VJ'ing Presentation at CWI

  1. 1. VJing M.W.Kauw-A-Tjoe15 december 2004, CWI, Amsterdam i
  2. 2. video art• Pioneers (1950s) • Sir Whitney Sr.• Early video manipulation gear • Video Synthesizers: analog devices from the early 70s driven by oscillators, similar to analog audio synthesizers. Create and modify video in realtime. ii
  3. 3. FairLight Computer Video Instrument (1984) Rutt-etra Video Synthesizer (1972); black & white, with a 4 bit framebuffer. iii
  4. 4. DJ/VJ Pop culture Mainstream Dance Scene DJing DJing• Radio Chat • mixing records VJing VJing• TV Presentor • motion graphics iv
  5. 5. v
  6. 6. old vj approach MixerVCR-A VCR-Boriginated in the early nineties;• pre-rendered video sources (tapes)• manipulation through • change channel opacities (blending of A and B) • apply blending effects vi
  7. 7. disadvantages• limited degrees of freedom (compared to PC)• pre-rendering takes high preparation cost• hardly any audio-visual synchronisation possible vii
  8. 8. nowadaysNo more VCRs, PC or Mac is main source of visuals!• video editing software (after fx, premiere)• 3d graphics software (maya, blender)• standard VJ software (resolume, midivid)• modular software (pd, jitter)• self-programmed stuff (kombinat, openvid)• synchronisation signal protocol viii
  9. 9. ix
  10. 10. VJ vs. filmmakerWhat are the main conceptual differences between expression through traditional film and through VJing?• live-interaction (instument-like manipulation)• strong emphasis on integration with music x
  11. 11. audiovisual syncSynchronisation enhances integration as well as interaction!MIDI is often used as a signal communication protocol • originally for audio signals • much MIDI hardware available (keyboards, drumpads, button controllers) xi
  12. 12. xii
  13. 13. xiii
  14. 14. Screen 1 Screen 2 Turntable Video Mixer Video Audio Mixer PC-1 PC-2Kombinat Midivid MIDI Turntable(widescreen) (stereo) PC-3 Logic (sequencer) Audio xiv
  15. 15. Screen 1 Screen 2 Screen 3 3x3 Matrix Openvid VideoKeys (dual screen) Mixer PC-2 Drum Pads Ableton (sequencer) VCR PC-1 PC-3 MIDI MIDI Resolume xv
  16. 16. technical analysismany ideas involved: 1 filmed footage versus animation 2 realtime playback (hardware limitations) 3 hardware & software interaction 4 realtime manipulation and generation 5 narrative and composition 6 synaesthetics 7 multiple screen display many overlapping areas! xvi
  17. 17. artPro: • video played like an instrument (dynamic manipulation) • complex abstractions possible through software generationCon: • merging the music and visuals conceptually can prove to be very hard! (sometimes they even interfere with eachother) • sometimes too decorative effect, superficial (moving wallpaper) xvii
  18. 18. worlds collide theory• (generative) video/film art• traditional VJing• computer graphics (vector, 3d, games)• (electronic) musicWhat is called VJing nowadays floats somewhere in between these domains xviii
  19. 19. conclusionVJing mainly encompasses • realtime visuals • interactive visuals • integration of sound and visionThere are many new technological and creative challenges in this domain ^_^ xix
