Setup
Lab (Caruso)
Back projection screen
Projector design's projector
2 mic
Toshiba camera
Leif Arne's Office
Same as Caruso
Single mic
Link beetween
analog audio two ways
DVI-opticat-DVI one way
DVI-TP-DVI one way
Tests
Conduct and clap - Test 1
Over link
1 to 1: Good experience
Vivianne: Need to speak slower/clearer than when in same room
Torleif: On scale for 1-10: 9 ish. Camera infront of screen is disturbing (somewhat)
Sound sync test (clap + visual): no noticable delay
1 to 3: …
Same room
1 to 3 - conduct clap
Leif arne: Better on link due to reference line at bottom of screen
Torleif: Focused more on hands on link, most on face when in same room
Leif arne: Small movements easiers in same room
Vivianne: More aware of choir's behaviour when in same room
1 to 3 - clap-clap:
Vivianne: linear speedup easier then linear slowdown, more aware
Leif arne:
Conduct and clap - Test 2
Over link
1 -3 - conduct-clap
Vivianne: Feels more distant
1 - 3 - clap-clap
1 - 3 - conduct-clap no sound
1 - 3 - clap-clap no sound
Vivianne: Feels closer then with sound
Conduct differently when no sound (says other conductors too)
same rom
1 - 3 - clap-clap eyes closed
choir synced but lagging (Leif arne: no prediction possible)
Vivianne: stereo sound and video enables differentiating behavior of choir members
Hypoteses: Disscrapancies adds up, i.e. video link + audio link is worse than just video or just audio
Conduct and sing (ta-ta of Father Jakob)
same room 1 - 3
over link
Difference is close to non-noticable, group is getting used to both settings
Vivianne: More difficult than clapping (due to less percurrsivness)
Seem to be a fast learning curve for all
Vivianne is used to adapting (professional) ..?
same room 1-3 Leif Arne conduction
Some imprecission
over link
Leif Arne did equally well (non-professional) i.e. same room/over link does not effect performance
Choppy/jumpy effects (i.e. due to low frame-rate) are probably difficult to compansate by conductor
Need new test-workshop when delay can be introduced (with only Torleif from choir)
Video and audio delayed differently is of interest
Test different screen-sizes
Reduce video quality if possible
Conclusion: On link quality seems good enough
Faster frame rate could still make a difference
watching recorded conductor (woman):
Leif Arne saw/was disturbed by low frame rate
Vivianne and Torlaif didn't notice
watching recorded conductor (man):
He was moving his eyes (imagening looking at choir members)
Has that significance for choir?
