Generation loss — quality may degrade
OGV uses lossy compression, and so does VOB. 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 OGV file may contain Vorbis comments metadata. VOB 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
VOB lossy compression can produce MPEG-2 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 OGV file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with VOB-compatible codecs (typically H.264 for MP4)
