Merge two subtitle files into bilingual, or style a track: font, colour, outline and position, all WYSIWYG.
Bilingual merge and adjust, ASS / VTT style presets, per-value style slots, in-place and bulk timeline fixes, and a live preview that is literally the exported file.
Creators making bilingual or styled subtitles, encoding groups, and teams that need accessible captions.
