No, converting MMF to MOD does not cause additional quality loss — MOD uses lossless compression. However, any artifacts already present in the original MMF file will persist in the MOD output.
MOD files are typically 2-5x larger than equivalent MMF files because MOD preserves all pixel data. This is expected and necessary for lossless quality.
