A very large number of TV programs now use this SFX in post production. It's used almost exclusively when a single (usually panning or tracking) shot is sped up .. so that the viewer is taken from point A to B quickly without a cut being needed. It sounds like a very muffled whoosh with most of the High Frequency taken out and lasts anything between 0.5 to 2 seconds depending on the length of video it covers.
Does anyone have anything like this, or can you point me in the right direction!
(the last one is my fave but prob not what you're after)
Harri - the second one is PERFECT!
