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.
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 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.
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.
