Which languages can I transcribe?
English, Spanish, German, Romanian, French and Italian are supported out of the box.
Can I download the video with subtitles burned in?
Yes. You can hard-burn styled captions directly into the video, or export a separate soft SRT/VTT subtitle track — whichever fits your platform.
Do I need to install anything?
No. Caption Studio runs entirely in your browser. Upload, edit, and export without installing software.
