle" pixels.
