    Anyone have experience with other shows at Asiaworld? Are the displays usually out of sync?
    Given that sound travels at about 300m/s and that the arena might be 150m deep the basic laws of physics say that by the time the sound reaches the back or the arena it's going to be about half a second delayed from the video. (Half a second is a pretty noticeable delay.) So my guess is that the video was deliberately lagged by that fraction of a second so that for the people at the back of the hall (who needed the video) the two would be in sync.

    I've never really thought about this before, but it's pretty obvious when you do.

    PDLM - that was what I was thinking too, it would be nice to have this confirmed by any sound engineers who may be reading !

    i was at the back, slight out of sync as well, the long throw speakers (presumed video screens were delayed fractionally) were not sync, noticable, but did not spoil the occasion.
