Progressively speeding up a clip sequence

[bironic]

I'm rebuilding a vid after a computer crash, and I want to recreate a specific effect at the end but am wondering if there's an easier way to do it. Do you know:

a) The term for the effect where a sequence of clips goes ever faster, until you reach a climax where you're looking at one or two frames each? See for example the last 20 seconds of the

Time remapping (in After Effect and also in later versions of Premiere) with keyframes will allow you to do one continuous speed increase.

I thought time remapping was to speed up the action within a clip, rather than to make the length of each succeeding clip shorter (without altering the speed within them)? (Does that distinction make sense?)

Ah, sorry -- I misread your post and missed the "sequence" part! The hazard of replying before coffee.

I suppose you *could* use time remapping, though not in the way I was originally thinking: lay out all of the clips you want to use in a pre-composition (or new sequence in Premiere), making each clip of equal length, then apply time remapping to the pre-comp/sequence to gradually speed it up and reduce the number of frames that get shown from each. Probably not a great method, though, since the action would of course be sped up and you wouldn't have a lot of control over exactly what was featured.

If nothing else, that might provide a template to then move my actual clips on top of....

hey is there a way of doing that same effect with Sony Vegas? Do you like just use Velocity?
