How to transcribe hls4ml recordings

hls4ml makes the recording — Whipscribe makes it text. Three steps, and the first preview is free with no signup.

The three steps

Get the audio out. Save the VOD or recording from hls4ml and upload it — long files are expected.

Drop it below. Upload the file right here — no signup for the instant preview. Long, multi-hour files are fine, and video uploads work too (we transcribe the audio track).

Take the text with you. Accurate, speaker-labeled text with timestamps — export TXT, SRT, VTT or DOCX, in 100+ languages, processed on Whipscribe's own private cloud.

Frequently asked

Can Whipscribe transcribe streams and VODs from hls4ml?

Yes — any audio or video file hls4ml produces can be uploaded directly. Save the VOD or recording from hls4ml and upload it — long files are expected.

Do I need to convert the file first?

No. Common audio and video formats upload as-is; video's audio track is transcribed automatically.

How accurate is it?

Clear speech in major languages comes back near-publishable; noisy or heavily accented audio deserves a review pass. The instant preview shows real output before you commit.

What does it cost?

About $2 per audio hour as pay-as-you-go credits that never expire — the first preview is free with no signup.
