Converting to FLAC won't restore lost quality
Your MTS file has already undergone lossy compression. Converting to FLAC preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your MTS file may contain AVCHD metadata metadata. FLAC has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
