Yes. Medeo supports full subtitle styling, including:
Font family
Font size
Bold
Text color
Stroke / outline
Preset animations
You can access these options from the subtitle toolbar on the timeline. Subtitles are auto‑generated from your voiceover or script, and you can edit both the text and the styling at any time. What you see in preview matches the final export exactly. Subtitles are added directly in the video editor.
