Video Transcripts

Subtitles are no longer optional -- they are essential for accessibility compliance, social media engagement, and global reach. The majority of social media video is watched with sound off, making subtitles critical for getting your message across. For accessibility, captions are a legal requirement in many contexts and make your content available to the deaf and hard-of-hearing community.

Auto-generated subtitles from platforms like YouTube are often riddled with errors -- especially for technical content, brand names, and non-native speakers. Extracting the transcript and using it as the basis for accurate subtitle files gives you control over the quality of your captions.

The extracted transcript with timestamps can be reformatted into standard subtitle formats (SRT, VTT) for use across any video platform. You can also edit the transcript for accuracy before generating subtitles, ensuring your viewers see clean, correct captions rather than the garbled auto-generated alternatives.
