Full description

subed

subed is an Emacs major mode for editing subtitles while playing the corresponding media file with mpv. At the moment, the only supported formats are:

  • SubRip ( .srt)
  • WebVTT ( .vtt )
  • Advanced SubStation Alpha ( .ass, experimental )
  • Tab-separated values ( .tsv, experimental ) - as exported by Audacity for labels. TSVs are not recognized automatically because it's a common data format, but you can use subed-tsv-mode to turn it on in a buffer.

Features

  • Jump to next (M-n) and previous (M-p) subtitle text.
  • Jump to the beginning (C-M-a) and end (C-M-e) of the current subtitle's text.
  • Merge subtitles with M-m (subed-merge-dwim) and split them with M-. (subed-split-subtitle). If the media file is playing in MPV, use the current playback position. If not, use the relative position in the subtitle text, or other functions listed in subed-split-subtitle-timestamp-functions.
  • Insert subtitles evenly spaced throughout the available space (M-i) or right next to the current subtitle (C-M-i). A prefix argument controls how many subtitles to insert and whether they are inserted before or after the current subtitle.
  • Kill subtitles (M-k).
  • Adjust subtitle start (M-[ / M-]) and stop (M-{ / M-}) time. A prefix argument sets the number of milliseconds for the current session (e.g. C-u 1000 M-[ M-[ M-[ decreases start time by 3 seconds).
  • Move the current subtitle or all marked subtitles (subed-move-subtitles) forward (C-M-n) or backward (C-M-p) in time without changing subtitle duration. A prefix argument sets the number of milliseconds for the current session (e.g. C-u 500 C-M-n C-M-n moves the current subtitle 1 second forward).
  • Shift the current subtitle together with all following subtitles using (subed-shift-subtitles), or shift them forward (C-M-f) or backward (C-M-b). This is basically a convenience shortcut for C-SPC M-> C-M-n/p. This is handy for correcting sync delays where the subtitles are correctly spaced but are offset from the audio.
  • Scale all subtitles or all marked subtitles forward (C-M-x) or backward (C-M-S-x) in time without changing subtitle duration. A prefix argument sets the number of milliseconds for the current session (e.g. C-u 500 C-M-x moves the last [or last marked] subtitle forward 500ms and proportionally scales all [or all marked] subtitles based on this time extension. Similarly, C-u 500 C-M-S-x moves the last [or last marked] subtitle backward 500ms and proportionally scales all [or all marked] subtitles based on this time contraction). This can be extremely useful to correct synchronization issues in existing subtitle files. First, adjust the starting time if necessary (e.g. C-M-f), then adjust the ending and scale constituent subtitles (e.g. C-M-x).
  • Show CPS (characters per second) for the current subtitle.
  • Insert HTML-like tags (C-c C-t C-t, with an optional attribute when prefixed by C-u), in particular italics (C-c C-t C-i) or boldface (C-c C-t C-b).
  • SRT: Sort and re-number subtitles and remove any extra spaces and newlines (M-s). This is done automatically every time the buffer is saved.
  • Trim subtitle overlaps with M-x subed-trim-overlaps. By default, this adjusts the stop time of overlapping subtitles to subed-subtitle-spacing milliseconds before the next subtitle starts. Use M-x customize-group subed to configure trimming to happen automatically when buffers are loaded or saved, which time is adjusted, and how much time to leave between subtitles.
  • Convert between formats with M-x subed-convert.
  • Show the waveform (M-x subed-waveform-minor-mode, off by default) extracted from the media file using ffmpeg with the start/stop positions of the current subtitle and the current position in MPV marked along with the subtitle. Change the "volume" of the waveform (i.e., the visible amplitude) with C-c C-- and C-c C-=. Redisplay the waveform with C-c |. Left/right-click on the waveform to set the start/stop timestamps. If you would like to display the waveform automatically when you open a file, you can add (add-hook 'subed-mode-hook 'subed-waveform-minor-mode) to your configuration.
  • Load word timing data (ex: SRV2) using M-x subed-word-data-load-from-file. This will be used for splitting words at timestamps when available.
  • Use M-x subed-align and aeneas to align your text or subtitles with an audio file in order to get timestamps.
mpv integration (optional)

Using network sockets to control MPV works on Linux and on Mac OS X, but not on Microsoft Windows due to the lack of Unix-style sockets. On Microsoft Windows, you will not be able to synchronize with MPV.

  • Automatically open the associated media file in MPV based on the filename, open a media file manually with C-c C-v (subed-mpv-play-from-file), or play media directly from a URL with C-c C-u (subed-mpv-play-from-url) . You can customize the automatic detection of files by changing subed-video-extensions and subed-audio-extensions.
  • Pause and resume playback without leaving Emacs (M-SPC).
  • Jump to the current subtitle in the MPV player with M-j (subed-mpv-jump-to-current-subtitle). Toggle looping over the current subtitle with C-c C-l (subed-toggle-loop-over-current-subtitle). Control how many seconds to loop before or after the current subtitles by customizing subed-loop-seconds-before and subed-loop-seconds-after.
  • Use C-c . (subed-toggle-sync-point-to-player) to toggle whether the point should move to the currently playing subtitle.
  • Use C-c , (subed-toggle-sync-player-to-point) to toggle whether mpv should seek to the position of the current subtitle when the point moves between subtitles.
  • Subtitles are automatically reloaded in mpv when the buffer is saved.
  • Copy the current playback position as start (C-c [) or stop (C-c ]) time of the current subtitle.
  • Playback is paused or slowed down when a subtitle's text is edited (C-c C-p, subed-toggle-pause-while-typing).
  • Loop over the current subtitle in mpv (C-c C-l).
  • When a subtitle's start or stop time changes, mpv seeks to the subtitle's start time (C-c C-r, subed-toggle-replay-adjusted-subtitle).
  • Move one frame forward or backward (C-c C-f . and C-c C-f ,; pressing , or . afterwards moves by frames until any other key is pressed).

Installation

Installing the subed package from NonGNU Elpa

subed is now on NonGNU ELPA. On Emacs 28 and later, you can install it with M-x package-install subed.

To install it on Emacs 27 or earlier, add the following to your Emacs configuration file:

(with-eval-after-load 'package (add-to-list 'package-archives '("nongnu" . "https://elpa.nongnu.org/nongnu/")))

Use M-x eval-buffer to run the code, use M-x package-refresh-contents to load the package archives, and then use M-x package-install subed.

Sample configuration:

(with-eval-after-load 'subed-mode
	;; Remember cursor position between sessions
	(add-hook 'subed-mode-hook 'save-place-local-mode)
	;; Break lines automatically while typing
	(add-hook 'subed-mode-hook 'turn-on-auto-fill)
	;; Break lines at 40 characters
	(add-hook 'subed-mode-hook (lambda () (setq-local fill-column 40)))
	;; Some reasonable defaults
	(add-hook 'subed-mode-hook 'subed-enable-pause-while-typing)
	;; As the player moves, update the point to show the current subtitle
	(add-hook 'subed-mode-hook 'subed-enable-sync-point-to-player)
	;; As your point moves in Emacs, update the player to start at the current subtitle
	(add-hook 'subed-mode-hook 'subed-enable-sync-player-to-point)
	;; Replay subtitles as you adjust their start or stop time with M-[, M-], M-{, or M-}
	(add-hook 'subed-mode-hook 'subed-enable-replay-adjusted-subtitle)
	;; Loop over subtitles
	(add-hook 'subed-mode-hook 'subed-enable-loop-over-current-subtitle)
	;; Show characters per second
	(add-hook 'subed-mode-hook 'subed-enable-show-cps))
Manual installation

If that doesn't work, you can install it manually. To install from the main branch:

git clone https://github.com/sachac/subed.git

This will create a subed directory with the code.

If you have the make utility, you can regenerate the autoload definitions with

make autoloads

If you don't have make installed, you can generate the autoloads with:

emacs --quick --batch --eval "(progn (setq generated-autoload-file (expand-file-name \"subed-autoloads.el\" \"subed\") backup-inhibited t) \
	(update-directory-autoloads \"./subed\"))"

Then you can add the following to your Emacs configuration (typically ~/.config/emacs/init.el, ~/.emacs.d/init.el, or ~/.emacs; you can create this file if it doesn't exist yet). Here's a configuration example:

;; Note the reference to the subed subdirectory, instead of the one at the root of the checkout
(add-to-list 'load-path "/path/to/subed/subed")
(require 'subed-autoloads)

(with-eval-after-load 'subed-mode
	;; Remember cursor position between sessions
	(add-hook 'subed-mode-hook 'save-place-local-mode)
	;; Break lines automatically while typing
	(add-hook 'subed-mode-hook 'turn-on-auto-fill)
	;; Break lines at 40 characters
	(add-hook 'subed-mode-hook (lambda () (setq-local fill-column 40)))
	;; Some reasonable defaults
	(add-hook 'subed-mode-hook 'subed-enable-pause-while-typing)
	;; As the player moves, update the point to show the current subtitle
	(add-hook 'subed-mode-hook 'subed-enable-sync-point-to-player)
	;; As your point moves in Emacs, update the player to start at the current subtitle
	(add-hook 'subed-mode-hook 'subed-enable-sync-player-to-point)
	;; Replay subtitles as you adjust their start or stop time with M-[, M-], M-{, or M-}
	(add-hook 'subed-mode-hook 'subed-enable-replay-adjusted-subtitle)
	;; Loop over subtitles
	(add-hook 'subed-mode-hook 'subed-enable-loop-over-current-subtitle)
	;; Show characters per second
	(add-hook 'subed-mode-hook 'subed-enable-show-cps))

You can reload your configuration with M-x eval-buffer or restart Emacs.

If you want to try a branch (ex: derived-mode), you can use the following command inside the subed directory:

git checkout branchname
use-package configuration

Here's an example setup if you use use-package:

(use-package subed
	:ensure t
	:config
	;; Remember cursor position between sessions
	(add-hook 'subed-mode-hook 'save-place-local-mode)
	;; Break lines automatically while typing
	(add-hook 'subed-mode-hook 'turn-on-auto-fill)
	;; Break lines at 40 characters
	(add-hook 'subed-mode-hook (lambda () (setq-local fill-column 40)))
	;; Some reasonable defaults
	(add-hook 'subed-mode-hook 'subed-enable-pause-while-typing)
	;; As the player moves, update the point to show the current subtitle
	(add-hook 'subed-mode-hook 'subed-enable-sync-point-to-player)
	;; As your point moves in Emacs, update the player to start at the current subtitle
	(add-hook 'subed-mode-hook 'subed-enable-sync-player-to-point)
	;; Replay subtitles as you adjust their start or stop time with M-[, M-], M-{, or M-}
	(add-hook 'subed-mode-hook 'subed-enable-replay-adjusted-subtitle)
	;; Loop over subtitles
	(add-hook 'subed-mode-hook 'subed-enable-loop-over-current-subtitle)
	;; Show characters per second
	(add-hook 'subed-mode-hook 'subed-enable-show-cps)
	)
straight configuration

If you use straight.el, you can install subed with the following recipe:

(straight-use-package '(subed :type git :host github :repo "sachac/subed" :files ("subed/*.el")))

Getting started

C-h f subed-mode should get you started. This is the parent mode for subed-srt-mode, subed-vtt-mode, and subed-ass-mode. When manually loading a mode, use those specific format modes instead of subed-mode.

Some workflow ideas

Reflowing subtitles into shorter or longer lines

You may want to use set-fill-column and display-fill-column-indicator-mode to show the target number of characters.

Use subed-split-subtitle (M-.), subed-merge-dwim (M-b), and subed-merge-with-previous (M-M) to split lines.

Splitting will use the current MPV position if available. If not, it will guess where to split based on the the number of characters in the subtitle. You can use subed-mpv-jump-to-current-subtitle (M-j) to play the current subtitle manually and use subed-mpv-toggle-pause (M-SPC) to stop at the right time. Use subed-toggle-loop-over-current-subtitle (C-c C-l) if you want to keep looping. subed-waveform-show-current can help you fine-tune the split.

Adjusting timestamps

You can use subed-mpv-jump-to-current-subtitle (M-j) to play the current subtitle manually. Use subed-mpv-jump-to-current-subtitle-near-end (M-J) to jump to near the end of the subtitle in order to test it. Use subed-toggle-loop-over-current-subtitle (C-c C-l) if you want to keep looping automatically. Use subed-mpv-toggle-pause (M-SPC) to stop at the right time.

subed-waveform-show-current or subed-waveform-show-all can be useful for adjusting start and end timestamps. Use subed-waveform-set-start (mouse-1, which is left click) or subed-waveform-set-stop (mouse-3, which is right-click) to adjust only the current subtitle's timestamps, or use subed-waveform-set-start-and-copy-to-previous (S-mouse-1 or M-mouse-1) or subed-waveform-set-stop-and-copy-to-next (S-mouse-3 or M-mouse-3) to adjust adjacent subtitles as well.

You can also manually adjust

  • subtitle start: M-[ / M-]
  • subtitle stop: (M-{ / M-})

A prefix argument sets the number of milliseconds (e.g. C-u 1000 M-[ M-[ M-[ decreases start time by 3 seconds).

Editing subtitles

You can use subed-mpv-jump-to-current-subtitle (M-j) to play the current subtitle and use subed-mpv-toggle-pause (M-SPC) to stop at the right time. Use subed-toggle-loop-over-current-subtitle (C-c C-l) if you want to keep looping automatically.

If you have wdiff installed, you can use subed-wdiff-subtitle-text-with-file to compare the subtitle text with a script or another subtitle file.

Writing subtitles from scratch

One way is to start with one big subtitle that covers the whole media file, and then split it using subed-split-subtitle (M-.).

Another way is to type as much of the text as you can without worrying about timestamps, putting each caption on a separate line. Then you can use subed-align to convert it into timestamped captions.

Resynchronizing subtitles

If you're using subed-waveform-show-current or subed-waveform-show-all, you can use M-mouse-2 (Meta-middle-click, subed-waveform-shift-subtitles) to shift the current subtitle and succeeding subtitles so that they start at the position you clicked on.

To do this with the keyboard, you can use subed-shift-subtitles-to-start-at-timestamp if you want to specify a timestamp or subed-shift-subtitles to specify a millisecond offset.

Exporting text for review

You can use subed-copy-region-text to copy the text of the subtitles for pasting into another buffer. Call it with the universal prefix C-u to copy comments as well.

Troubleshooting

subed-mpv: Service name too long

If subed-mpv-client reports (error "Service name too long"), this is probably because the path to the socket used to communicate with MPV is too long for your operating system. You can use M-x customize to set subed-mpv-socket-dir to a shorter path.

Important change in v1.0.0

subed now uses subed-srt-mode, subed-vtt-mode, and subed-ass-mode instead of directly using subed-mode. These modes should be automatically associated with the .vtt, .srt, and .ass extensions. If the generic subed-mode is loaded instead of the format-specific mode, you may get an error such as:

Error in post-command-hook (subed--post-command-handler): (cl-no-applicable-method subed--subtitle-id)

If you set auto-mode-alist manually in your config, please make sure you associate extensions the appropriate format-specific mode instead of subed-mode. The specific backend functions (ex: subed-srt--jump-to-subtitle-id) are also deprecated in favor of using generic functions such as subed-jump-to-subtitle-id.

News

1. subed news

1.1. Version 1.2.11 - 2022-12-20 - Sacha Chua

  • New commands subed-shift-subtitles-to-start-at-timestamp and subed-move-subtitles-to-start-at-timestamp should make it easier to adjust timestamps without doing msec math.
  • Add workflow notes to README.org.

1.2. Version 1.2.10 - 2023-12-20 - Sacha Chua

  • Add extra line after comments in text output.
  • subed-guess-format can now take a filename.

1.3. Version 1.2.9 - 2023-12-19 - Sacha Chua

  • New ol-subed adds subed: links to Org Mode. To use it, add (require 'ol-subed) to your configuration. Then you can store links with org-store-link.
  • M-mouse-2 (M-middle-click) on a subed waveform shifts subtitles.
  • VTT: msecs are now optional.
  • New command subed-wdiff-subtitle-text-with-file compares subtitle text with a script or other subtitles. It uses the external wdiff tool.
  • subed-subtitle-comment now returns nil when there's no comment.

1.4. Version 1.2.8 - 2023-11-28 - Sacha Chua

  • subed-waveform:

    • M-mouse-1 (M-left click) and M-mouse-3 (M-right-click) now set

    the start or end timestamp and copy it to the previous or next subtitle, respectively. This makes it easier to hold M- down to change timestamps with the mouse or with M-[, M-], M-{, and M-}, navigating between subtitles with M-n and M-p.

    • You can now show waveforms for all the subtitles using M-x

    subed-waveform-show-all. Set subed-waveform-show-all to non-nil if you want this to be the default behavior of M-x subed-waveform minor-mode.

  • Default to keeping MPV open at the end of the file.
  • New hooks: subed-subtitles-sorted-hook, subed-subtitle-merged-hook
  • New function subed-media-file for things like subed-record which can refer to multiple sources in one file.

1.5. Version 1.2.7 - 2023-11-10 - Sacha Chua

  • subed-align: Use current media file even if it's a video, and restore the comments assuming the subtitles are in sequence.
  • add .m4a to the list of media extensions

1.6. Version 1.2.6 - 2023-11-05 - Sacha Chua

New commands and functions:

  • M-J: subed-mpv-jump-to-current-subtitle-near-end
  • subed-waveform:
    • S-mouse-1: subed-waveform-set-start-and-copy-to-previous
    • S-mouse-3 (right-click): subed-waveform-set-stop-and-copy-to-next
  • subed-append-subtitle-list

New option:

  • subed-sample-msecs

Other changes:

  • Update loop after adjusting timestamps
  • Appending or splitting subtitles in VTT files with comments now puts new subtitles before the next comment.

1.7. Version 1.2.5 - 2023-10-15 - Sacha Chua

Ignore MPV socket errors when closing files on remote computers.

1.8. Version 1.2.4 - 2023-09-11 - Sacha Chua

Guess the format when the generic subed-mode is loaded. Also, require svg when subed-waveform is loaded.

1.9. Version 1.2.3 - 2023-06-18 - Sacha Chua

Added subed-waveform, which you can enable with subed-waveform-minor-mode. This makes it easier to review the waveform for the current subtitle so that you can use it to adjust the start or stop time. It requires the ffmpeg executable. Thanks, mbork!

1.10. Version 1.2.2 - 2023-04-09 - Sacha Chua

subed should not autoplay media over TRAMP.

1.11. Version 1.2.1 - 2023-03-21 - Sacha Chua

Adjusting the starting or stopping timestamp (including via merges) should now also update the looping start and stop times.

1.12. Version 1.2.0 - 2023-03-10 - Sacha Chua

I changed subed-mode so that it doesn't add functions to local hooks, because that seems to mess up configuring hooks from your Emacs init file. Please see README.org for recommended code to add to your subed-mode-hook. I decided to suggest each line separately so that it's easier for people to disable specific behaviors instead of hiding it in subed-setup-defaults.

1.13. Version 1.1.0 - 2023-03-07 - Sacha Chua

There are new customizable values for subed-enforce-time-boundaries that affect setting or adjusting the start or stop times if a subtitle will end up overlapping with the previous or next subtitle (based on … …
