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 SRT
SRT (SubRip Text) is the most common and widely supported subtitle format. It's a simple plain text file that contains sequential numbers for each subtitle, start and end timestamps, and the subtitle text itself. Its simplicity and universal compatibility make it the go-to choice for most web videos, streaming platforms, and local media players.

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.
Can I add colors or change fonts in an SRT file?
No, the SRT format does not support any styling. It is a plain text format. If you need styling, you should use a more advanced format like VTT or ASS.
What does 'hearing impaired' mean in SRT files?
Subtitles for the deaf and hard of hearing (SDH) often include descriptions of non-verbal sounds, like '[door slams]' or '[music playing]'. While SRT can contain this text, VTT is often better for more structured accessibility features.
