Generation loss — quality may degrade
M4V uses lossy compression, and so does M4A. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
What compression artifacts to expect
M4A lossy compression can produce pre-echo at low bitrates (AAC). 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.
