Generation loss — quality may degrade
OGV uses lossy compression, and so does MP4. 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. MP4 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
MP4 lossy compression can produce blockiness, banding in gradients, mosquito noise. 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 OGV to MP4
Your OGV video is transcoded — video and audio streams are decoded and re-encoded into the MP4 container. This is a lossy process that takes time proportional to the video duration.
Your OGV file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with MP4-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 MP4 container and the file is saved
