SRT vs VTT
Both formats represent timed text. The right choice depends on where the subtitles will play.
SRT (SubRip)
- Plain, simple, and widely supported in desktop editors and many social platforms.
- Minimal metadata - great when you just need words and timings.
- Weak at advanced styling inside the same file (no standard bold per-line rules in basic SRT).
VTT (WebVTT)
- Designed for the web; pairs well with HTML5 video.
- Supports cues, styling hooks, and richer timing options in many pipelines.
- Slightly more complex than SRT for simple "export and upload" flows.
Practical rule
If your platform asks for SRT, use SRT. If your platform asks for VTT or WebVTT, use VTT. If you only have SRT and need VTT, many tools can convert between them - the hard part is timing and text quality, not the wrapper format.
