Follow the voice

videoFn transcribes speech on your Mac. Captions use the word timings to appear with the voice and stay in sync with the edit.

Make room for the words

The agent can choose a caption style and checks contrast, wrapping and overlap. It uses those findings to correct text that is hard to read.

Keep the meaning right

Check names and wording in the preview. Use your script to correct misheard words through chat, or change the text in the editor.
