Format conversion
MOV to MP3
MOV is QuickTime's container — iPhone, Final Cut Pro, iMovie, and most macOS screen recorders. VideoSplit converts MOV to a 320 kbps MP3 client-side, so you skip the QuickTime Player export-audio-only flow and get the file directly.
MOV audio is typically AAC, sometimes PCM for Final Cut Pro exports. Both decode cleanly; PCM MOVs transcode especially cleanly because the source is already lossless.
Step-by-step
- Open VideoSplit.io. Drop your .mov file.
- Pick MP3. Click the MP3 tag in the waveform UI.
- Download. The MP3 saves with the MOV's original filename.
Quality and bitrate guidance
For phone MOV clips, the audio is usually 128 kbps AAC — the source is the bottleneck, and the 320 kbps MP3 output is as clean as that source allows. For PCM MOV exports from Final Cut, MP3 adds the only lossy step in the chain; if fidelity matters, go MP4-to-WAV instead.
Practical notes
- ProRes MOV files are very large — trimming in QuickTime first saves browser memory.
- For iPhone video clips, MP3 at 320 kbps is an excellent archival target for voice memos or interviews.
- Final Cut Pro exports sometimes have multi-channel audio; VideoSplit downmixes to stereo on export.
