| ===List of Cards===
| | This is the processing engine behind the [[Maurice]] control unit, a fact that has lead to some confusion, and many people calling a [[P164]] a [[Maurice]]. |

| ===Framestoring===
| | It provides range of video processing functions in real time, thus making a very useful machine to have around in the days before computer edit suites, or for live events. As a result whilst the unit in the studio vision path is rarely used in the way it used to be, units are regularly used on outside broadcasts either to Genlock a free-running video source or to provide some urgently needed video manipulation like zooming a projector feed or keystoneing a warped picture. It can also be used for aspect ration conversion, for example, a 4:3 video source can now be fed into the anamorphic 16:9 vision path, after being "squished" to 75% space horizontally. |
| The P164 can genlock a free running signal onto an external sync.
| |
| * Place the free signal in one of the P164's 4 inputs. If it is valid video, then the corresponding Red L.E.D will light.
| |
| * Connect a lock signal to the P164's Genlock/Sync Inputs.
| |
| * Navigate menus tree, set genlock to ON.
| |
| * Navigate menus tree, select the video source.
| |
| * Job done.

| ===Mixing===
| |
| This P164 Has the Built in mixer Card installed. but the control panel doesn't know that, so until the P152 is going, you cant do this.
| |
| | |
| ===Aspect mirphing===
| |
| Aspect ratio change:
| |
| * Choose source
| |
| * EFX1 in menu tree
| |
| * Hsize > change so picture is:
| |
| ** 0.75x original for 4:3 into a 16:9 vision path (squish so black down sides)
| |
| ** 1.33x original for 16:9 into a 4:3 vision path (stretch, no black), or 0.75x on the Vsize instead. (stretch, bars top & bottom).
