The short answer
Drag any MP4, MOV, WEBM, MKV, or AVI into VexaScribe and get both a timestamped transcript AND SRT subtitles in ~10 minutes per hour of video. Up to 5 GB per file (most free tools cap at 25 MB), 99 languages, speaker labels included. Free for the first 30 minutes, then $2–$20/month for higher volume.
Edge cases where another option fits: for HR investigations or legal video with sensitive employee data, install OpenAI Whisper locally. For YouTube URLs, use our YouTube transcription tool instead (direct URL input). For everything else, VexaScribe is the fastest path.
Transcript or Subtitle? (Pick the Right Output)
These are different outputs from the same processed video, used for different jobs. You don't need to choose one — VexaScribe exports both from a single upload. But knowing which one you need tells you what to do with the file after.
📄 Transcript (TXT or DOCX)
Use for: reading material.
- Repurposing a video into a blog post
- Show notes for podcast videos
- Research analysis (focus groups, qualitative video)
- Email newsletter from a webinar
- Internal documentation from training videos
🎬 Subtitle file (SRT or VTT)
Use for: on-screen captions.
- YouTube subtitle upload
- TikTok / Reels / Shorts captions (drives 80% sound-off engagement)
- Accessibility compliance (WCAG 2.1)
- Import into Premiere Pro, Final Cut, DaVinci Resolve
- Multi-language captions for international audiences
Both formats use the same timestamps under the hood — VexaScribe just exports them in different file layouts. SRT has chunk numbering and time codes; TXT/DOCX has inline timestamps.
Supported Video Formats (What Actually Works)
You don't need to convert your video or extract audio first. VexaScribe accepts all common container formats and codecs directly. If your file plays in VLC or QuickTime, it'll work here.
| Format | Where it comes from | Works? |
|---|---|---|
| MP4 (H.264 / H.265) | YouTube exports, smartphone recordings, screen capture, most editors | ✓ Yes — most common |
| MOV (QuickTime) | iPhone recordings, Mac screen recordings, GoPro, ScreenFlow | ✓ Yes |
| WEBM | YouTube downloads, Loom, browser-based recorders, OBS | ✓ Yes |
| MKV (Matroska) | High-quality video archives, multi-track content | ✓ Yes |
| AVI | Older Windows recordings, legacy footage | ✓ Yes |
| WMV (Windows Media) | Older Windows screen recorders, PowerPoint exports | ✓ Yes (consider MP4 for future-proofing) |
| ProRes RAW / DNxHR / R3D | Cinema camera RAW workflows | ✗ Not directly — export to MP4 first from your editor |
Quick test: if your file plays in VLC or QuickTime, VexaScribe will process it.
How VexaScribe Compares to Other Video-to-Text Tools
A few tools compete in this space. Here's how VexaScribe stacks up against the most-searched alternatives, with honest trade-offs where another option may fit your specific case better.
| Tool | File size cap | Languages | Pricing | Best for |
|---|---|---|---|---|
| VexaScribe | 5 GB | 99 | 30 min free $2–$20/mo | Long-form video, multi-language, both transcript + SRT in one upload |
| VEED | ~250 MB (free) 1 GB+ (paid) | 125 (claimed) | Free tier $12–$30/mo | Creators who want video editing in same tool. Claims “99.9% accuracy” — marketing number; real WER is 3–8%. |
| Descript | ~512 MB on starter | 23 | $15–$30/mo (no free tier) | Podcast editors using Descript's editor workflow. Limited language support. |
| Otter.ai | ~300 MB on free Higher on paid | 3 (en/es/fr) | Free (300 min) $8.33+/mo | Live meeting recording with calendar integration. Limited language support for international video. |
| OpenAI Whisper (local install) | Unlimited | 99 | $0 forever | Sensitive video (legal, HR, clinical). Requires Python setup; slower on CPU than cloud tools. |
| Free converter sites | ~25 MB | Varies | $0 | Avoid for serious work. Most use pre-2020 speech engines with much lower accuracy. |
Numbers above reflect each vendor's published limits and pricing as of June 2026. We're biased (we built VexaScribe), but the comparison data is accurate per public sources.
Common Use Cases for Video Transcription
🎬 Content creators
TikTok / Reels / YouTube Shorts subtitles for sound-off viewing. Repurpose long-form podcast video into blog posts, email newsletters, Twitter threads. Pull quote graphics from interview segments.
🎓 Students & academics
Lecture recordings, recorded Zoom classes, qualitative research video (interviews, focus groups). Searchable text for study prep and citation.
📈 Marketers
Webinar → blog post / email / social clips. Conference talk → SEO content. Customer testimonial video → quote library. Long-form sales pitch → searchable knowledge base.
📰 Journalists
Video interview footage → searchable transcripts for article writing. Recorded press conferences → quote extraction. Fast turnaround for breaking news from on-camera sources.
🏢 L&D / HR teams
Training video library → searchable transcripts (find “harassment policy” in 200 hours of onboarding content). All-hands recordings → meeting minutes. Accessibility compliance via captions.
🔬 Researchers
Focus group videos, ethnographic recordings, video diaries. Speaker labels enable participant-by-participant analysis. Time-stamped quotes for direct citation in papers.
The File Size Reality — Videos Are Big
Video files are 10–30× larger than audio files of the same length. That's the single biggest reason most free transcription tools fail on video. Realistic sizes at common quality levels:
| Video length | 720p file size | 1080p file size | Tools that handle 1080p |
|---|---|---|---|
| 10 minutes | ~80 MB | ~150 MB | VexaScribe, Descript paid, AssemblyAI |
| 30 minutes | ~250 MB | ~500 MB | VexaScribe, AssemblyAI API, Whisper local |
| 1 hour (typical webinar) | ~500 MB | ~1 GB | VexaScribe (5 GB cap), Whisper local (unlimited) |
| 2 hour (conference talk) | ~1 GB | ~2–3 GB | VexaScribe (under 5 GB), Whisper local |
Three practical workarounds when you hit a limit:
- Use a tool with a higher cap — VexaScribe accepts up to 5 GB.
- Compress to 720p with Handbrake (free). Audio quality is what matters for transcription, not visual resolution.
- Split with ffmpeg into chunks, transcribe each, then concatenate the text.
Got a large video? Skip the compression workflow.
Upload Up to 5 GB — Try VexaScribe FreePrivacy — VexaScribe's Approach + When Local Install Is Right Instead
How VexaScribe handles your video
- We don't train models on customer video or transcripts.
- You can delete any file at any time from the dashboard — video and transcript both removed.
- Files are encrypted in transit (TLS) and at rest.
- Avoid unknown free “converter” sites with no privacy policy — that's the highest-risk option for any non-public content.
For most business video — webinars, all-hands, training recordings, marketing content, customer videos — VexaScribe is the right choice. Our data practices cover what teams typically need.
One honest exception: if your video contains HR investigations with employee PII, attorney-client privileged content, clinical or therapy recordings, or executive-only strategic discussions where a leak would create legal liability — install OpenAI Whisper locally so the file never leaves your computer. The local-install option exists exactly for this case. It's slower and requires Python setup, but the privacy guarantee is absolute.
For sensitive content, always verify each vendor's data policy directly on their site before uploading. Treat “free” tools with no published policy as if your video will be retained indefinitely.
