The Freeze effect immediately freezes the selected video source. You can freeze up to
two video sources, then transition between them while retaining the freeze – that is,
the freeze stays in MXProDV’s memory until you specifically release it.
This section describes the types of freeze effects you can produce with MXPro and
how to use Freeze with transitions.
You can also use the Freeze effect with the MXPro PIP and Compose features. Refer to
Chapter 8, PIPs, and Chapter 9, Compose, for further information.
Field and Frame Freezes
You can freeze either a video field, or a full frame.
Field Freeze – Captures every other horizontal line of the video. This is ideal for
capturing anything in motion.
Frame Freeze – Captures all horizontal lines, thereby producing a higher resolu-
tion (better quality) image. Use Frame Freeze when working with still images,
such as photographs. Using Frame Freeze with images in motion normally pro-
duces jitter in the image.
MXProDV captures using Frame Freeze, by default. See “Force Field Freeze” on
page 90 to learn how to change the default setting.
