How do I add subtitles to a video automatically?

Upload your video and Melies uses AI speech recognition to transcribe the audio into timed captions automatically. Edit any wording, choose a style, then burn the subtitles in or export an SRT file.

Is the subtitle generator free?

Generation requires credits from a paid plan. Generating subtitles uses credits based on the video length. Paid plans include more credits.

Can I export an SRT file?

Yes. You can download captions as SRT or VTT files, or burn them directly into the video. SRT works with YouTube, Vimeo, and every major editor.

How accurate are the AI subtitles?

The AI uses modern speech recognition for high accuracy across accents and clear audio. You can review and edit any line before exporting, so the final captions are exactly right.

Can I translate the subtitles into another language?

Yes. After generating captions you can translate them into 30+ languages in one click, then export or burn in the translated version.

Can I style the subtitles?

Yes. Choose the font, size, color, and position. Pick clean broadcast captions or bold karaoke-style subtitles popular on social media.

Will captions stay in sync with the video?

Yes. Each caption is timestamped to the frame during transcription, so subtitles stay perfectly aligned with the speech.

Can I caption videos for TikTok, Reels, and Shorts?

Yes. Use burn-in mode so captions are baked into the video and always visible, which is ideal for muted autoplay on social platforms.
