SRT (SubRip) is the most widely supported subtitle format in the world. Created in the early 2000s by the SubRip DVD ripping program, the format uses a simple, human-readable structure that has become the universal standard for video captioning. Every major video player — VLC, MPC-HC, PotPlayer, Windows Media Player — supports SRT files natively. All streaming platforms including YouTube, Vimeo, Netflix, and Kaltura accept SRT uploads. Professional video editing software like Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro can import and export SRT files. The format's simplicity is its greatest strength: plain text with no styling means guaranteed compatibility across all platforms, devices, and operating systems. SRT files use the timestamp format HH:MM:SS,mmm with commas separating milliseconds, and entries are separated by blank lines. Each entry consists of a sequence number, a timestamp range, and one or more lines of caption text.
