Generation loss — quality may degrade
M4V 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 M4V file may contain MP4 atoms, iTunes tags metadata. MP3 has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
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.
