9 Welcome Thank you, and congratulations on your choice of the Edirol V-4. The V-4 is a video mixer/effects processor that delivers image quality rivaling professional equipment, and provides four channels of video input.
10 Features of the V-4 Features of the V-4 Four-channels of video inputs The V-4 provides two S-video inputs and four video (composite) inputs. Of the four channels 1 through 4, S-video can be used for inputs 1 and 2.
11 What is V-LINK? What is V-LINK? V-LINK ( ) is a function that allows music and images to be performed together. By using MIDI to connect two or more V-LINK compatible devices, you can easily enjoy performing a wide range of visual effects that are linked to the expressive elements of a music performance.
12 Before you begin Before you begin Check the included items The V-4 is shipped with the following items. Please make sure that nothing is missing. 1. The V-4 itself 2. AC adaptor and power cable 3. Owner’s manual 4. Four screws to affix Video Fader (spare) V-4_e.
13 Before you begin Names of things and what they do Rear Panel 1. Power button (POWER) This button turns on the power of the V-4 (p. 19) 2. DC in connector Connect the power cable (DC) from the AC adaptor to this connector. 1. P ower b utton (POWER) 2.
14 Before you begin 3. Power cable hook Use this hook to retain the power cable so that it will not be accidentally unplugged. 4. MIDI OUT connector (MIDI OUT) MIDI messages input from an external device are output without change (“thru-ed”) from this connector.
15 Before you begin WHITE to fade the final output to white. Turn the dial toward BLACK to fade the final output to black. 16. Channel A input selector (INPUT SELECT) (see p. 23) This button selects the image that will be input to channel A of the video mixer.
16 Before you begin 27. Video fader (T-bar type) This is a T-bar type video fader. You can use it to switch between channels A and B, or to adjust the keying level, etc. According to your preference, you can change the orientation 90 degrees from up and down to left to right.
17 Connecting peripheral devices Connecting peripheral devices This section explains how to connect your peripheral devices to the V-4. You can connect up to four video playback devices (sources). Here’s how to connect sources such as a video camcorder, VCR, DVD player, or DV- 7PR, and play them back to create an impressive video performance.
18 Connecting peripheral devices Video signal flow The video signals received from the four input jacks are assigned to channels A or B of the video mixer. (These assignments are made manually.) The signal of A and B channels are processed by the video mixer section, and sent via the output fader to the output jack.
19 Turning the power on/off Turning the power on/off Turning the power on 1. Check the power cable Make sure that the cable from the AC adaptor is firmly plugged into the V-4. 2. Press the POWER button. Press the POWER button located on the rear panel of the V-4.
20 Checking the inputs and outputs Checking the inputs and outputs Checking the final output Here’s how to check that the signal from each source device is correctly being input to the V-4, and is correctly being output to the TV or projector as final output.
21 Checking the inputs and outputs 3. Switch the output channel Try switching the channel that is being output to the V-4’s preview monitor. Press the preview select buttons (1 through 4 and OUTPUT) one after another, and verify that the image being output to your TV monitor changes accordingly.
22 About the Memory dial (MEMORY) About the Memory dial (MEMORY) The V-4 has a memory dial that lets you store up to eight states of the panel settings. Setting 1 is fixed at the factory settings, but you can store user settings in 2 through 8. When the memory dial is at 1, the effect names printed on the panel will match the actual functions.
23 Switching two images Switching two images Here’s how to switch the images being input to channel A and channel B. Switching by Cut 1. Set the memory dial (MEMORY) to 1. To return the V4 state to the factory settings, turn the dial all the way to the left to select the #1 position.
24 Switching two images 5. Release the transformer button (TRANSFORMER) Release your finger from the transformer button you pressed. Notice that the image displayed on your TV monitor (or projector) has returned to the previous image. Switching with dissolve “Dissolve” is the effect of switching images using a gradual fade.
25 Switching two images 2. Select the input images for A and B. From inputs 1 through 4, select the images that will be input to channel A and channel B. If the same image is being input to both channels A and B, you will not notice any change when you switch between channels.
26 Compositing two images Compositing two images On the V-4 you can use Picture In Picture or Chroma Key/Luminance Key to composite the images of channels A and B. Using Picture In Picture to composite images Here’s how you can miniaturize the image of channel B and overlay it on the channel A image.
27 Compositing two images 7. Turn the effect off Press the button again to turn the effect off. Using Chroma Key to composite images You can composite two images by extracting a specified color from one image and replacing it with the other image. Such a composition effect is called Chroma Key.
28 Compositing two images 6. Turn the control dial. Parameter of Chroma Key (level of extraction) gradually changes. If Chroma Key button is not blinking, you cannot change the parameter with the control dial. 7. Move the video fader Moving the video fader will control the appearance and disappearance of the background image.
29 Compositing two images 2. Select channel A image. Play back the image that you want to use as the background. 3. Select channel B image. Input image to overlay into channel B. The image for Luminance Key should have clear contrast of light and dark.
30 Compositing two images You cannot composite images via Luminance Key if there is no light or dark aspects in the image to key off of. It may be difficult to extract correctly if contrast of light/dark is not sufficient or consistent. The default status of the Luminance Key of V-4 is set to extract the light part of the image.
31 Changing the color of the image Changing the color of the image Applying the Negative effect Here’s how to apply the Negative effect to the image being input to channel A. The “Negative” effect inverts the brightness and color of the image from positive to negative.
32 Changing the color of the image 6. Turn the control dial. Turn the control dial. The brightness and color of the image will be inverted to a negative. 7. Turn the effect off Press the button again to turn the effect off. Applying the Colorize effect Here’s how to apply the Colorize effect to the image being input to channel A.
33 Changing the color of the image Some effects cannot be used simultaneously. In addition to the Negative and Colorize effects, the color of the image can also be modified using the Posterize effect. To use the Posterize effect, you will need to assign it to an effect button of channel A or channel B.
34 Changing the motion of the image Changing the motion of the image Applying strobe motion Here’s how to apply a Strobe Motion effect to the image being input to channel A. “Strobe Motion” is an effect that thins-out the frames of the image, producing the impression that the motion is being halted at intervals.
35 Applying the Multi or Mirror effects Applying the Multi or Mirror effects Applying the Multi effect Here’s how the image that is input to channel A can be divided on the screen. You can divide the image vertically, horizontally, or both vertically and horizontally.
36 Applying the Multi or Mirror effects Applying the Mirror effect Here’s how the image that is input to channel B can be divided and inverted. The result is as though a mirror were placed in the center of the screen. The image can be inverted vertically, horizontally, or both vertically and horizontally.
37 Switching in synchronization with music Switching in synchronization with music The V-4 can switch images in synchronization with the beat of the music.
38 Switching in synchronization with music Using the tap (TAP) function to switch images As an alternative to specifying the BPM numerically, you can use the tap button (TAP) to specify the timing at which the images will switch. 1. Input images to channels A and B.
39 Applying an effect on the music Applying an effect on the music The V-4 cannot only switch images but can also apply effects in time with music. You can use the BPM or TAP functions to apply effects that are synchronized with the music, as in a VJ performance.
