No, converting OGV to Y4M does not cause additional quality loss — Y4M uses lossless compression. However, any artifacts already present in the original OGV file will persist in the Y4M output.
Y4M files are typically 2-5x larger than equivalent OGV files because Y4M preserves all pixel data. This is expected and necessary for lossless quality.
