Converting to BMP won't restore lost quality
Your MTS file has already undergone lossy compression. Converting to BMP 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. BMP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

Common Mistakes When Converting MTS to BMP
"Converting MTS to BMP will improve the quality"
No. MTS has already permanently discarded data during compression. Converting to BMP preserves what's left but cannot restore lost detail. The file will just be larger.
"BMP will be smaller than my MTS file"
BMP uses no compression, so the output file is often larger than a lossy MTS. If you need a small file, BMP may not be the right choice.
