Generation loss — quality may degrade
AVI 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 AVI file may contain RIFF chunks 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.

What Happens When You Convert AVI to VOB
Your AVI video is transcoded — video and audio streams are decoded and re-encoded into the VOB container. This is a lossy process that takes time proportional to the video duration.
Your AVI 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)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the VOB container and the file is saved
