How this service works
Video to transcript: transcribe the speech in a video file at a URL (MP4, MOV, WebM, MKV with an audio track; max 20 MB) with Whisper large v3 turbo. Returns full text, language, duration, timestamped segments and WebVTT captions ready for subtitles. task=translate gives English text.
Output
A JSON object containing: the full transcript text, detected language code, audio duration in seconds, the model used (whisper-large-v3-turbo), video format, word count, an array of timestamped segments (each with start time, end time, and text), and implicitly WebVTT caption data ready for subtitle use.
Example use cases
Meeting recording to searchable notes
“I have a recording of our team meeting at https://storage.example.com/meeting.mp4 — can you transcribe everything that was said and give me timestamped segments so I can find who said what?”
Foreign-language video subtitles in English
“This product demo video at https://cdn.example.com/demo_es.mp4 is in Spanish — can you translate the speech to English and give me WebVTT captions I can use as subtitles?”
Podcast episode transcript for SEO
“Please transcribe the audio from this podcast episode at https://media.example.com/episode42.mp4 and return the full text and word count so I can publish it as a blog post.”
Technical details
Endpoint
GEThttps://agents.crowdspark.me/v1/video/transcribe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract speech from a video file (MP4, MOV, WebM, MKV) hosted at a public URL, especially when you also need timestamped segments and WebVTT captions in one call. Prefer it over audio-only transcription services when your source is a video file. Use the translate task when the source language is non-English and English output is needed. Best suited for files under 20 MB.
Side effects
- File exceeds 20 MB limit — returns error
- URL is not publicly accessible or returns 4xx/5xx — transcription fails
- Video has no audio track — returns empty transcript or error
- Unsupported file format (not MP4/MOV/WebM/MKV) — returns format error
- Network timeout fetching large video files
- Language detection fails for very short or noisy audio clips
