To create a subtitle track, upload your video to the Flixier dashboard and use the auto-subtitle feature to generate text from your audio. Once the transcription is complete, you can review the timing and then export the file specifically in the VTT format.
What is a VTT file used for?
A VTT file is a standard subtitle format used for displaying timed text on web-based video players. It is the primary format for HTML5 video and is widely supported by streaming platforms to provide accessibility and captions for viewers across the globe.
Can I generate VTT files from MP4 automatically?
Yes. You can create VTT file assets from MP4 recordings automatically using our AI-powered transcription engine. The system identifies the speech in your video and creates a synchronized subtitle track that you can download and use instantly.
How do I add VTT captions to HTML5 video?
Once you have generated and downloaded your VTT file from Flixier, you can link it to your HTML5 video using the "track" tag within your website's code. This allows browsers to automatically display the subtitles when a user watches your video.
Is the VTT generator free?
