Adjust captions to fit your scene

Speaking order

Keeps each sentence with its translation: original 1 → translation 1 → original 2 → translation 2.

Characters per line

Wrap after 1–120 characters. Set 0 for natural line wrapping.

Fit long captions

Reduce the text size when needed to fit the preview or OBS area.

Transparent caption background

Remove the caption box fill and border. A fine outline keeps the text readable.

Display duration

How long completed captions remain visible. The style sample stays visible while you edit.

Newest captions on top

Show the newest sentence above earlier captions.

Glossary entries

Enter a word to keep its spelling, or use source -> translation or source = translation to set a preferred translation. Separate up to 50 entries with line breaks or commas. Changes apply when the microphone connection starts or reconnects. The translation service can still vary the wording.

OBS overlay

Paste your own overlay URL from the workspace. Keep this link private. Set up captions in OBS
