The Video Subtitle Generator turns recorded lessons and training videos into subtitled, transcribed content. Upload a video and TutorFlow produces timed subtitles and a full transcript, with no manual timing and no external transcription service.
What it accepts
| Input | Limits |
|---|---|
| Video file | MP4, MOV, WebM and other common formats, up to 1 hour long |
| SRT file | An existing subtitle file to edit, in the Edit SRT File mode |
Credits
Generating subtitles costs 1 credit per minute of video, so a 20-minute lecture costs 20 credits. The page shows the video length and the estimated credits before you confirm, and a confirmation dialog repeats the amount. Editing and downloading cost nothing, and editing an uploaded SRT file is free.
Typical workflow
- Upload the video. Recorded lectures, screen captures, training clips, and presentation recordings all work.
- Generate subtitles. Confirm the credit amount. TutorFlow transcribes the audio and times each line.
- Review and edit. Switch between the Edit, SRT, and Text tabs: fix a line in the editor, read the raw SRT, or copy the plain transcript.
- Download the SRT and attach it to the video in your player or LMS, or paste transcript text into course materials.
To fix subtitles you already have, choose Edit SRT File, upload the SRT alongside the video, and work in the same editor.
Why subtitles matter for learning content
Subtitles are not just an accessibility feature. They help:
- Non-native speakers who read along while listening
- Learners in noisy environments who cannot use audio
- Learners who prefer to read at their own pace
- Anyone reviewing content asynchronously who wants to search the transcript
For educators, a transcript also makes video content reusable. Paste sections into lesson summaries, quiz questions, or reference materials.
What to check in the review pass
AI transcription is accurate for most standard speech, but a review pass is always worthwhile before publishing. Pay attention to:
- Subject-specific terminology, proper nouns, and product names
- Passages where audio quality drops or speakers talk quickly
- Timing on edited videos, where a cut can shift a line
A review pass on a 20-minute lecture typically takes 5 to 10 minutes, far faster than transcribing by hand.
Common use cases
- Recorded lectures for asynchronous or flipped classroom delivery
- Corporate training videos that need to be accessible across regions
- Tutorial screen recordings for technical courses
- Language learning videos where subtitles play a direct instructional role
