====== Subtitleeditor ======

In Debian GNU/Linux 13 Trixie you can find the **subtitleeditor** packages which contains the graphical program of the same name.

For the workflow I'm interested in (adding descriptive subtitles to travel footage), I need a few simple features:

  * Insert a title at the current position in the video.
  * Move the title forward or backward in the timeline.
  * Extend or shorten the duration.

The program allows you to assign **shortcut keys** to various functions. These are the configurations I have implemented:

^ I  | /ClipboardPlugin/clipboard-paste-at-player-position  |
^ 1  | /VideoPlayerManagement/video-player/skip-backwards-frame  |
^ 2  | /VideoPlayerManagement/video-player/skip-forward-frame  |
^ Q  | /VideoPlayerManagement/video-player/play-pause  |
^ A  | /VideoPlayerManagement/video-player/skip-backwards-very-short  |
^ S  | /VideoPlayerManagement/video-player/play-current-subtitle  |
^ Z  | /AdjustTimePlugin/remove-from-start-and-from-duration  |
^ X  | /AdjustTimePlugin/add-to-start-and-to-duration  |
^ C  | /AdjustTimePlugin/remove-from-duration  |
^ V  | /AdjustTimePlugin/add-to-duration  |

The workflow is something like this:

  - Open the .srt subtitle file: menu File => New or File => Open
  - Open the video file: Video => Open
  - Add the waveform (real or dummy): Waveform => Generate Waveform from Video or Waveform => Generate Dummy Waveform.
  - Press Q to play the video, press it again to stop at the desidered point.
  - Press I to insert the clipboard content as a subtitle at current play position
  - Press V and C to adjust the subtitle duration.
  - Press Z and X to adjust the subtitle position.
  - Click a specific subtitle into the tiles list.
  - Press S to play the selected subtitle.
  - Press A sto skip backward the play position.

**NOTICE**: When you press the I key, the subtitle will be inserted **after the current subtitle** in the titles list, beware that also the play position is after the current subtitle, otherwise timing and position will be messed.
