• Automatic Transcription: Upload your video, audio, or SRT file, and our AI will transcribe the speech in 100 languages, accurately timing each word to the audio.
• Customizable Styles: Choose from over 22 caption styles, including word animation, karaoke, and highlight effects. Personalize fonts and colors to match your brand.
• Multi-Language Support: Supports transcription in 100 languages with automatic detection. Translate subtitles into over 100 languages for free, or display bilingual captions.
• Flexible Export Options: Download your captioned video as an MP4 file (up to 4K with Pro) or as subtitle files in SRT, VTT, and TXT formats.
