Training Video Captions — WCAG-Ready SRT in Minutes
Upload any training, onboarding, software tutorial, or compliance video. Musely generates accessible SRT captions at 97.3% accuracy — product names preserved, reading speed tuned for learners, WCAG AAA features on demand.
Musely Training Video Caption Generator is a purpose-built subtitle tool for corporate L&D, instructional designers, and e-learning creators. It transcribes training videos with Seed-ASR 2.0 at 97.3% accuracy across 51 languages, then generates SRT or VTT captions optimized specifically for learning contexts — slower reading speeds for non-native speakers, preserved technical vocabulary for software training, and full WCAG AAA accessibility features on demand (speaker identification, sound descriptions, on-screen text capture). Choose from 4 presets: Corporate / Onboarding, Software / Technical Training, E-Learning Course, or Compliance / Regulatory. Supports videos up to 4 hours long and exports to every major LMS.

Generate Training Captions in 3 Steps
Upload Your Training Video
Drag and drop your MP4, MOV, WebM, or any video export from Camtasia, Articulate Storyline, Adobe Captivate, or Vyond. Musely accepts videos up to 4 hours long — long enough for full course modules and multi-part training series.
Pick a Training Preset and Configure Accessibility
Choose Corporate / Onboarding for HR and policy videos, Software for product tutorials, E-Learning for LMS courses, or Compliance for audit-ready regulatory training. Set line length (32-60 chars), reading level (ESL-friendly to Technical), and turn on WCAG AAA features: speaker identification, sound descriptions for alerts and alarms, and on-screen text capture for slide-heavy content.
Download SRT and Upload to Your LMS
Review the generated captions with product names and technical terms preserved. Download as SRT (universal), VTT (HTML5 / modern LMS), TXT, or DOCX. Upload directly to Canvas, Moodle, Blackboard, Teachable, YouTube, Vimeo, or Panopto — or import into Camtasia / Premiere for caption burn-in.
Who Uses Musely Training Video Captions
Caption new-hire onboarding videos for accessibility compliance
We onboard 200 new hires per quarter and every training video needs captions for ADA compliance. Musely's Corporate preset delivers WCAG-ready SRT in 5 minutes. Our internal acronyms get added to custom vocabulary once and show up correctly across all 40 videos in the onboarding path.
Caption e-learning courses for global student populations
I build courses for a university with 30% ESL students. The Simplified reading level preset produces captions my students can actually follow — shorter lines, slower pace. I toggle on sound descriptions for our branched scenarios where audio cues matter. Course completion rates went up 12%.
Caption product tutorial videos with accurate technical vocabulary
Our product has 400+ features with specific brand names. Musely's Software preset preserves every one — 'Composable Layouts', 'AI Draftsmith', our API endpoint names all spelled correctly. The custom vocabulary field handled our entire product glossary in one paste. Customer support tickets asking 'how is X spelled' dropped to zero.
Produce audit-ready captions for regulatory training
Our compliance training gets audited by regulators. The Compliance preset produces strict verbatim captions with speaker IDs — exactly what our audit package requires. I stopped sending videos out for third-party captioning at $6/minute. Saves us roughly $40K/year.
Localize English training content for international offices
We have offices in Germany, Japan, Brazil, and Mexico. I upload each English training video once, then generate Spanish, German, Japanese, and Portuguese SRT files. Bilingual mode works for our bilingual teams who want both languages in the caption track. One tool replaced 4 localization vendors.
Caption short-form training for mobile learners
We ship 2-5 minute micro-learning clips to sales reps on mobile. The 32-character line length and 1-line-per-entry option deliver mobile-optimized captions with no horizontal scrolling. Our reps actually watch our content now — engagement on mobile doubled once we fixed the caption formatting.

What L&D Teams Say
4.8/5 based on 2,610 reviews
“We retired our $40K/year human captioning vendor after 3 months on Musely. The Compliance preset produces verbatim captions with speaker IDs that pass our internal audit review. Our regulatory training library of 120 videos was re-captioned in a week instead of the usual 2-month turnaround.”
“The Software Training preset is built for people like me. Product names, feature names, CLI commands — all preserved exactly. The custom vocabulary field took our entire product glossary. I don't have to manually find-and-replace anymore. Captions upload straight to Teachable and Wistia.”
“Finally a captioner that understands L&D audiences need slower reading speeds. The 14-18 char/sec pace is genuinely easier for our global workforce than the standard 20+ char/sec. Occasional tweaks needed for our industry jargon but custom vocabulary covers most of it.”
