Our new video system gives artists the power to utilize four synchronized video projectors working together to create large video compositions.On this “canvas” the artist can combine multiple video files, live video feeds, static images, and sound layers in an almost unlimited number of ways.
The diagram represents the Icebox’s unique video with four ceiling-mounted projectors represented by the red, yellow, green and blue wall projections. The long east wall to the right receives the overlapping projections from projectors “two” through “four”.
projection size information
North wall: (pixels) 1026 x 768 (feet) 26x20ft
East wall: (pixels) 2622 x 768 (feet) 72x20ft
Total combined video projection canvas (pixel) 3648 x 768
Projector “one” on the north wall is able to adjust from the corner to the center of the wall, becoming a large isolated single projection screen.
The diagram below shows an example of the various ways video might be displayed using the system. Projector One is showing a live camera feed from outside the building. Projector Two is showing the film “A Voyage To The Moon” by Melies and has some additional static cloud shapes (saved as .png files) that are floating on another layer above the video. Note how the cloud shapes enter the space of Projector’s One and Three. Projector’s Three and Four are working together to play the movie Tron in one seamless display.
The actual program used for this system is Dataton Watchout and it works, like Photoshop on the principle of layers. Movies, still images or live feeds can be layered on top of one another to create the desired effect.
Dataton WATCHOUT Technical Specifications for Artists:
Dataton WATCHOUT is a compositing tool for displaying and laying out media created using other software. Even though the ICEBOX system uses 4 Projectors (Displays), think of the interface as a single blank canvas. You will have the ability to place multiple pieces of content on the canvas, layering them together, and adjust the timing of how long you want to see it with ease.
WATCHOUT will accept most popular image formats, including BMP, GIF, JPEG, Photoshop, PICT, PNG for transparency, Targa and TIFF. IMPORTANT: In order to use Photoshop images with the system, files must be saved with “Maximize PSD File Compatibility” enabled. This Photoshop option is found under Preferences, File Handling, File Compatibility.
WATCHOUT will play back movies and videos saved in a Windows Media (DirectShow) or QuickTime-compatible format, including MOV, WMV, AVI, and Mpeg-4. The recommended video compression to use is MPEG-2.
A live video feed from an external camera or computer can be incorporated into the composition using the HDMI input.
WATCHOUT can generally play any sound file that can be played using Windows Media Player. However, the recommended sound file format is WAV. There’s usually no reason to use a compressed sound file format, such as MP3, and the additional decompression step adds unnecessary load. The size of uncompressed sound files is usually not an issue with the kind of computers used to play back WATCHOUT composition.
Some video and movie files contain an audio track in addition to the video. In this case, the sound will play from the same display computer(s) as the video does. If you don’t want this, cut the sound track out of the movie and place it in a file of its own, thereby ending up with two media files: one containing the video and one the audio. This allows you to place them separately in WATCHOUT, making the sound play from any computer. You can use QuickTime Pro or any QuickTime compatible video editing software to split the audio and video tracks of a QuickTime movie into two separate movies. In QuickTime Player, open the composite movie and choose “Show Movie Properties” on the Window menu. Select the sound track and click “Extract”. This extracts the sound track into its own movie, which you can then save as an AIFF or WAV file using the Export command on the File menu.
