What is the difference between SRT and ASS support?

The skill outlines that while SRT is widely compatible but limited in styling, ASS offers full typesetting capabilities but is primarily supported by the MKV container.

Can this skill help sync subtitles that are early or late?

Yes, it provides specific ffmpeg commands to apply timing offsets and guidance for using Aegisub to shift durations and resolve overlaps.

How do I check for missing fonts in an ASS subtitle file?

This skill provides commands to list MKV attachments and manual inspection steps to identify font requirements in the ASS style lines, ensuring all necessary assets are available for rendering.

How do I change a subtitle language tag using this skill?

The skill includes mkvpropedit and mkvmerge commands to correctly set the language and default flags for subtitle tracks without re-encoding the video.
