Both containers can carry H.264, so this conversion is largely a container change rather than a full re-encode. That keeps quality intact and makes it fast.
Resolution is capped by the target format. MKV handles up to 8K UHD material, while M4V is designed for 4K UHD, so higher-resolution sources are scaled down.
One practical gain here: M4V is streaming-friendly, so the converted file begins playing while it is still downloading.
This conversion buys reach. Unlike MKV, M4V is natively supported on macOS and iOS, which is usually the reason people convert in this direction.
Expect the bitrate to move from roughly 24 Mbps to about 12 Mbps at 1080p, and file size to follow.
Converting MKV to M4V moves the video from the Matroska container, introduced in 2002, into MPEG-4 (Apple variant), which arrived in 2005. Whether the picture is re-encoded or copied across depends on the codecs both containers accept.
Developed by Matroska.org in 2002, MKV carries H.264, H.265, VP9, or AV1 video and AAC, FLAC, Opus, AC-3, or DTS audio. That combination sets the upper bound on what any conversion can preserve.
M4V was introduced by Apple in 2005. It carries H.264 video with AAC or AC-3 audio and plays natively on macOS and iOS.
