FAQ
What is a VTT (WebVTT) file?
WebVTT (Web Video Text Tracks) is the W3C standard for caption files used in HTML5 video. VTT files start with "WEBVTT" and use timestamps in HH:MM:SS.mmm format. Unlike SRT, VTT supports CSS styling cues and cue positioning.
Is the VTT generator free?
Yes. VTT export is free on all plans, including the free tier. No watermark is added to VTT files.
What is the difference between SRT and VTT?
SRT is more widely supported by legacy tools and desktop players. VTT is the modern web standard for HTML5 <track> elements and supports styling. CutSnap exports both from the same caption source.
Can I use the VTT file with the HTML5 <track> element?
Yes. CutSnap VTT files are standards-compliant and work directly with <track kind="subtitles" src="captions.vtt" srclang="en">.
Do CutSnap VTT files include cue styling?
Currently CutSnap VTT exports contain timing and text. CSS cue styling is on the roadmap. For burned-in custom styles, export the MP4 instead.
What languages are supported?
CutSnap supports 90+ languages for AI transcription, including Arabic, Hebrew, Urdu, Japanese, Chinese, and all major European languages.
