The Subtitle Format Converter You’ve Been Looking For [FREE TOOL]
Updated: February 7, 2024
Video is everywhere today — on mobile, on the web, on social media — and everywhere your video is published, its subtitles should work.
But sometimes it seems like every app or device requires a different subtitle format. YouTube accepts caption files in a different format than QuickTime videos; Flash videos take DFXP while Windows Media Player videos accept SMI. There’s a dizzying amount of different subtitle formats, and it can be tough to know which ones you need.
To make matters worse, it’s surprisingly difficult to convert subtitle files from one format to another.
Subtitle Converter Tool
To tackle the problem of converting subtitle formats, 3Play Media created a free tool that lets you convert your subtitles online.
Our subtitle format converter tool converts SRT (SubRip subtitle) or SBV (YouTube) to any of the following formats:
- CPT.XML (Flash Captionate XML) – For encoding Flash videos
- DFXP – More commonly used for Flash videos
- QT (Quick Text) – for QuickTime videos
- SCC (Scenarist Closed Caption) – Popular for Line 21 broadcast closed captions, web media, & DVDs, as well as iTunes video (input file must have 32 characters or less per line)
- SMI or SAMI – For Windows Media Player
- SRT (SubRip Subtitle) – The most common subtitle format
- STL (Spruce Subtitle File) – Used for DVD Studio Pro
- WebVTT – Used for HTML5 video
How to Convert Subtitles for iPhone
iOS devices are not very caption-friendly. The easiest way to publish captioned videos that play on iPhones, iPods, or iPads is to encode captions directly within the file. This process is called caption encoding.
