Generation loss — quality may degrade
OGG uses lossy compression, and so does MKV. 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 OGG file may contain Vorbis comments metadata. MKV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
