Generation loss — quality may degrade
TS 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 TS file may contain PSI/SI tables 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.

What Happens When You Convert TS to MKV
Your TS 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 TS 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
