Generation loss — quality may degrade
MP4 uses lossy compression, and so does OGG. 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 MP4 file may contain MP4 atoms, chapter markers metadata. OGG 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
OGG lossy compression can produce warbling at very low bitrates. 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 MP4 to OGG
The audio track is extracted from your MP4 video file and saved as OGG. The video frames are discarded.
Your MP4 file is opened and the container is parsed to identify audio and video streams
The audio stream is extracted — if it's already in the target codec, it's copied directly (no quality loss)
If transcoding is needed, the audio is decoded and re-encoded as OGG
Video frames, subtitles, and chapter markers are discarded
The OGG file is saved with preserved metadata (title, artist, etc.) where possible
