No, converting H263 to FLC does not cause additional quality loss — FLC uses lossless compression. However, any artifacts already present in the original H263 file will persist in the FLC output.
FLC files are typically 2-5x larger than equivalent H263 files because FLC preserves all pixel data. This is expected and necessary for lossless quality.
