Karaoke
In addition to being able mix musical video clips, the video engine of VirtualDJ also
makes it possible to play karaoke files
VirtualDJ compatible with the files is karaoke as well with format DVD CDG
(as well MP3+G, WAV+G, WMA+G, OGG+G, etc...) as well as zip files.
When you use CDG files, VirtualDJ posts in the explorer of files two files for each
song:
• The first, having an icon with "K" blue, is the video karaoke file. If you drag and
drop on a turntable, VirtualDJ automatically will load the audio track on the turntable
and the words on the video.
• The second, having a normal icon, is the audio file only. You can use it in your mix
audio when you wish to use the music without words. This file will not cause the
loading of the texts on the video.
Lastly, you can also bind files CDG with their audio counterpart directly in a file. ZIP
(in which case only the file karaoke-video will appear in the explorer of VirtualDJ).
In order to avoid indexing all the files. zip present on your computer,
VirtualDJ does not consider by default the zip files karaoke. If you use it will
be necessary you to add in the options "extension" the extension ZIP, and
to associate it the decoder of karaoke.
10 - Connections and Use of External
Peripherals
VirtualDJ can be used just as it is, however the majority of the professional users will
not be satisfied mixing with Just a keyboard and mouse. Fortunately, VirtualDJ is
compatible with several configurations for external mixers and peripherals.
Use of Headphones
VirtualDJ includes the ability to pre-to listen to a track with the headphones without
having to send it to the main output. VirtualDJ has the following three sound
configurations:

Transition effects
When you mix from one turntable to another, you can use different plug-in to
transition from one video clip to the other.
By default, 4 transitions are installed (cut, insipid, zoom and cubic), but many others
are available on our website www
.virtualdj.com
The video can use a separate cross fader (located in the central window under the
"Video" button in the default skin), or you can in the options link the video cross fader
to the audio cross fader in order to use only the traditional audio cross fader.
Also, in order to enrich your mix video, you can apply video effects.
Some effects are installed by defect, but many others are available on Internet site
www
.virtualdj.com or http://freeframe.sourceforge.net/Video 21
(Attention, certain effects use all the potential of the modern video cards and are
likely not to be compatible with all the video cards. Refer to the documentation of
each effect).
You can also easily create your own effects if you have some knowledge in programming.
A SDK is available on our website www.virtualdj.com
The realizable field of the applications with the video effects is very vast (improvement
of the image, tunnel effects, web cam, posting of SMS, etc etc).
Optimization
The mix video remains much heavier in resources than mixing audio, also certain
optimizations will be perhaps necessary for full frame rate video, especially if you
want to use files DVD in high definition.
Several parameters determine the speed to which VirtualDJ decompresses and
displays its video. Mainly, they are the quantity of memory present on your video
card, the speed of your graphics processor (GPU), the speed of your main frame
(CPU), and incidentally the speed of your hard disk. Also, the type of file played
influence largely. A file mpeg1 is indeed faster to decompress than a file.vob
(contrary to the generally accepted ideas, a file DVD.vob is not a "not-compressed
file", it is a file compressed in mpeg2, the standard of compression of the DVD). In
the same way, a file in 320x240 is faster to decompress than a file in 720x576.
By defect, VirtualDJ decompresses only one of both videos loaded if the cross fader
is such as only one will be visible. It saves machine time thus and makes it possible
the software to turn on weaker configurations. However, that may result in small jolts
at the time of the transitions. If your configuration is sufficiently powerful, it is
advised to notch the box "decode while hidden" to obtain more fluid transitions.
Lastly, if you use a full-screen output, it is more effective to use a card having two
outputs, rather than to use two separate graphics boards.
In all the cases, it is much more effective to use a mode of resolution with the same
number of colors on your video exit as on your principal exit.
And finally, it is not used for nothing to choose a resolution much higher than the
resolution of your video files. A resolution of 800x600 will be sufficient if you use files
DVD highresolution, if not choose a resolution of exit of 640x480.
