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.
About SMI
SMI or SAMI (Synchronized Accessible Media Interchange) is a format developed by Microsoft for subtitles in Windows Media Player. It uses an HTML-like syntax, which allows for basic styling and formatting of the subtitle text. It also has features for including multiple language tracks in a single file. Its usage has declined significantly with the wane of Windows Media Player.

Frequently Asked Questions
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.
Is SMI still used?
SMI is largely considered a legacy format. While it was popular in the early 2000s, especially in some Asian markets, its proprietary nature and the rise of open standards like VTT have made it uncommon for modern content.
What are the advantages of SMI?
Its main historical advantage was its ability to include multiple languages in one file and its use of familiar HTML-like tags for styling, which was accessible to web developers at the time. However, modern formats have surpassed its capabilities.
