GEOMETRIC EFFECTS AND CROP

Introduction:

The VJX16-4 allows you to apply one of the following geometric effects independently onto each track:

• Left Mirror (MirrorL)
• Right Mirror (MirrorR)
• Mirror Up (MirrorU)
• Mirror Down (MirrorD)
• Horizontal Flip (FlipH)
• Vertical Flip (FlipV)
• 180° Rotation (Rot180)
• Blow (Blow)
• Scroll (Scroll)
• Mosaic (Mozaic)

It also offers a series of Motion Fx for each track, which act upon the fluidity of the video:

• Freeze
• SlowMotion
• Strobe
• Bloc (Scramble the moving parts of the image)

Additionally, you can also crop any of your video tracks with the Crop function.

The VJX16-4 allows you to define the zones around the selected track and edit the characteristics (opaque or transparent) with the Bkg. Alpha (Background Alpha) function.

Here are the controls which are used to configure all of these effects:

First of all, choose which track you wish to modify or apply geometric effects upon. To do this, press the SELECT button of the track which you desire (see SELECT FUNCTION chapter).

Geometric Effects Fx:

To modify or apply a geometric effect Fx on the video track you selected; press the Fx button. This button will light up green and the LCD screen will display the geometric Fx effects menu:

• On the 1^st line, the type of effect is displayed. By default, no effect is selected: OFF.
• On the next 3 lines, is a drop-down menu which you navigate with the rotating wheel (JOG ).
• If you want to apply one of these effects on the selected track (for example, Scroll) you just have to go down the menu until the effect you desire appears next to the cursor. Select by pressing ENTER to activate the chosen effect. If you want to deactivate it, press the ENTER button again and you will return to the list of geometric Fx.
• If you wish to apply a different effect on your selected track, just press BACK to return to the main menu and choose another effect.
• Certain effects are configurable and others not. To modify these parameters, use the 4 knobs and the Trackball of the shared controls

Here is a description of the different geometric effects Fx:

These are the controls used to configure the Scroll effect:

Once the Scroll effect is activated, the LCD screen will indicate the following information:

Tip n°1:

• The ZoomX parameter indicates the level of horizontal zoom.
• The ZoomY parameter indicates the level of vertical zoom.
• The X parameter indicates the level of horizontal scroll.
• The Y parameter indicates the level of vertical scroll.

Tip n°2:

• The horizontal and vertical zooms are [1 ; 63] in the range of values, the default value being 1.
• The horizontal movement is in the range of values [-720 ; 720], the center being 0.
• The vertical movement is in the range of values [-576 ; 576] in PAL and [-480 ; 480] and NTSC, the center being 0.

Tip n°3:

• The 3^rd knob controls simultaneously the ZoomX and ZoomY parameters.
• The Trackball controls the X and Y parameters.
• ScrollWrap: Another way of managing the Scroll effects. When the video exits the screen, it reappears on the opposite side.
• ScrollX: This wrap effect controls only the horizontal wraps.
• ScrollY: This wrap effect controls only the vertical wraps.
• ScrollWrapX: This effect manipulates ScrollWrapX to wrap only horizontally.
• ScrollWrapY: This effect manipulates ScrollWrapY to wrap only vertically.

Mosaic

This effect creates a mosaic using the original video.

Mosaic

Here are the controls which you will need to configure the Mosaic effect:

Once the Mosaic effect is activated, the LCD screen will display the following information:

Geometric Motion Effects:

To modify or apply a geometric Motion effect on the video you selected; press the Motion button. The button will light up green and the LCD screen will display the geometric Motion effect menu:

• On the 1^st line the different type of effect applied is shown. By default, if no effect is applied, it will show: OFF.
• On the bottom 3 lines, is a drop down menu which you navigate by turning the rotating wheel (JOG).
• If you wish to apply one of the effects on the selected track (for example the Freeze effect), you just need to navigate down the menu until the effect you desire appears next to the cursor. Then press the ENTER button to activate the chosen effect. If you wish to de-activate it, press the ENTER button again and you will return to the list of geometric Motion effects.
• If you wish to apply another effect to the selected track, just press the BACK button to return to the drop down menu and choose another effect.
• Certain effects are configurable and others are not. To modify these possibilities, use the 4 knobs and the Trackball of the shared controls.

Here is a description of the geometric Motion effects:

Motion Fx Off

De-activation of all Motion effects.

Freeze

This effect freezes the video.

SlowMotion

This effect makes the video appear in SlowMotion.

Here are the controls which you will need to configure the SlowMotion effect:

Once the SlowMotion effect is activated, the LCD screen will display the following information:

The Rate parameter indicates the number of fixed images (N) over the total number of images (P).

Tip n°1:

• N is [0 ; 150] in the range of values.

Tip n°3: The Rate parameter is the same for the SlowMotion and Strobe effects.

In the example displayed on the LCD screen, there are 5 fixed images out of 25.

Strobe

This effects allows you to create flash video.

Here are the controls which you will need to configure the Strobe effect:

Once the Strobe effect is activated, the LCD screen will display the following information:

Tip n°1:

• N is [0 ; 150] in the range of values.
• P is [2 ; 150] in the range of values.
• N is always inferior or equal to P (N ≤ P)

Tip n°2:

Geometric Crop effects:

To modify or apply a geometric Crop effect on the video track selected, press the Crop button. The button will light up green and the LCD menu will display the geometric Crop effects menu:

• On the 1^st line the type of effect applied is indicated. By default, if no effect is applied, it will show: OFF.
• On the bottom 3 lines, is a drop down menu which can navigate by turning the rotating wheel (JOG).
• If you wish to apply one of the effects on the selected track (for example the Crop effect), you just need to navigate down the menu until the effect you desire appears next to the cursor. Then press the ENTER button to activate the chosen effect. If you wish to de-activate it, press the ENTER button again and you will return to the list of geometric Crop effects.
• If you wish to apply another effect to the selected track, just press the BACK button to return to the drop down menu and choose another effect.
• Certain effects are configurable and others are not. To modify these possibilities, use the 4 knobs and the Trackball.

Here is a description of the geometric Crop effects:

Crop Off

De-activation of all Crop effects.

Crop

This effect allows you to trim the borders (left, right, up or down) to delete certain zones of the video which you do not wish to display (like, for example the border effects on a camera or DVD player).

Crop

Here are the controls which you will need to configure the Crop effect:

Once the Crop effect is activated, the LCD screen will indicate the following information:

Helpful Hints:

• The 1^st knob controls the L parameter that indicates the proportion of the image which is cropped on the Left.>
• The 2^nd knob controls the R parameter that indicates the proportion of the image which is cropped on the Right.>
• The 3^rd knob controls the U parameter that indicates the proportion of the image which is cropped Upwards(Up).>
• The 4^th knob controls the D parameter that indicates the proportion of the image which is cropped Downwards (Down).>
• The Trackball controls the 4 parameters at once and allows you to move the border too.

CropCenter

This effect is identical to the Crop effect except that it is always centered on the image. The L and R parameters are always identical. The U and D parameters are always identical.

BackGround Alpha geometric effect :

This effect allows you to define the properties of the zones in the video which have been deleted (by the Crop or Scroll effect). This zone can be:

• Either totally black and opaque (The Bkg. Alpha button will be switched OFF).
• Or totally black and transparent (The Bkg. Alpha button will be switched ON).

This function is really useful for doing P.I.P. (Picture In Picture).

Left: Bkg. Alpha de-activated. Right: Bkg. Alpha activated

• In the first example, the track on Layer A has been cropped. The edges are black and opaque because the Bkg. Alpha of the track on Layer A is de-activated. The track on Layer B is invisible.
• In the second example, the Bkg. Alpha of the track on Layer A is activated. The track on Layer B is visible only where the track on Layer A has been cropped.
