What is a frame synchronizer? A frame synchronizer is a digital device that stores a frame of video in its memory and releases it at a very precise moment. These little devices are essential if you want to make a seamless switch from one video source to another. If the sources you are switching between are not synchronized with each other, the video image falls apart at the transition moment, and the result is not pretty.

For more information, see Controls and Operations page 22 and Output and Monitor, page 13. Some General Notes on Installation There are a few other things to be aware of when you are installing and integrating the SE-800. Please make sure you have read the Warnings and Precautions section on page 3.
Power up State When you first power up the SE-800, you will need to make channel assignments and set audio levels. Transition and effect settings are not retained please refer to Preset Bank on Page 35 for function keys setup (see Using Transitions, page 35 and Using Effects, page 41 for details). At power up, channel A will be the selected Main Video Source and channel B will be the selected Sub Video Source.
RCA plugs (also sometimes known as phono plugs, cinch, or tulips) are used for line level audio, such as the connections between a CD player and amp. The SE-800 uses these in stereo pairs, white for left and red for right, at the audio input and output sections. 1/4 inch jack plugs got their name, some say, because they used to be used to manually patch together phone lines in the old central switchboard days.
Using SE-800 SDI Overlay interface for CG Text overlay Using SDI interface (270 Mbps, SMPTE 259M standard) and the EXT Chroma-Key effect on SE-800 to communicate with a PC SDI CG overlay card and perform a text overlay for the output video, page 45. GPI Trigger A GPI (General Purpose Interface) trigger is connected here by means of a mini plug (1/8”). This device allows you to make the SE-800 do certain things at the specific moment you press the trigger, such as making transitions and effects happen.
Quick Start We’ve made three sample application set ups for using the Switcher: Production studio; Multi-camera event (city council meeting, church service, etc); and Performance (club VJ, concert visuals, etc.). Pick the one that most closely approximates your initial intended use, follow the block diagram to make the video and audio connections, and jump in to using the controls.

Selecting video input formats and adjusting audio levels (Numbers refer to the Front Panel illustration above) *. Verify that there is a valid source at each input you’ve connected by using the Main Source Select buttons (4.) to select a channel and view the output on the main monitor. For each input channel (A, B, C, D): press the top Input Format button (7.) to select the channel, then press the bottom button to select the proper video format. DV = digital video through FireWire (a.k.a.
Cutting between sources The simplest way to cut (switch) between source video inputs: use the Video Main Source buttons (4.) to select which input goes to the program monitor (output). Look at the results on your program or record monitor. Dissolving between sources Select the Main Video Source (4.) by pressing the appropriate channel button. The LED for the channel you have selected should be lit and you should see that source on the program monitor. Select the Sub Video Source (5.
pressing the up and down arrow keys; sizes are numbered 1-8 and displayed in the Effects window above the Keypad. Alternately, you can enter numbers 1-8 on the Keypad. There are 3 options for how much of the image is affected; PIP/Mosaic effect can be selected by pressing the PIP button in Mosaic mode, press the PIP “Up”, “Down” arrow keys for Mosaic/PIP picture size which can be positioned using the Joystick (3.).

1. Audiometers: LED style meters, which show the signal strength at the Audio Output. The signal they measure is determined by the sources selected by the Audio Bus selectors (22.) and the levels set by the Faders (21.). The LEDs turn red at +9 dB to indicate clipping distortion. For more information, see Audio Inputs, Levels, and Meters, page 32. 2. Audio Input Selectors and Level Controls: Controls which audio input channel (A, B, C, and/or D) is sent to the Audio Bus Video (VCR) channel (22.
6. A+V: Audio follow video switch. When this button is engaged (you’ll know it is engaged because the LED is lit), the audio associated with a selected input source automatically follows the video through the dissolve. When the button is inactive, audio must be switched manually. For more information, see A+V, page 34. 7. Input Format selectors: These buttons allow you to select the input video format for each channel.
11. Mode: selects the T-Bar operating mode of the SE-800, between Video (default), Audio, GPI, and Play. For more information, see Mode select in the Using Transitions section, page 35, and Mode select in the Using Effects section, page 41. 12. T-Bar: used to manually perform a transition. For more information, see Playing a Transition Manually, page 35. 13. Chroma Key: when engaged, this removes the selected color from the Main Video Source and reveals the corresponding portions of the Sub Video Source.
16. Mosaic: when engaged (and the Mosaic LED is lit), this turns the selected Main Source Video into a mosaic of colored squares. There are 8 mosaic patterns to choose from, selected by repeated presses of the up and down buttons. The effect can be applied to the whole image or one of two window sizes, which can be positioned anywhere on the screen. For more information, see Effects: Mosaic, page 42. 17.
21. Faders: sliders to control audio levels for the Main audio output mix. Each is active when the LED on the Audio bus selector button (22.) above it is lit. For more information, see Audio Inputs, Levels, and Meters, page 32. 22. Audio Bus selectors: the LEDs indicate which of the audio inputs are active in the Main audio output mix. Press the button to either include or exclude the channel. The left button, labeled Mic/Aux, can be set to either Mic, Aux, or off.
Video Source Selecting the Main and Sub Video Sources is the first thing to do when setting up the SE-800. The source you select (by pressing one of the buttons; a bright red LED on the selected button lights for confirmation) on the Main Source bus is what is sent to the Video output. This means that you can perform cuts between sources by simply pressing different buttons. (If A+V is engaged, video and audio from the selected source will switch together. See A+V, page 35 for more details on this function.
Input Formats This is the second thing to do when setting up your SE-800 for use: select the input format for each channel you’ll be using. These controls are active as soon as you push the upper channel select button. They become inactive when you have cycled through all 4 channels or when you press a button in any other control except the Color Processor.
(Brightness, Contrast, Color, and Tint) are pressed. U stands for Unity, or perhaps Unchanged. In either case, it shows that the signal passing through that particular control is being neither boosted nor cut. To see the settings for another control, press either one of that control’s buttons. To change the settings, press the up and down arrow buttons. You can see the extent of color processing available in this section by experimenting with the controls.
If you don’t have any video test equipment, follow the suggested procedure to adjust all the video sources, which is described at the end of Appendix: Monitor Calibration, page 55. Settings made in this section are “remembered” by the SE-800 after you power down the unit. In other words, these settings remain in effect until they are changed or either the Reset or the Reset All button is pressed.
Audio Inputs, Levels, and Meters (Headphone, faders, bus selectors,) These Audio Input Channel Selectors and Level pots are the first stage in the audio signal path. Each channel carries the audio associated with a video input. Analog audio comes in through the RCA connectors on the rear panel; audio from the DV input is converted to analog and passed to this bus.
These faders correspond to the selector buttons above and control the relative volume of each input in the master output as well as the master output level. They are called faders because they are used to decrease (rather than increase) the signal levels to make a balanced and pleasing mix. When they are set at Unity, at 6, they pass the audio signal through at the same level it was at when it entered this bus. This is why level setting at the Input Bus is so important.
Voice sync *. VOICE SYNC” function is only available to correct the Audio input from the selected “Video” (A, B, C or D) channel. When engaged, this control allows you to compensate for delays in the video as it travels through the various components, processors, and converters of the Switcher, so that the video maintains sync with the audio.
Using Transitions Transitions are the centerpiece of the SE-800’s functionality, sort of its reason for being. (Would the SE-800 still be a Switcher if it didn’t do transitions? This is the sort of philosophical question that will be dealt with in volume 2 of this manual: SE-800, an Observer’s Manual.) The SE-800 can do 4 kinds of transitions: cut, fade, wipe, and zoom.
Auto-play The Take-button automatically plays the selected transition between the selected sources. Parameters (effect variation and speed) are displayed in the windows above the Keypad. See the next section below for more information. Using the Keypad to customize a transition The windows at the top of this section display parameter data relating to the selected effect.
Mode selects and use The default mode for the SE-800, and the one you will use most often, is Video. In Video only mode (Video LED is lit), the T-Bar operates as expected and as described everywhere in this manual. In Video + Audio mode (Both LED are lit), the T-Bar switches Video and the Audio between selected sources. In Audio only mode (Audio LED is lit), The T-Bar switches Audio volume high/low of the selected source In GPI mode, transitions and effects are played by the trigger (see below).

Using Effects The SE-800 is capable of producing a wide variety of digital effects. These fall into 2 categories: single channel and dual channel effects. Single channel effects are produced on the source selected in the Main Video Source bus and need no second video input. Single channel effects include Strobe (MISC), Freeze, Mosaic, and Paint. For example, select any input channel having a valid signal as the Main Video Input. Press the Freeze button once.
Freeze This effect freezes the incoming video, as selected on the Main Video Source bus. Simple as that! There are no parameters, no variations. Press the button once, and the video freezes, press it again, and it returns to the selected source in full motion. The Freeze effect is single channel, and can work in conjunction with any transition. MISC MISC Mode will have more features added.
1 = large window is the affected area 2 = small window is the affected area To position the Mosaic window effects, press the button under the Joystick until the LED for Position Control is lit. Then you can use the joystick to position the effect in real time, anywhere on the screen. When you exit the effect, the position will be remembered as long as the Position Control LED is lit. This means that the next time you activate the Mosaic effect; the position will remain the same as previously.
Border These controls are used in conjunction with the Picture in Picture Effect and the Zoom and Wipe transition only, and can only be activated when either the Picture in Picture or Zoom control is active. With the On button’s LED lit, parameters for Style, Color, and Border Softness can be set by pushing the appropriate button. There are 2 Styles available: thin and thick. These choices are cycled through at each button press.
Chroma Key When engaged, Chroma Key removes the selected color from the Main Video Source and reveals the corresponding portions of the Sub Video Source. To engage this effect, select sources in the Main and Sub sections. Then, press the Chroma Key button once to select video as the key overlay (INTL LED will light), press a second time to select EXT (LED is lit) for PC/MAC SDI CG overlay, and a third time to select both.

Tech Notes Books are written about many of the topics below, large and complex books. Look for them if you want more information than what we have presented here. What we want to do here is to provide a bit more in depth information, deeper background, on some relevant topics, and give you a framework for further technical investigations. Video Standards, Formats, and Quality Video standards refer to the broadcast and/or viewing systems; they are specific to certain regions of the world.
The point of all this technical information is ultimately to help you to make high quality video: video that looks good and serves the purpose for which it is made. But how do we know if the video is of high quality? And what does that really mean? There are certain technical standards that video must meet simply in order to be viewable on a monitor. And beyond that fairly cut and dried realm is the area of aesthetics.
broadcast systems between NTSC and PAL, but much of the usage will be the same. You can use the SMPTE bars regardless of where you are and what video system you are producing for, just as you can use EBU bars wherever. You’ll notice that the EBU bars don’t have the gray scale information The first thing to do is to get the color bars displayed on the monitor you want to calibrate. And then, locate the image controls on the video monitor, as these are the ones we will be adjusting.
For each input you plan to be using, have a valid signal and adjust the Color Processor controls on the SE-800 in this order: 1. Set contrast to midpoint; turn color all the way down so that the image is gray; 2. Adjust brightness until the image shows shadow detail and no blown out highlights; 3. Adjust contrast until just before the highlights bloom; 4. Bring the color control back to its midpoint; adjust hue so that the skin tones look natural; 5.
