garret's aegisub scripts

These are automation scripts ("plugins" basically) I've written for the subtitle editor Aegisub.

I do timing and editing, so these scripts mainly help with those. There's nothing ground-breaking and exciting here, just some stuff to make my life easier.

how do i install them

I believe you should just be able to add them via the Automation Manager, or put them in your autoload folder.

Most of them should register themselves with DependencyControl if you have it installed, but I haven't set up a feed, so you won't be able to update them that way.

I'm not bothering with DepCtrl for newer scripts as it's too much red tape/boilerplate imo. sorry about that.

how do i get help

ping me in the GJM discord server (same username) and I'll probably reply eventually. Otherwise, open a github issue.

ie, technically its not my problem if it doesnt work, burns your house down, etc 👍

fundamentally this is just stuff i wrote for myself and threw over the wall in case it could be useful to someone else as well, i will probably try to help though

And now, the scripts, in no particular order:

Dupe and Comment

Duplicates a line and comments out the original.

This lets you:

• quickly create different versions of a line
• see the differences at a glance
• easily revert to the original, even if the undo history is gone

These hotkeys let me have everything related to duplication on one key.

Thanks to Akatsumekusa for helping improve this script.

Chapter Generator

Generates a chapters file that you can mux into your MKV.

Make a new line, starting at the start of your chapter. Put the chapter name in the text, then mark it with chapter, chptr or chap in the effect field.

For example:

Comment: 0,0:00:00.00,0:00:01.00,Default,,0,0,0,chap,Intro
Comment: 0,0:03:12.96,0:03:13.96,Default,,0,0,0,chap,OP
Comment: 0,0:04:43.01,0:04:44.01,Default,,0,0,0,chap,Part A
Comment: 0,0:11:43.02,0:11:44.02,Default,,0,0,0,chap,Part B
Comment: 0,0:21:09.96,0:21:10.96,Default,,0,0,0,chap,ED
Comment: 0,0:22:40.01,0:22:41.01,Default,,0,0,0,chap,Outro

Then run the script and save the file it gives you. You use it in the Chapters section of MKVToolNix (in the Output tab).

tips/useful things to know

• The first letter of the effect can be uppercase if you want.
• The end time of the line doesn't matter, it's not used in the chapters.
• The language is hardcoded to English, but it's not too difficult to edit the script to change it. Just CTRL-F for eng and change the two values.

acknowledgements

Includes code by unanimated to convert from ms to H:MM:SS.mmm (stolen from Significance).

Restyler

Changes the style of selected lines to Default, and converts italic+alignment (\an) values from the script's styles to inline tags. This is meant for restyling crunchyroll scripts that use separate styles like main, top, italics, italicstop, etc.

On a related note, you might like Chrolo's script to change a line's base style without changing how it actually looks.

Check Pre-timing

This script puts stuff in empty dialogue lines (the actor name, and alternating a or b).

This lets you check pre-timed subtitles without actually having a translation. You can't check CPS of course, but you can see whether the lines are lined up properly, whether they match their actor, etc.

It also includes an undo macro, so you can clean up after yourself after making changes.

It ignores lines that already have text in them. If the line only has tags, it puts the text after them. (that way you can see what those tags do to the text.)

Formerly known as A-B, after the alternating a-b it puts in the lines.

K-Timing -> Alpha Timing

Makes doing alpha timing significantly easier, by getting rid of the part where you do alpha timing.

Time the line in karaoke mode, with the "syllables" as the sections of the line you want to appear. Then run the script, and it'll generate some nice alpha-timed lines for you.

The original line will be commented out, so you can go back and change it easily.

Originally created to convert stuff that should've been alpha timed in the first place, but that used a hack with \ko instead.

DependencyControl Global Config

This macro adds additional configuration interfaces for DependencyControl, so you don't have to edit the JSON file.

• Global Configuration: lets you change DependencyControl's behaviour.
• Extra Feeds: lets you provide additional update feeds that will be used when checking any script for updates.

Please see the DependencyControl README for details on the configuration options.

Time format: [number][unit]

• y for years
• d for days
• h for hours
• m for minutes
• s for seconds

so 7d is 7 days, 3d12h is 3 days and 12 hours, 5m30s is 5 minutes and 30 seconds, you get the idea

rationale

There's a line in the DependencyControl README that goes:

DependencyControl stores its configuration as a JSON file in the config subdirectory of your Aegisub folder (l0.DependencyControl.json). Currently you'll have to edit this file manually, in the future there will be a management macro.

That line was there for 7 years and the management macro still didn't exist, so I wrote one myself.

faderer

Lets you as the timer do fade-in/outs without having to bother the typesetter.

Go to the frame before the fade starts, and run the script. Then go to the frame where the fade finishes, and run the script again.

Select whether the fade is to/from Black, White, or Alpha. It'll try to guess from the timings whether you want to fade in or out, and apply the fade.

Includes code by arch1t3cht to get frame-accurate times. Used under the terms of the MIT License.

Em-dash

Lets you: - Append an Em-dash to the selected lines - Replace instances of -- with an em-dash

Also, if you use arch1t3cht's Aegisub: - Insert an Em-dash at the cursor position

because chances are you don't have an em-dash key on your keyboard :)

Select Comments

Tiny utility script. Easier than Subtitle > Select Lines etc.

Song timer

makes song timing into a rhythm game, so you can vibe while you time

bind the script to to e.g. space, and then:

0. tap to initialise (READY)
1. tap to set start time (START)
2. tap to set end time (END) + move to next line (READY)
3. go to 1.

apparently that's what some vhs era groups did for their entire dialogue timing

it's reasonable enough for (rough pass) song timing, especially if you know the song well. probably won't be faster, but will be much more enjoyable

Scenebleed Detector

Finds scenebleeds in the selected lines, and marks them with an effect (bleed).

This is meant in the vein of unanimated's Quality Check script. It's to help spot mistakes, not as your only check.

It has a hardcoded threshold of 500ms.

Consistency assistant

ctrl-c-ctrl-v.lua

i dont remember

Shenanigans

This script makes dialogue motion-tracking shenanigans easier to manage, by splitting them off into a separate file.

First, define a shenanigan file by making a line in the dialogue file with the effect import, and a path to the file as the text.

Like so: Comment: 10,0:00:00.00,0:00:00.00,Default,,0,0,0,import,shenanigans_naga02_08.ass

Then time/edit as normal. When you see a line (or group of lines) that could use a shenanigan, mark each line with shenan some meaningful identifier in the effect field.

The typesetter goes through all the shenanigans, copies them to the shenanigans file, and does all the motion tracking/effects/whatever in there.

Then, at mux time, you run the script, and it replaces the marked dialogue lines with their counterparts from the shenanigans file.

It's good, because if you ever need to go back and change a line, you can do it without having to wade through 516879832 lines of frame-by-frame motion tracking.

Nowadays this can be handled with folds in arch1t3cht's Aegisub, but they weren't invented yet when this script was written.

There are two implementations here: the python one which we actually use in the mux script, and a lua proof-of-concept.

Syllable Splitter

Splits romaji into karaoke syls.

It tries to use the lengths that the Aegisub K-Timing mode would give if you split it manually.

Timings copier

For when you've timed the romaji for a song and just want to copy those timings to the english thats already in the file.

Requires two consecutive equal-length blocks of lines with different styles from each other. i.e. you have your romaji lines, and the english ones directly after, with separate romaji and english styles.

Comment selection

Make the highlighted text into an inline comment. (encloses it in {curly brackets})

Requires arch1t3cht's Aegisub.

i don't think i've ever actually used this lol

Append Comment

pops up a text box for you to write your comment in, and appends it to the line.

i'm not sure i ever used this one either

pos -> an

converts \pos positions into \an alignments

the idea is you click in the general area of where you want, and then the script converts that into eg \an1 \an8 \an6 etc

but it's not really very useful because that's more effort than just typing it, especially on a numpad

Audio Clipper

Makes audio clips of all the selected lines. Output is either stream-copied, or encoded to a format of your choice.

Select the lines you want to clip, and run the script.

By default, makes a folder called audioclipper_output and dumps all the files in there. The filename is the index of the line in your selection. (no thats not very useful)

Needs FFMPEG in your $PATH.

TXT Cleanup

light-purge.lua

Script I wrote for LightArrowsEXE to remove actors and/or linebreaks when exporting to TXT. I think he wanted it to make doing diffs easier, idk

This is an export filter, not a macro. As such, it won't show up in the normal Automation menu- you have to use File > Export Subtitles... and use it from there.
