I Made a PGS Cropper

[wswartzendruber]

I got sick and tired of OCR'ing subtitles. It's error-prone and really only necessary (for most of us) because if we put the original PGS subtitles in, they'll appear crushed for anything that's not a perfect 16:9.

So I studied some kind of reverse-engineered spec sheet on PGS and created this:

https://github.com/wswartzendruber/pgsscale

So far, it's working wonders on Batman: The Animated Series.

It doesn't yet scale, but if there's interest, I can see about hosting binaries. (Or someone else can do so.)

PGSScale 0.1.0
Scales PGS subtitles

USAGE:
pgsscale <INPUT-FILE> <OUTPUT-FILE> --crop-height <PIXELS> --crop-width <PIXELS>

FLAGS:
--help Prints help information
-V, --version Prints version information

OPTIONS:
-h, --crop-height <PIXELS> Height to crop each subtitle frame to
-w, --crop-width <PIXELS> Width to crop each subtitle frame to

ARGS:
<INPUT-FILE> Input PGS file; use - for STDIN
<OUTPUT-FILE> Output PGS file; use - for STDOUT

This utility will crop PGS subtitles found in Blu-ray discs so that they can match any cropping that has been done to
the main video stream, thereby preventing the subtitles from appearing squished or distorted by the player.

EDIT: Updating usage.

Would you please add the capability to individually cut borders too?

I am tired to manually edit time overlapping PGS on upper and lower part of the screen (such as anime ones).

My idea is to split the PGS in upper and lower parts, OCR them separately and them "join" them in a subtitle editor.
