About STL

The EBU STL (European Broadcasting Union Sp-ruce Teletext Ltd) format is a professional subtitle format used extensively in television broadcasting and for DVD authoring. It's a binary format that contains not only the text and timing but also a large amount of metadata related to the production, such as program title, episode number, and translation details. It's a robust format designed for professional broadcast workflows.

About TXT

A plain text (.txt) file is the simplest possible format, containing only raw text characters without any timing or styling information. When used in the context of subtitles, it typically represents a transcript of the audio. To be used as subtitles, this transcript would need to be processed by another tool to add the necessary timestamps to sync the text with the video.

Frequently Asked Questions

Is this STL related to 3D printing?

No, this is a common point of confusion. The EBU STL format for subtitles is completely unrelated to the STL (STereoLithography) file format used for 3D models and printing. They just happen to share the same file extension.

Can I open an STL subtitle file in a text editor?

No, most STL files are binary and will not be readable in a standard text editor. They require specialized professional subtitling software to be opened, edited, and converted.

How can I turn a TXT transcript into an SRT file?

This process is called 'timing' or 'syncing'. It requires specialized software where you can load the video and the text file, and then go through the video, marking the start and end times for each line of dialogue. Many professional subtitle editors offer features to help with this process.

When is a plain TXT file useful?

A plain text file is very useful for creating a simple, readable transcript of a video for reference, for search engine optimization (SEO), or as the first step in a translation workflow before the text is timed.
