What is MJPEG?

Motion JPEG, video stream of sequential JPEG images — stored as video/x-motion-jpeg — uses lossy encoding to handle security cameras, ip cameras, digital camcorders. Typical file sizes: varies by content.

What is VP9?

VP9 is Google's next-generation open-source video codec delivering 50% better compression than VP8 for 4K streaming.

When Should You Use MJPEG vs VP9?

Use MJPEG When...

Reach for MJPEG when your priority is security cameras, ip cameras, digital camcorders — its efficient compression makes sharing fast and storage minimal.

Use VP9 When...

Reach for VP9 when your priority is youtube 4k, web video, chrome streaming — its efficient compression makes sharing fast and storage minimal.

MJPEG vs VP9: Key Differences

  • •MJPEG uses lossy compression while VP9 uses lossy compression — both take the same approach to file size management.
  • •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •How transparency is handled: VP9 does not support alpha channels — transparent areas in the source will become opaque.
  • •Storage footprint: varies for MJPEG vs Smaller than H.264 at same quality for VP9.
  • •MJPEG is optimized for security cameras, ip cameras, digital camcorders while VP9 is designed for youtube 4k, web video, chrome streaming — choose based on your specific workflow needs
