The Complete Guide to Subtitle Formats
Choosing the right subtitle format depends on where your video will be published. SRT is the safe default — it works on YouTube, in every video editor, and in virtually every media player. If you only download one format, make it SRT.
VTT is the modern web standard. If you're embedding video on a website using HTML5, VTT gives you the ability to style captions with CSS — change fonts, colors, and positions. It's also the native format for Vimeo and many e-learning platforms.
ASS is the power user's format. It supports multiple subtitle tracks, advanced positioning, custom fonts, and even animation effects. It's the standard in anime subtitling and professional post-production where subtitles need to match a specific visual style. TXT is simply the raw transcript without timestamps — perfect for blog posts, show notes, SEO content, and further text processing.
Frequently Asked Questions About Subtitle Generation
What is the difference between SRT and VTT subtitle formats?
SRT (SubRip) is the most widely supported format — it works with YouTube, VLC, Premiere Pro, and virtually every video player. VTT (WebVTT) is the web standard designed for HTML5 video, with support for styling and positioning. Both contain timestamps and text, but VTT offers more formatting options for web playback. Transcrify generates both automatically.
Can I edit subtitles after generating them?
Yes. Transcrify includes a built-in subtitle editor where you can adjust timing, edit text, split or merge segments, and preview changes — all in your browser. No external software like Aegisub or Subtitle Edit needed.
How do I burn subtitles into my video?
There are two types of subtitles: soft subs (separate SRT/VTT files that viewers can toggle on/off) and hard subs (burned permanently into the video). Transcrify generates soft subtitle files. To burn them in, import the SRT file into your video editor (Premiere Pro, DaVinci Resolve, Final Cut) or use free tools like HandBrake or FFmpeg.
What is an ASS subtitle file?
ASS (Advanced SubStation Alpha) is an advanced subtitle format that supports custom fonts, colors, positions, animations, and karaoke effects. It is popular in anime fansubbing and professional subtitling where styled captions are needed. Transcrify generates ASS files with clean default styling that you can customize.
Can I translate subtitles to another language?
Yes. After generating subtitles, you can translate them into 50+ languages using Transcrify's caption translation feature. The translated subtitles maintain the original timing, so they stay perfectly synced with your video.
