If Opus is lossless (WAV, FLAC), every sample is preserved exactly. If Opus is lossy (MP3, AAC, OGG, Opus), the Opus codec recompresses — at 192 kbps this is transparent for almost all content. Recovering quality that was already gone in the MP4 source is impossible.

If the MP4 container has chapter or stream metadata, we copy artist / title / album fields into the Opus container where the Opus format supports tags. Otherwise the Opus file is untagged — use a tag editor (Mp3tag, Picard) post-export for richer tags.

Channel layout is preserved from MP4 by default — a 5.1 MP4 produces a 5.1 Opus where the codec supports it (AAC, FLAC, OGG, Opus). You can force stereo or mono via the channel-downmix option, which is useful for podcast workflow.
