How to Organize Subtitle Files for Corporate Training

Training libraries grow quickly. A simple, consistent structure saves time every time a module is updated or moved to a new platform.

Name files after the video

Use the video's file name with the language code and extension:

onboarding-01-welcome.mp4
onboarding-01-welcome.en.srt
onboarding-01-welcome.en.vtt

Many players and LMS tools match subtitles to video by name, and the language code makes multilingual libraries unambiguous later.

Mirror the course structure

/training
  /onboarding
    onboarding-01-welcome.en.srt
    onboarding-02-tools.en.srt
  /compliance-2026
    compliance-01-overview.en.srt

Avoid spaces and special characters

Use lowercase letters, digits and hyphens. Some systems mishandle spaces, accents and punctuation in file names.

Keep a manifest

A spreadsheet listing each video, its duration, subtitle files, last update and status makes audits and updates far easier.

Video	Duration	Subtitles	Updated	Status
onboarding-01-welcome	06:12	en.srt, en.vtt	2026-09-14	Validated

Version re-edited modules

When a module is re-recorded, update the subtitle file at the same time and record the date in the manifest. Out-of-date subtitles on an updated video are a common source of complaints.
