How SRT generation works
Why use Mictoo for SRT generation?
When SRT generation is useful
Tips for cleaner subtitles
- For files over 25 MB, sign in for auto-split uploads up to 180 MB.
- Set the language explicitly for non-English or technical content.
- Review names and unusual terms in Editor mode before export.
- Translate the transcript first, then export SRT for foreign captions.
What happens during generation
We transcribe your audio or video and return timestamped text for review and export.
Frequently asked questions
Is the SRT generator free?
Yes. Up to 25 MB anonymously or 180 MB when signed in. No watermark on the SRT and no per-minute fee.
Which subtitle formats do I get?
SRT and VTT are both included. TXT (plain text) and DOCX are also available. Signed-in users additionally get PDF and JSON.
How accurate are the timestamps?
Whisper large-v3 provides per-segment timestamps aligned to the original audio. Accurate enough for YouTube captions and most video editing use cases.
Do you identify speakers (diarisation)?
Not yet. Continuous captions with timestamps but no speaker labels. Diarisation is on the Pro roadmap.
Does Mictoo transcribe non-English audio?
Yes. Whisper large-v3 supports 50+ languages with auto-detection. Set the language explicitly for cleaner results.
Are recordings kept on your servers?
No. Audio streams to the transcription provider, gets processed once, and is dropped. Transcripts persist only on signed-in accounts.
