MKS (Matroska subtitle) is a subtitle file format that is part of the Matroska multimedia container format. ASS (Advanced SubStation Alpha) is a subtitle format that allows for advanced styling and positioning of text.
While there is currently no known software tool capable of directly converting subtitles from .mks streams to .ass (or any other) subtitle files, there is a promising workaround. You can extract the subtitles using MKVToolNix or a similar MKV video tool, a process that is indeed possible, and then modify or convert them using standard subtitle software like Subtitle Edit.

Understanding mks and ass file formats
MKS is a Matroska Subtitle file, typically used to store subtitle tracks within Matroska multimedia containers (MKV). These files are not standalone subtitle files but are usually embedded within video files. ASS (Advanced SubStation Alpha) is a popular subtitle file format that supports advanced styling, positioning, and effects, making it widely used for anime and other video subtitles.
Why convert mks to ass?
Converting MKS to ASS allows you to extract subtitle tracks from Matroska containers and use them as standalone, editable subtitle files. This is useful for editing, translating, or using subtitles with different media players.
How to convert mks to ass
Since MKS files are usually embedded in MKV containers, the process involves extracting the subtitle track and saving it as an ASS file. Here’s how you can do it:
Step 1: Extract the MKS subtitle track
- Use MKVToolNix (free, cross-platform) to open your MKV file.
- In MKVToolNix GUI, load your MKV file.
- Uncheck all tracks except the subtitle track (usually labeled as MKS or ASS).
- Click Start multiplexing to extract the subtitle track as an MKS file.
Step 2: Convert MKS to ASS
- If the extracted MKS file contains ASS subtitles, simply rename the file extension from .mks to .ass.
- If the MKS contains another subtitle format (like SRT), use a subtitle editor such as Aegisub to open the file and export it as File → Export → Advanced SubStation Alpha (.ass).
