Generation loss — quality may degrade
MPEG 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.
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 MPEG to VOB
Your MPEG 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 MPEG 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
