How to Transcribe Video to Text Online (Any Format, Any Language)

Why Transcribing Video Matters

Video content is rich but inaccessible. Search engines cannot index spoken words. Viewers with hearing impairments cannot follow along without captions. Content creators cannot repurpose video into blog posts or training materials without a transcript. Video transcription solves all three problems in one step: it makes spoken content searchable, accessible, and reusable.

Frequently Asked Questions

Can I transcribe a video with multiple languages?

Yes. Enable auto language detection when uploading. The engine detects the dominant language and transcribes accordingly. For videos that switch languages mid-recording, contact support for a multi-language pass option.

What is the difference between SRT and VTT output?

Both formats contain the same transcript content with timestamps. SRT (SubRip) is the standard for most video platforms (YouTube, Vimeo, social media). VTT (WebVTT) is the web standard used in HTML5 video players and modern browsers. If unsure, choose SRT — it is accepted everywhere.

Does transcribing a video also generate captions?

Yes. The SRT and VTT export files are ready-to-upload caption files. On YouTube, go to Videos > Subtitles > Add subtitles > Upload file and upload the SRT directly. The captions are synchronized to your video automatically.

Is there a file size limit?

For longer or larger videos, split the video into segments or upload the audio track only (which is much smaller) for faster processing.
