MP4 to Text
MP4 is the format most recordings end up in — screen captures, phone videos, downloaded meetings. ClapClip converts MP4 files straight to text on your Windows PC: the audio track is extracted automatically and transcribed locally with Whisper-grade accuracy.
- Transcribe MP4 directly, no audio extraction
- Any audio codec inside the MP4 container
- No file size or length limits
- Local processing — large files never uploaded
Windows 10 & 11
Direct MP4 input, no conversion step
ClapClip decodes the MP4 container directly, whatever audio codec is inside — AAC, MP3, or others. You drop the file in and get text out; there is no intermediate export to WAV or MP3.
Large MP4 files stay on your disk
A one-hour 1080p MP4 can be several gigabytes. Uploading that to a cloud transcriber takes longer than transcribing it locally. ClapClip reads the file from disk, so file size only affects decode time, not an upload queue.
From screen recording to documentation
Tutorials, demos, and recorded calls captured as MP4 become searchable text: meeting minutes, how-to docs, or subtitles for accessibility — all from the same transcription pass.
FAQ
Do I need to extract audio from the MP4 first?
No. ClapClip reads MP4 files directly and extracts the audio track internally before transcribing.
Is there a file size limit?
No. Because nothing is uploaded, even multi-gigabyte MP4 files are fine — they are read directly from your disk.
Can I export subtitles for my MP4?
Yes. ClapClip can output timestamped subtitles alongside plain text.
Does the audio codec inside the MP4 matter?
No. ClapClip decodes the audio track regardless of whether it's AAC, MP3, or another codec the container carries.
