Subtitles full of junk lines?

Players and editors display long lines badly — breaking lines at word boundaries keeps captions readable. Merging short fragments removes flicker, and consistent casing or encoding (UTF-16 for Windows editors, Latin-1 for legacy players) makes your file work everywhere. Every cleanup runs 100% in your browser: nothing is uploaded.
