Generation loss — quality may degrade

M4V 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 M4V file may contain MP4 atoms, iTunes tags metadata. MKV 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

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.

1

Your M4V file is demuxed — video, audio, and subtitle streams are separated

2

The video stream is decoded frame-by-frame, then re-encoded with MKV-compatible codecs (typically H.264 for MP4)

3

The audio stream is decoded and re-encoded (or copied if the codec is compatible)

4

Subtitle and chapter data is preserved where the target supports it

5

Streams are muxed into the MKV container and the file is saved
