性价比极高的四进三出视频混合器,包含多种高品质视频效果器。你可以在任何需要视频展示的场合应用此设备。

·4通道输入视频混合器/切换器

V-4配有4个RCA输入,外加两个S-Video(Y/C)输入,并且A/B双通道自动选择。

·大量不同的转场效果

V-4内置效果包括溶解、硬-软边卷帘,以及超过240个Wipe模板。

·超过90种视频效果

可以在A,B通道中单独添加静态、Strobe效果,以及Negative和Colorize等滤波效果,以及多屏显示、画中画、抠像、亮度控制等等。

· 独立的2通道TBC/帧同步器

输入源通过独立的2通道TBC(时间基准校正)电路来校正时间码,在当前阶段独立的2通道帧同步器用来校正两个输入源。这个处理过程可以保证流畅的转换效果,确保所有时刻图象都非常稳定。

· 预览功能

通过输入源选择按钮可以控制预览功能,可以让用户监视单独的输入1-4,或者是在转换之前的输出效果,这样便不需要多预览的的监视器了。

· 输出的淡入淡出

为输出添加淡入淡出效果。

· TAP功能完美演示音乐与视频的融合

通过TAP敲入节拍,便可根据当前的音乐节奏快速切换视频或效果。

V-4的用户功能可以记忆并重新调出不同的设置,如指定到每个按钮上的效果。即使是电源关闭了,内存依然保留,所以你可以保存一些你经常使用的设置,最大的数量为8个。

·专业的视频推子

T型视频推杆用于快速而直观地操作。V-4的革新之处是你可以选择你喜欢的工作方式,可以垂直操作视频混合器,也可以象DJ那样水平地操作推子。

· 四输入/三输出设计

V-4采用了四输入、三输出的简洁设计,你可以在任意两个输入源间进行切换和混合。A/B双通道支持独立的TBC(Time Base Corrector),可以实现任意输入源的平滑切换。V-4可以用于多种演出场合、发布会,比如VJ、现场摄像切换或是为线性或非线性编辑提供素材。较低的投入、高品质的演示效果正是V-4最重要的特征。

独立的双通道TBC

V-4为A/B通道分别提供了独立的TBC,它保证了在DV、S端子和VHS、Hi-8进行视频切换和混合时的平滑过度。

· 高品质画面

因为内部的4:2:2全数字处理,V-4可以生成高于500线的高品质画面。你可以混合DV品质的视频图像,而没有任何衰减。

· 高质视频效果和多种Wipe模板

The V-4 is a 4-channel Video Mixer made for portable or fixed installation use. It is ideal for use in nightclubs, places of worship, theatres, and other live performances. The compact design of the V-4 gives you the freedom to make your video sources come alive. The V-4 is a part of the EDIROL SD video mixer line. See the SD Mixer Comparison.

For cutting-edge Multimedia artists, the V-4 offers V-LINK, an exciting new feature from Edirol and Roland that provides for realtime performance control over digital video, for the ultimate in creative expression. V-LINK allows the user to trigger clips, perform video effects and transitions in real-time when connected with the Edirol PR-80 (sold separately). The V-4 video mixer also has MIDI in/out/through, for real-time or sequenced control of video sources with effects and transitions.

Video Mixer / Switcher with 4-ch input

V-4 is equipped with four composite (RCA Pin) inputs plus two S-video (Y/C) inputs. V-4 offers scene transition of the four video sources with Dissolve, Wipes (with a total of about 200 variations), and Switching. The V-4 outputs the same video source to all the three jacks (Composite x 2, S-video x 1), for simultaneous monitoring and displaying, without resorting to external distribution boxes.

Professional Video Quality

The input video sources are processed completely in the digital domain, and give professional video quality (13.5MHz, 8-bit, 4:2:2, DV quality). Ideal for use on large screens, and because the V-4 internal processing is digital there is no quality loss.

Independent 2-channel TBC / Frame Synchronizer

The input sources go through independent 2-channel TBC (Time Base Correction) circuits to correct the time code, independent 2-channel Frame Synchronizers are also applied to the two sources at this stage. These processes enable smooth transitions and Dissolves, and ensuring stable images all the time.

Independent 2-channel Digital Effects

V-4 features independent 2-channel Video effects that include a rich selection of digital effects (refer to spec sheet). The V-4 also features composition effects such as Picture-in-Picture, Chroma-key, and Luminance-key. The effects are recallable by a single button press.

Professional-use T-Bar Video Fader

Professional-use T-Bar cross fades for quick and intuitive operation. A V-4 innovation is that you chose to attach the fade however you like, either, vertically as standard for video mixer, or horizontally as a DJ mixer fader. The fader resolution has over 100 steps and offers extremely smooth transitions. Its metal body as well as its fader is strong and durable to be used in your active performance.

Easy Operation

V-4 is designed for its functions and operations to be clear from the front panel. Because it is simple to use its easy-to-use operation will enhance your realtime performance. Most of the V-4 functions can be selected and controlled without resorting to the manual.

Preview Function and On-Screen Menu

The preview function is controlled by the source selection button, and enables the user to monitor each of the input sources 1-4 or the output source before transition, to a single preview monitor, no more multiple preview monitors! You can control V-4's major functions (Ex. Effect selection, MIDI input setting, etc.) from the dedicated preview screen using the convenient On-Screen Menu. This is separate from the output to the main outs, so you can view it anytime you want.

Convenient User Memory Function

V-4's User memory function allows you to memorize and conveniently recall the panel settings, such as effect assignment to each button. The memory is saved even while the power is off, so you can store the frequently-used setting. Maximum eight configurations.

Synchronization between Audio and Video/Connection with MIDI Equipment

The V-4 features video transition/effects that can be synchronized with MIDI. The BPM (beat per minute) of transition/effects can be made to follow the beat of a music track by hitting the tap button (TAP function). The functions of V-4 can also be controlled via MIDI equipment such as a MIDI keyboard controller. If you have the optional PR-80, various visual performances become even more creative by mixing the DV-7PR's numerous video clips with the V-4's visual effects, all with realtime transitions and composition.
