Download your transcript or captions
Once transcription is complete, download a plain text file for editing, an SRT or VTT subtitle file for video players and editors, or an MP4 with captions burned directly into the video if you uploaded one. All output formats are available from the same results screen.
Why choose CentClip?
Works with every M4A source Apple produces
M4A is the default recording format for iPhone Voice Memos, QuickTime screen recordings, and GarageBand exports - which means a lot of raw audio sits in M4A format and never gets transcribed. CentClip handles M4A natively without any conversion step. Drop the file straight from your Downloads folder or AirDrop and you're done. No re-encoding, no format errors.
Pay only for what you transcribe - no monthly seat fee
Most transcription tools charge a monthly subscription whether you use them or not. CentClip runs on a credit model at 5 cents per minute, so a 30-minute interview costs $1.50 and a 90-minute podcast episode costs $4.50. Your first 5 minutes are free with no account needed. Credits you buy never expire, so there's no pressure to burn through them before a billing cycle resets.
Get clean output you can actually use downstream
Raw transcripts are only useful if they slot into your existing workflow. CentClip exports SRT and VTT files that import directly into Premiere Pro, DaVinci Resolve, YouTube Studio, and most podcast platforms - no reformatting required. The plain-text transcript includes timestamps so you can scan to any moment quickly. If you need captions on a video file, burned-in MP4 export is a single click from the same screen.
FAQ
How accurate is M4A transcription?
Accuracy depends on audio clarity, but clean M4A recordings from a phone or USB microphone typically come back at 95% or better. Background noise, heavy accents, or multiple overlapping speakers will reduce accuracy.
Is there a free trial, and what does it cost after that?
Your first 5 minutes are free with no account or credit card required. After that, transcription costs 5 cents per minute - you buy credits in whatever amount you need and they never expire.
Can I transcribe M4A files recorded in languages other than English?
Yes - CentClip supports 50+ languages including Spanish, French, German, Portuguese, Japanese, Korean, and many more. Select the spoken language before submitting and the transcript will be returned in that language.
Do purchased credits expire if I don't use them right away?
Credits never expire. Buy a block when you have a batch of recordings to process and come back whenever your next project lands - your balance will still be there.
