Generation loss — quality may degrade
M4V uses lossy compression, and so does JPG. 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. JPG 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
JPG lossy compression can produce blockiness and mosquito noise around sharp edges. 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.
