Supported Subtitle Formats

Sublandia Editor supports the following subtitle formats for creating, importing and exporting subtitle files:

• SRT
• TTML
• DFXP
• VTT
• ASS

These formats can be used in different subtitle workflows depending on where the final subtitles will be delivered or played.

TTML and DFXP Subtitle Files

TTML and DFXP are structured subtitle formats often used in professional, platform-specific or broadcast-style workflows.

These formats can contain more structured subtitle information than simple text-based formats. They may be required when delivering subtitles to certain platforms, clients or professional systems.

Use TTML or DFXP when your delivery requirements specifically ask for them.

ASS Subtitle Files

ASS is a subtitle format that can support more advanced subtitle styling and positioning than basic formats such as SRT.

Use ASS when your workflow requires subtitle files with more layout or styling-related information, depending on the requirements of the project.

Keep in mind that not every subtitle player or platform displays advanced styling in the same way.

Creating New Subtitle Files

When you create a new subtitle project in Sublandia Editor, you can work with supported subtitle formats such as SRT, TTML, DFXP, VTT and ASS.

Before choosing a format, check what the final file needs to be. If the subtitles are for simple playback, SRT may be enough. If the project has platform, web or professional delivery requirements, another supported format may be more appropriate.

Importing Subtitle Files

You can import supported subtitle files into Sublandia Editor and continue editing them inside your project.

Supported import formats include:

• .srt
• .ttml
• .dfxp
• .vtt
• .ass

After importing a subtitle file, always check that the text, timing and line structure appear correctly. If the subtitle file was created for a different video version, you may need to fix sync or timing issues.

Exporting Subtitle Files

Supported export formats include:

• .srt
• .ttml
• .dfxp
• .vtt
• .ass

Choose the export format based on where the subtitles will be used. Different platforms, players and clients may require different formats.

Before exporting, review your subtitles carefully and make sure the selected format matches the delivery requirements.

Sublandia Project Files: .subpro

Sublandia Editor also supports .subpro project files.

A .subpro file is different from a subtitle file. Subtitle files such as SRT, VTT or TTML usually contain subtitle text and timing for delivery or playback. A .subpro file is used to save and transfer the full Sublandia Editor project.

A .subpro project file can include the project data, video, template and other information connected to the project.

Use .subpro when you want to:

• save a full project backup
• move a project to another device
• continue editing later
• preserve more project context than a subtitle export alone can contain

Subtitle Files vs Project Files

It is important to understand the difference between subtitle files and project files.

A subtitle file is usually the file you deliver, upload or use for playback. Examples include SRT, TTML, DFXP, VTT and ASS.

A project file is used to save the full working project. In Sublandia Editor, this is the .subpro format.

If you only export an SRT file, you have exported the subtitles. If you export a .subpro file, you have saved the broader project data that can help you continue or restore your work later.

Recommended Format Workflow

For a clean subtitle workflow, follow this order:

1. Prepare an MP4 video file.
2. Check the required subtitle delivery format.
3. Create or import subtitles in a supported format.
4. Edit timing, text and subtitle structure.
5. Review the subtitles before export.
6. Export the final subtitle file.
7. Save a .subpro project backup if you need to continue or protect the project.

Using the correct format at each step helps keep the project organized and reduces the risk of errors later in the workflow.
