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 SUB_SUBVIEWER

SubViewer (.sub) is one of the earliest popular subtitle formats. It is a simple, time-based text format. There have been two major versions, SubViewer 1.0 and 2.0. Version 2.0, which is more common, uses a '[region]' section to define metadata and then lists subtitles with timestamps. Its simplicity led to wide support, but it lacks any styling features.

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.

My .sub file doesn't work. Why?

The '.sub' file extension is very generic and is used by several completely different and incompatible subtitle formats, including the text-based SubViewer and the image-based VobSub (for DVDs). If your file isn't working, it's likely because your player is expecting a different '.sub' format. Our converter can intelligently distinguish between them.

Is SubViewer still a good format to use?

For new projects, SRT is a much better choice. It's just as simple but has even wider and more reliable support across all modern platforms and players. SubViewer is mostly relevant for compatibility with older files.
