Why Is My Recording an M4A File?
M4A is the default output of Apple's Voice Memos app and many Android and desktop recording tools — it's a compressed format that keeps decent audio quality at a much smaller file size than WAV, which is why phone manufacturers default to it. If you recorded a voice memo, an interview, or a quick note on your phone, there's a good chance it's already M4A.
How to Convert an M4A File to Video
- Upload the M4A file directly — no need to convert it to MP3 first.
- Transcription runs automatically, producing sentence-level timestamps.
- Stock footage is matched to each sentence from a licensed library.
- Clips are trimmed and assembled in order, synced to your original audio.
- Captions are burned in and the video exports as an HD MP4.
