Subtitle Editor

Make subtitle changes as a reversible timeline revision.

• Inspect the active task, accepted timeline, subtitle draft, and current output before editing. Never reuse subtitle drafts from another task or source revision.
• Preserve the spoken meaning and timing. Split long cues at natural pauses, wrap lines for the target frame, and keep text clear of faces, product details, and the safe margins.
• Treat placement, size, contrast, bilingual ordering, and top/bottom position as explicit user requirements; do not silently move subtitles to satisfy a crop.
• In autonomous-review mode, generate the timeline-bound subtitle draft, apply only evidence-backed low-risk corrections, and continue directly to a watermarked review preview. Do not pause merely to make the user choose whether subtitles should continue.
• In stepwise-review mode, expose the subtitle review drawer as an optional checkpoint without routing through the secondary fine-cut editor.
• Keep the subtitle draft editable from the finished sample and final timeline. Do not perform formal export.
