What is an SSA file?

An SSA file contains subtitles written in the Sub Station Alpha subtitle format. It is used to show subtitles alongside an associated video. You can open and edit an SSA file in any text editor. You can use it as a subtitles track in VideoLAN VLC media player, MPlayer, and CyberLink PowerDVD.

Sub Station Alpha is a program that allows you to create custom subtitles for videos. For example, many English-speaking anime fans use Sub Station Alpha to create subtitles for non-dubbed anime.

Subtitles created using Sub Station Alpha are saved in the SSA format. Each SSA file is a plain text file that includes three sections:

  • [Script Info]: Lists the video the SSA file is meant to be used with, the file's author, and other metadata
  • [Styles]: Contains styling information used to set subtitles' font, color, etc.
  • [Events]: Contains subtitle text and timing information

Some other subtitle-creation programs, such as Aegisub and Gnome Subtitles, also allow you to save subtitles in the SSA format. However, at this point, the .ASS (Aegisub Advanced SubStation Alpha) format has largely replaced the SSA format.

How can I validate that my SSA subtitles are formatted correctly?

You can validate that the subtitles your SSA file contains are formatted correctly by uploading the file to the Subtitle Validator available at https://validator.subtitledpro.com/.

How to open an SSA file

You can use an SSA file as a subtitles track in VideoLAN VLC media player (multiplatform), MPlayer (multiplatform), and CyberLink PowerDVD (Windows).

For example, to use an SSA file as a subtitle track in VLC media player:

  1. Open VLC and play the video with which you want to use your SSA file.
  2. From VLC's menu bar, select Subtitle → Add Subtitle File ....
  3. Navigate to and open your SSA file.

To edit the subtitles an SSA file contains, open the file in Aegisub (multiplatform), Microsoft Notepad (Windows), Apple TextEdit (Mac), or any text editor.

What is an SSA file?

An SSA file is a game data file used by Children of the Nile (CotN), a city-building game set in ancient Egypt. It contains data used to load a CotN campaign, which consists of linked scenarios. Players can create SSA files using CotN's Campaign Editor.

More Information

Children of the Nile, also known as Immortal Cities: Children of the Nile, is a game in which players construct buildings, issue edicts, and tend to citizens' needs in an ancient Egyptian city. Players can play singular city-building scenarios, or they can play a linked series of scenarios known as a campaign.

Campaigns are saved in SSA files. For example, the game includes a default Grand Campaign, which is saved in an SSA file. Players sometimes create custom campaigns and share them with each other over the Internet. These campaigns are also saved as SSA files.

How to open an SSA file

You can open an SSA file in Children of the Nile (Windows). To do so, place the file in the game's Campaigns directory, located in one of the following places:

  • ~/​Documents/​Tilted Mill/​Children of the Nile/​Campaigns
  • C:/​Program Files (x86)/​Tilted Mill/​Children of the Nile/​data/​Campaigns

Then, open Children of the Nile and select Campaigns → Other Campaigns. The campaign your SSA file contains should appear in the campaign list.
