Generation loss — quality may degrade
VOB uses lossy compression, and so does M2TS. 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 VOB file may contain DVD IFO data metadata. M2TS 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
M2TS lossy compression can produce H.264/MPEG-4 AVC artifacts. 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.
