Generation loss — quality may degrade
MTS uses lossy compression, and so does AVI. 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 MTS file may contain AVCHD metadata metadata. AVI 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
AVI 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 MTS to AVI
Your MTS video is transcoded — video and audio streams are decoded and re-encoded into the AVI container. This is a lossy process that takes time proportional to the video duration.
Your MTS file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with AVI-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 AVI container and the file is saved
