Where to use your subtitle file

YouTube Studio

Upload the .srt file directly in YouTube Studio's subtitle manager — YouTube accepts SRT natively, no conversion needed.

Instagram & TikTok

Neither platform accepts SRT uploads directly, but most caption/editing apps for Reels and TikTok let you import an SRT and burn the captions into the video.

VLC and other media players

Drop the .srt file in the same folder as your video with a matching filename, or load it manually — most players pick it up automatically.

Video editors

Premiere Pro, DaVinci Resolve, CapCut and most editors can import SRT or VTT as a caption track you can style and position.

SRT or VTT — which do you need?

SRT (SubRip)

The most widely supported subtitle format — plain text timestamps and captions. Use this if you're not sure which one you need.

VTT (WebVTT)

The web standard, used by HTML5 <track> elements and some platforms that specifically ask for it. Functionally similar to SRT with minor formatting differences.

Frequently Asked Questions

Subtitle-specific questions about SRT and VTT exports

What's the actual difference between SRT and VTT?
Both store the same thing — timestamped caption text — in slightly different formats. SRT uses a comma for the timestamp's millisecond separator and is the more universally recognized format; VTT uses a period and is the format HTML5 video players expect natively. Export whichever your destination platform asks for — SRT if you're not sure.
How are the subtitles timed?
Each cue is generated from the AI transcript's own timestamps, split at natural sentence or comma boundaries, with a maximum of 42 characters per line and 2 lines per cue — the same limits most professional subtitle guidelines use — and each cue lasts between 1 and 7 seconds.
Can I fix the subtitle text before exporting?
Yes. The transcript is fully editable before you export — fix any misheard words or names directly in the editor, and the correction carries through to both the SRT and VTT exports.
Does YouTube accept SRT files?
Yes, directly — YouTube Studio's subtitle upload accepts .srt files with no conversion step.
Is there a limit on how long my audio or video can be?
No. Transcribe a 5-minute clip or a 2-hour recording — there's no artificial length cap, just what your device can handle.
