SupMover

SupMover - Shift timings and Screen Area of PGS/Sup subtitle

Usage

Usage:  SupMover <input.sup> [<output.sup>] [OPTIONS ...]

OPTIONS:
  --trace
  --delay <ms>
  --move <delta x> <delta y>
  --crop <left> <top> <right> <bottom>
  --resync (<num>/<den> | <multFactor>)
  --add_zero
  --tonemap <perc>
  --cut_merge [CUT&MERGE OPTIONS ...]

CUT&MERGE OPTIONS:
  --list <list of sections>
  --format (secut | (vapoursynth | vs) | (avisynth | avs) | remap)
  --timemode (ms | frame (<num>/<den> | <fps>) | timestamp)
  --fixmode (cut | (delete | del))

Options

• --trace
  • Print contents and structure of input file segments
• --delay
  • Apply a milliseconds delay, positive or negative, to all the subpic of the subtitle, it can be fractional as the SUP speficication have a precision of 1/90ms
• --resync
  • Multiply all the timestamp by this factor, this can also be supplied as a fraction
• --move
  • Shift the windows position of all subpic by the inputed parameters (the image data is left untouched).
  • Position is clamped to the screen edges so that windows are always fully contained within the screen area.
• --crop
  • Crop the windows area of all subpic by the inputed parameters.
  • This is done losslessly by only shifting the windows position (the image data is left untouched).
  • Crop functionality is not exstensivelly tested when multiple Composition Object or Windows are present or when the windows are is outside the new screen area, a warning is issued if that's the case and i strongly advise to check the resulting subtitle with a video player, also handling of the Object Cropped flag and windows area bigger than the new screen area is not implemented, a warning is issued if needed
  • If both --move and --crop are selected, the crop is performed after the move.
• --delay + --resync
  • If both modes are selected the delay will be adjusted if it comes before the resync parameter, for example if the program is launched with --delay 1000 --resync 1.001 it will be internally adjusted to 1001ms, instead if it's launched with --resync 1.001 --delay 1000 it will not
• --add_zero
  • Some media players (especially Plex) don't correctly sync *.sup subtitles. They seem to ignore any delay before the first 'display set'. This option adds a dummy 'display set' at time 0 so subsequent timestamps are correctly interpreted.
• --tonemap
  • Change the brightness of the subtitle applying the specified percentage factor to all the palette's luminance value, similar to https://github.com/quietvoid/subtitle_tonemap , the percentage must be specified as a decimal value with 1 as 100%, it can be bigger than 1 to increase brightness
• --cut_merge
  • allows to cut subtitle and optionally, if more sections are specified, to merge the cuts into a single subtitle file with the subsequent cuts shifted to have them begin at the end of the previous section. It is possible to personalize its functionality with some options
    • --list: specifies the space-separated list of sections, --format and --timemode can be used to further configure the parsing of this list. The list must be contained inside double quotes
    • --format: the format type of the list
      • secut: uses the same format as SECut. eg 1000-2000;3000-4000
      • vapoursynt or vs: uses the same format as vapoursynth split sintax, additionally if --timemode is set as frame the range will be treated inclusively at the start and exclusively at the end. eg [1000:2001] [3000:4001]
      • avisynth or avs: uses the same format as avisynth trim sintax. Eg (1000,2000) (3000,4000)
      • remap: uses the same format as Vapoursynth-RemapFrames ReplaceFrameSimple. Eg [1000 2000] [3000 4000]
    • --timemode: allow to specifies how to read the values of the sections
      • ms
      • frame: if selected a framerate MUST be specified, as a fraction like 24000/1001 or as a number like 23.976
      • timestamp: if selected the sections MUST be in the format hh:mm:ss.ms and can't be used with --format vapoursynth
    • --fixmode: allow to specify how to treat subtitles which are not fully contained in a section
      • delete or del: delete the subtitle if not fully contained inside a section
      • cut: cut the subtitle so that it is fully contained in the section
  • if no further option is specified it will works like secut so like the following command line --format secut --timemode ms --fixmode delete
