Captions are burned onto a finished clip from its own audio. ViralGen transcribes the speech into word level timestamps, previews them live over the video, and then burns styled, synchronized captions into the exported MP4.
Transcription first
The clip's audio is transcribed into word timed text before anything is burned in. If there is no speech in the audio, there is nothing to caption: the tool tells you rather than burning an empty track.
Style controls
You control the look: plain or highlight mode, position (top, middle, bottom), size (small, medium, large), colour (white, yellow, green, cyan and more), and optional all caps. A live preview shows the styled words over the original clip before you commit.
Burn, keep, or revert
Burning produces a new captioned clip you can preview in place. Keep it to make the captioned version the canonical clip, so it flows on through Audit, Schedule, and Drive, or revert to drop the edit and keep the original.
