What is RM?

RealMedia (RM) is a RealNetworks container format for streaming audio/video over the internet with adaptive bitrate.

What is MJPEG?

MJPEG files are built around lossy compression. Designed for security cameras, ip cameras, digital camcorders, they use the video/x-motion-jpeg MIME type and typically range from varies by content.

When Should You Use RM vs MJPEG?

RM vs MJPEG: Key Differences

• •RM uses lossy compression while MJPEG uses lossy compression — both take the same approach to file size management.
• •Since both RM and MJPEG use lossy compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Alpha channel support: MJPEG handles transparency.
• •Storage footprint: Small, optimized for dial-up streaming for RM vs varies for MJPEG.
• •Primary audience: RM is built for legacy streaming, realplayer content scenarios, while MJPEG focuses on security cameras, ip cameras, digital camcorders — pick the format that matches your output requirement.
