Conversion Notes
Image conversion from JLS to VC1 preserves colour information and dimensions. If VC1 uses lossy compression (such as JPEG), compression artefacts appear at lower quality settings — use quality 85+ to minimise visible loss. Transparency (alpha channel) is preserved in formats that support it; if the target format does not support transparency, transparent areas are filled with white by default.
