Veejay is a live performance tool featuring simple non-linear editing and mixing from multiple sources. You can load
multiple video clips, cut and paste portions of video/audio and save it as an EditList. Also, you can record new clips
from existing clips or (live) streams. With these clips you can change playback speed (slow motion/acceleration),
change the looptype and set markers.
With both clips and streams you can edit the effect chain and mix from multiple sources to one. Veejay has a 84+
effects, divided into two categories: Image and Video Effects, only with Video Effects you can select a channel to mix
in.
Veejay has many frame blending methods, some of these are: Additive,Substractive,Difference Negate, Relative Addition
and Selective Replacement. Next to blending, you can key on Luma and Chroma seperatly or combined or simply use
Transitions or other effects.
Most edit and navigation commands are mapped to single key press commands, this allows you to control, depending on
the playback mode, video navigation, the effect chain, effect parameters and clip properties at playback time.
Also, you can record a new clip on the fly from a live feed or from the video clip you are playing. If requested, the
recorded videofile will be added to the edit descision list and activated as a new video clip. This is particular
usefull for time-looping,rebouncing and rough clip scratching/editing
Veejay can be remotely controled through using OSC (Open Sound Control) or via its own internal message interface
'VIMS'. 'VIMS' allows you to create/load/save effect chain templates and to add customized events which can be
triggered by a keypress or a remote message.
Veejay supports streaming from multiple video sources to one, this can be a Video4Linux device , a vloopback device or
a yuv4mpeg stream. You can chain several veejays with effectv and vice versa to create some amazing footage.
