Generation loss — quality may degrade
WMV uses lossy compression, and so does MOV. 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. MOV 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
MOV lossy compression can produce codec-dependent (ProRes: minimal, H.264: blockiness). 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.

Your WMV file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with MOV-compatible codecs (typically H.264 for MP4)

Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the MOV container and the file is saved
