Generation loss — quality may degrade
WMV uses lossy compression, and so does OGG. 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 WMV file may contain ASF metadata, DRM tags metadata. OGG 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
OGG lossy compression can produce warbling at very 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.
