You can split or join lines without running AI sync again. Youka Fix line breaks editor with a video preview, selectable split points, and Join lines controls ## Open the editor 1. Open a completed Project in **Studio**. 2. Select **Fix line breaks** beside **Manual Sync**. The editor shows every timed line. A **May wrap on screen** label marks a line that may be too long for the current design. ## Start a new line Select the word that should begin the next line. Youka moves that word and every word after it into a new line while preserving the existing word timing. Use the play button beside a line to preview that exact boundary before you continue. ## Join two lines Select **Join lines** between two adjacent lines. Youka combines their words into one timed line. If the result is too long for the current design, the editor shows **May wrap on screen** so you can choose a better split point. ## Undo, redo, and finish * Select **Undo** or **Redo** to review your recent line-break changes. * Select **Done** when the grouping looks right. Changes are auto-saved. The words and their timing stay unchanged; only the line grouping is edited. Use [Manual Sync](/en/web/manual-sync) when a word itself starts or ends at the wrong time. Use **Fix line breaks** when the timing is already correct and only the grouping needs attention.
