SRT vs VTT: choose the subtitle file your destination expects
SRT is a simple, widely accepted subtitle format. WebVTT is designed for web video and supports browser-oriented features that SRT does not represent.
Export SRT when a video editor or upload form asks for SRT or when broad subtitle compatibility is the priority. Export VTT for HTML video and web players that expect WebVTT. Always review the text and timing in the destination player.

Which subtitle format should you choose?
A video editor requests SRT
Export SRT and import it directly, then check line breaks and timing on the edit timeline.
An HTML video player uses a track element
Export VTT and set the track source to the WebVTT file.
The platform accepts both
Prefer the simpler format already used by the rest of the publishing workflow.
What should you check after export?
Automatic transcript segments are a starting point. Check spelling, reading speed, line length, timing and sound context in the final video.
Converting between formats can preserve basic text and timing, but VTT-specific cue settings do not have a direct SRT equivalent.
Questions about this guide
Is VTT more accurate than SRT?
No. The format does not change speech-recognition accuracy. It changes how timed text and cue settings are represented.
Can I open SRT and VTT files in a text editor?
Yes. Both are text-based formats, so you can inspect and edit them directly.
Which format should I upload to YouTube?
Use a subtitle format accepted by the current YouTube upload flow and check the imported captions. SRT is a common choice, but platform support can change.
