Generation loss — quality may degrade
MOV uses lossy compression, and so does MP3. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your MOV file may contain QuickTime atoms, chapter markers metadata. MP3 has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Default format on iPhone
Your device saves files in MOV by default (iPhone, iPad, Mac cameras). Most people convert because the files won't open on other devices — MP3 is universally supported and will work everywhere.
What compression artifacts to expect
MP3 lossy compression can produce pre-echo, swishing on transients, stereo imaging loss. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
