About CSV
CSV (Comma-Separated Values) is a simple text format for storing tabular data. In the context of subtitles, it's often used for translation workflows or bulk editing. Each row in the CSV file can represent a subtitle cue, with columns for the start time, end time, and text. It's easy to open and edit in any spreadsheet program like Excel or Google Sheets.
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 use a CSV file directly as a subtitle?
No, a CSV file cannot be used directly as a subtitle track in a video player. It's an intermediate format. You would need to convert the CSV file into a standard subtitle format like SRT or VTT after you have finished your edits or translations.
What is the best use case for CSV subtitles?
CSV is ideal for workflows where non-technical users need to edit or translate subtitle text. Giving a translator a simple spreadsheet is much easier than asking them to edit the strict syntax of an SRT or VTT file. It's also great for programmatically managing subtitle data.
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.
