Version 1.0.1 (2013-06-29)

A few fixes and some basic MP4 container scene change support.

  • Add scene change support for MP4 container by using synchronisation points.

Version 1.0.0 (2011-04-03)

Finally here is version 1.0.0 after 7 years of developments.
I'm no sure at this point if I will continue to work on this project, even though there is still lots of features or improvements that I would like to add. There is at least two reasons for that: Firstly I've moved to Linux as my main OS, and secondly the developement environment used for VSS is getting very old (Delphi 7) and in newer releases there is no more free available version. Of course any developer is welcome to join and continue the project which I remind is opensource from the start.
No new big features in this version but a lot of small bugs fixed.

  • Implemented feature request #2998396 : Open most recent project on startup
  • Fixed bug #2988478 : Display problem with “Translate” dialog this dialog is now re-sizable and should display correctly.
  • Fixed shortcut overwrite problem when loading preset
  • Fixed bug #2970734 : Double click on stop time change the next subtitle.
  • Fixed unicode option change : auto save project
  • Fixed undo delete action : mark project as dirty
  • Fixed translate dialog : now use “translate all subtitles” when there is no VO file
  • Fixed VO file loading : always clear current VO file before trying to load new VO file which can be empty
  • Added jsplugin function VSSCore.GetTextSelectionStart() : Return the position of the first selected character in the text.
  • Added jsplugin function VSSCore.GetTextSelectionLength() : Return the number of characters that are selected.
  • Added jsplugin function VSSCore.GetAudioCursorPosition() : Return the position of the yellow audio cursor in ms.
  • Fixed spell checking handling of typographic characters (non-breaking spaces, quotes, dashes, apostrophe …) (patch by spirit)
  • Fixed SSA/ASS export : make sure there is a default style when saving as SSA or ASS format. (reported by spirit)
  • Added *.FLV to the open video file dialog filter.
  • Improved GUI splitter display (based on code by Anders Melander)
  • Added a check for AVI file with lots of key frame (if >=100 consecutive KF then disable scene change display)
  • Fixed some possible crash when no adequate splitter can be found

Version 0.9.22 (2010-03-14)

This version bring some bug fix and more options for the creation of the translation template (File>Translate…)
A little reminder, VisualSubSync's website is editable (register now), so everyone is welcomed to add some content (tutorials, description of your usage and workflow, detailed mockup for a feature request, …). If you need any help, let me know.

Version 0.9.19 (2009-07-27)

In this version, there is now the possibility to display a second subtitle file for translation purpose (no edition allowed).

Also several subtitles can be merged together in the original version column.
You can use the View>Show/Hide Reference VO menu item to show or hide the original version file.
This feature (and others below) is a great contribution by kickaha from

Thanks again to Sixe for the bug report.

Version 0.9.9 (2007-02-24)

This is a kind of release contest version before 1.0, so don't forget to report any bugs, thanks.
There is two big improvements in this version: the subtitles video preview and the SSA/ASS style editor.
With SSA/ASS support getting more complete, it's important to know that you can directly create your project in SSA/ASS format by setting the extension accordingly in the project creation window.
There is also improvements in the timing mode with the space bar, now you can time an existing transcript and VSS will try to ensure a characters per seconds target, a minimal subtitle duration and a minimal blank duration between subtitles.
Also good to remember, if you experience a crash, don't forget to check the backup directories (Preferences… > General > Backup)
Here is a more complete changelog :

  • Improved subtitles video preview by using a custom VSFilter version. Saving subtitles is not needed anymore to have an updated preview. If playing is stopped you will need to play the subtitle again to update the preview. If you pause the video, you can see modifications in real time.
  • Added SSA/ASS style editor
  • Added new configurable shortcuts to set subtitle start/stop time during “live timing” : Set subtitle start time, Set subtitle stop time, Set subtitle stop time / go to next
  • Improved timing mode with space bar, there is now a set of options to modify existing subtitles instead of creating new one.
  • Added pause button
  • Added volume trackbar
  • Added configurable shortcut to toggle between normal and timing mode : Toggle between normal and timing mode
  • Application settings are now saved in user application data directory if in read only mode
  • Improved screen font size handling
  • Detached video window state is now saved per project
  • Added support for reading UTF-16 Unicode files
  • Added configurable shortcut (“next error”) to go to next error.
  • Added a “general” JavaScript plugin with 2 functions (OnSubtitleModification and OnSubtitleSelection). It is currently used to show statistics (can be disabled by deleting jsplugin\general\general_plugin.js)

Thanks to Guilamu, Sixe, Thyresias and Stef for suggestions and testing.

This is mainly a bug fix release. Though there is one new feature, when making selection or modifying existing subtitles in the wav displayer, the mouse position is constrained in some way to avoid subtitles overlapping. If you don't like this behaviour you can disable it in the preferences (last checkbox in “General” tab).
Bug fix and small changes list:

Version 0.8 (2005-04-08)

The big new thing in this release is of course the experimental karaoke support. To create a karaoke, you first synchronize the lyrics as normal subtitles. Then you separate each syllable by ”/” and you right click in the subtitle list and choose “Create karaoke”. You can now adjust each syllable in the waveform part. By double clicking on a karaoke syllable, you select that syllable, and you have access to common VSS function like shift start/stop time, play and next but at the syllable level.
You work in the .srt file format, when you have finished, you can export the final version of the file to ssa by using the new “Export to SSA…” function.
Using karaoke in a .srt file is not valid even if vobsub/vsfilter play it.

Here is a more complete list of changes:

  • Experimental karaoke support
  • Added “Show frame at cursor”, “Show stop frame” and “Show start frame” hotkeys
  • Export to SSA
  • Export to WAV + html
  • Show a little message in status bar when we receive a suggestion
  • Fixed 8 bits wav loading

Version 0.7 (2005-01-09)

In this release, I've added some live subtitling functions. Now, when you're playing your video file, you have keys to create subtitles. For example, in timing mode, when you press the space key, VSS store the current playing time and when you release it, it creates the subtitle, so you can do a quick timing with only one key. If you want a bit more flexibility, in the HotKeys settings, you also have 3 new hotkeys :
- “Start new subtitle”
- “Stop current subtitle”
- “Stop current sub and start new sub”

Here is a more complete list of changes:

  • Added live subtitling function
  • Improved dynamic subtitle selection (more visual feedback, now works when you are before or after a subtitle)
  • Added “Clear selected” suggestion context menu (on Aspirantnemo request)
  • Added “Auto save when playing start” option in backup settings (on Mr kb request)
  • Added a warning for some bad wav file
  • Fixed a bug in srt loading with empty lines
  • Fixed playing of .vob/mpeg2 files again

Version 0.6 (2004-12-24)

The new toy in this version is the support for JavaScript plugins. By making little scripts you can add your own error detection/correction functions. Old ones have been converted to plugins with some improvements, for example the “too long line” function now include a “smart” line splitter. There is also a plugin to check french typography. Of course you can send me any plugin you have made.
For easier plugins developpement, you can download the JavaScript 1.5 Reference >> here <<
A big thanks to the nice guys of the Delphi JavaScript Bridge project.

Version 0.4 (2004-07-15)

You load your transcript in the text pipe, you select a sentence in the WAV display part, you select the matching text in the text pipe and you choose “Add subtitle from pipe”. You have the option to automatically delete the text you added from the pipe, it's why it's called a pipe, text his moving out as you add subtitles.
