Generation loss — quality may degrade
DIVX 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.
What compression artifacts to expect
MKV lossy compression can produce codec-dependent. 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 DIVX to MKV
Your DIVX video is transcoded — video and audio streams are decoded and re-encoded into the MKV container. This is a lossy process that takes time proportional to the video duration.
Your DIVX file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with MKV-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 MKV container and the file is saved
