Supports: MPG, MPEG
WMV (Windows Media Video) is Microsoft's video format, designed for Windows Media Player and Windows-based streaming:
WMV plays in Windows Media Player without additional codecs. MPEG may require codec packs on older Windows systems.
Competitors like changemyfile.com reports "a 500MB MPEG file converted to a 280MB WMV with no visible quality loss." WMV's compression is more efficient than MPEG-1/MPEG-2.
WMV was designed for internet streaming from the start, making it suitable for Windows-based media servers and intranets.
Competitors like changemyfile.com explains "MPEG developed in early 1990s for DVDs and broadcast, WMV from 1999 optimized for Windows streaming — better compression means smaller files at similar quality." runconvert.com notes "MPG files open natively on almost all platforms without external codecs."
