About TXT_QUICKTIME
QuickTime Text, often called QTText, is Apple's native format for creating text tracks in QuickTime videos. It's a simple text file that can include timestamps and some basic styling descriptors using text-based tags. It was commonly used for adding subtitles, chapter markers, and other timed text to videos within the Apple ecosystem.
About SSA
SubStation Alpha (SSA) is the predecessor to the more feature-rich ASS format. It was one of the first subtitle formats to allow for basic styling, including control over fonts, colors, and text position. While it has largely been superseded by ASS, it laid the groundwork for advanced subtitle scripting and is still supported by many players that support ASS.

Frequently Asked Questions
Does QuickTime Text work outside of Apple products?
Support for QTText is very limited outside of the Apple ecosystem. Players like VLC may have some support for it, but in general, it is not a portable format. For cross-platform compatibility, it's much better to use a universal format like SRT.
Can I style QuickTime Text subtitles?
Yes, QTText supports some basic text styling. You can add descriptors in the file header to define a font, size, and color, and use tags within the subtitle text to apply styles like bold or italic. However, the styling is much more limited than formats like VTT or ASS.
Should I use SSA or ASS?
You should almost always choose ASS over SSA for new projects. ASS is fully backward-compatible with SSA and contains a much larger and more powerful feature set. SSA is primarily of interest for compatibility with very old files or legacy workflows.
What can SSA do that SRT cannot?
Unlike SRT, SSA allows you to define specific styles for your subtitles, such as the font family, font size, primary and secondary colors, and basic positioning on the screen. However, its capabilities are much more limited compared to its successor, ASS.
