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.
Expect the bitrate to move from roughly 15 Mbps to about 24 Mbps at 1080p, and file size to follow.
MKV dates from 2002 and is not natively supported by modern browsers, so plan on a desktop media player for playback.
Converting TS to MKV moves the video from the MPEG-2 Transport Stream container, introduced in 1995, into Matroska, which arrived in 2002. Whether the picture is re-encoded or copied across depends on the codecs both containers accept.
Developed by MPEG in 1995, TS carries MPEG-2, H.264, or H.265 video and AAC, AC-3, or MP2 audio. That combination sets the upper bound on what any conversion can preserve.
MKV was introduced by Matroska.org in 2002. It carries H.264, H.265, VP9, or AV1 video with AAC, FLAC, Opus, AC-3, or DTS audio and plays natively on Windows.
