Drag any MP4 onto CallCove and get a clean text transcript in about a minute. Whisper large-v3-turbo runs on your Mac's Apple Neural Engine. No FFmpeg, no Python, no API keys, no uploads.
How it works with MP4 files
- 1
Drag the MP4 onto CallCove
From Finder, from a Slack download, from Drive — anywhere. .mp4, .mov, .mkv, .m4a, .mp3, .wav are all accepted.
- 2
Pick a language (or let it auto-detect)
Whisper auto-detects the spoken language. If you already know it, set it explicitly for slightly better accuracy on short or noisy clips.
- 3
Get a .txt next to your video
On an M-series Mac, a 60-minute MP4 transcribes in about 2 minutes. The .txt saves alongside the source file.
Why CallCove for MP4 files
Most online MP4 transcribers want you to upload the video — slow on big files, sketchy on private content, billed per minute. The local-Whisper route via terminal works but assumes a comfort with Python and FFmpeg most people don't have. CallCove is the menubar app that does both: extract the audio, run Whisper on the ANE, save a .txt next to the video.
- Drag-and-drop any common video format — MP4, MOV, MKV — and audio formats too
- Whisper large-v3-turbo running on the Apple Neural Engine, 15–30× real time
- Auto-detects the language from 99 supported languages
- Optional translate-to-English mode for foreign-language footage
- No FFmpeg install, no Python, no Hugging Face login, no API key
- Files never leave your Mac — runs offline
MP4 files — Q&A
How do I transcribe MP4 to text on Mac without uploading it?+
Drop the MP4 onto CallCove. The app extracts audio internally and runs Whisper large-v3-turbo on your Mac's Apple Neural Engine. Nothing is uploaded; the .txt transcript saves next to your MP4.
Can I transcribe video offline on Mac?+
Yes. The Whisper model ships with the app, runs entirely locally, and works on a plane. No internet connection is required at any step.
Is this just yt-dlp + whisper-cpp under the hood?+
Conceptually similar — Whisper-quality transcription on local hardware — but assembled, signed, and updated for you. If you're comfortable with the terminal route, it's free; if not, $15 saves you the install dance and gets you ANE acceleration tuned correctly.
Does it handle long videos?+
Yes. We've tested multi-hour MP4s. The bottleneck is your disk space for the audio extraction; transcription itself scales linearly.
Can it translate a foreign-language MP4 into English?+
Yes. Whisper has a built-in translate mode that outputs English regardless of source language. Set 'Translate to English' before starting.
Will it transcribe MOV, MKV, WAV, and MP3 too?+
Yes — anything FFmpeg recognizes. CallCove ships its own decoders, so you don't install FFmpeg separately.
