What is M2V?

MPEG-2 Video (M2V) is a raw elementary stream of MPEG-2 compressed video, commonly used in DVD and broadcast.

What is SMK?

SMK files are built around lossy compression. Designed for vintage pc game videos, retro game asset extraction, game preservation, they use the video/x-smacker MIME type and typically range from varies by content.

When Should You Use M2V vs SMK?

M2V vs SMK: Key Differences

• •The core technical difference: M2V relies on lossy compression whereas SMK 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.
• •Transparency: Not supported in SMK
• •Storage footprint: Larger than MPEG-1, 3-10Mbps for M2V vs varies for SMK.
• •Primary audience: M2V is built for dvd video, broadcast tv, mpeg-2 encoding scenarios, while SMK focuses on vintage pc game videos, retro game asset extraction, game preservation — pick the format that matches your output requirement.
