Longer target phrasing may require an earlier line break without moving the source cue boundary. In the target track, Prefer direct clauses and preserve intentional register rather than expanding every implicit subject. Both writing systems render left to right, but player layout still needs a visual pass.
Decision signals
- Source language: Spanish (es), written with Latin.
- Target language: English (en), written with Latin.
- The workflow preserves cue IDs and timing first, then makes visible text and line-break changes under human review.
Prepare the Spanish cue track
Spanish articles and clitic pronouns should remain attached to a readable phrase when cues split. Preserve opening question and exclamation marks and check dialogue dashes deliberately. Correct uncertain names, numbers, and speaker changes against the recording before asking a translation model to transform the text.
Shape readable English subtitles
Prefer direct clauses and preserve intentional register rather than expanding every implicit subject. English cue breaks usually read best at phrase boundaries, not immediately before short function words. The source review policy was different: Keep grammatical gender, formality, and regional vocabulary consistent across the whole subtitle track. Keep a stable mapping back to the source cue so reviewers can compare meaning without losing the original timing context.
Run bilingual timing and rendering QA
Review apostrophes, quotation style, contractions, and sentence case after line wrapping. Both writing systems render left to right, but player layout still needs a visual pass. On the source side, Longer target phrasing may require an earlier line break without moving the source cue boundary. Watch the result with audio at normal speed, inspect every speaker change, and export only the reviewed track rather than an unexamined model response.
Boundaries to keep visible
- The page documents a Spanish-to-English review workflow; it is not an accuracy score or a promise that every configured model, account, or deployment accepts the pair.
- Keep source cue timestamps as the initial anchor, but permit a human subtitle editor to revise segmentation when target-language readability would otherwise fail.
