
Main Profile (MP)
This profile provides improved picture quality at reduced bandwidths and storage costs and
is becoming more common as the camera processors (DSPs) become more able to handle
the processing load. Main Profile can save 10-30% over Baseline.

High Profile (HP)
High Profile is the primary profile for HD broadcast and Blu-ray HD disc media applications. It
can save 10-30% of the storage cost over Main Profile. However, it may also increase video
latency, depending on the stream structure. Quasar models default to the Main Profile to
provide the best trade-off between storage size and video latency.
