Generation loss — quality may degrade
M2TS uses lossy compression, and so does OPUS. 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 M2TS file may contain Blu-ray metadata metadata. OPUS 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
OPUS lossy compression can produce minimal artifacts even at low bitrates. 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.
