This project consists of a series of studies on algorithmic video. They investigate the opportunities for dynamic spatial montage offered by digital video. Found footage excerpts are fed to different algorithms that manipulate the pixels of the videos in real time.
Algorithmic videos SLIT SCAN and TIME SCULPTURE experiment with the temporal dimension of the video. They visualize simultaneously areas of past and future frames of the same video. The projects REAL-TIME VIDEO MIX and TU/TWO investigate interactive ways to compose and mix multiple videos in real time.
REAL-TIME VIDEO MIX
In REAL-TIME VIDEO MIX, areas of a video are replaced by the corresponding areas of another video in real time, according to the selections of the viewer.
Software: C++ (OpenFrameworks).

In SLIT SCAN fragments of past and future frames of the same video are visualized simultaneously. Every horizontal line of pixels visualizes the corresponding pixels of a future frame. This transformation adds fluidity to the forms, freeing them from spatiotemporal constraints.

In TIME SCULPTURE, pixels of past and future frames of the same video are visualized simultaneously in circular concentric areas around the point selected by the viewer.
Every future frame of the video is placed in a different depth, creating a virtual 3D volume out of 2D video-frames. This way, the time dimension is transformed to a third spatial dimension.

In TU // TWO the movement of the performer is used to create a dynamic mask that makes areas of different videos, simultaneously visible.
A computer vision algorithm detects the movement of the performer and uses this information to process the image of multiple videos, that are simultaneously reproduced at multiple layers. TU //TWO can be presented both as a performance as well as an interactive installation, permitting the audience to experiment with the influence of their movement on an audiovisual composition.
Developed with: Processing
