Questions
Is my video uploaded?
No. Whisper runs in your browser, so the audio is transcribed on your device. Only the model downloads once and is cached.
SRT or VTT?
SRT works almost everywhere (YouTube, Premiere, VLC). VTT is the web standard used by the HTML <track> element.
How do I adjust timing?
Edit the start and end times of any caption, click a caption to jump the player there, or use “Set start/end to now” while the media plays.
