WMV vs MPG: Key Differences

  • •The core technical difference: WMV relies on lossy compression whereas MPG uses lossy compression.
  • •Both formats share lossy compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Alpha channel support: MPG lacks transparency support.
  • •Storage footprint: Similar to MP4 at equivalent quality for WMV vs Smaller compared to uncompressed video for MPG.
