New — Bilingual subtitles (free)
Author Belgian-style bilingual subtitles: one language on top, the other below, on one shared timing — exactly two lines, one language per line. Combine two tracks into a bilingual track, set a track's second language (split editor spell-checks each language on its own), swap the two languages top ↔ bottom, or translate a track to bilingual directly.
New — Lock tracks
Lock a track to protect it from accidental edits — text, timing, timeline drag/resize, merge/split and delete are disabled until you unlock it.
Fixes
More robust cloud / local-server translation (MTPLX, Ollama, LM Studio, …): reasoning-model "thinking" and server stats footers are stripped so translations parse cleanly.
