Variable speed fast - slow motion?

Here's one for you! - I'm trying to make a clip in Premiere go in a linear fashion from 4 times normal speed right down to slow-mo and then stop, all in the one shot. It's not actually possible, is it? Not without a million pounds of pro-gear probably.

Or am I very wrong?

Snake,

It should be possible in Premier, put your clip on time line as usual, and using the razor tool slice your clip into chunks, make the first chunks speed 400% then decrease the speed slightly in the next clip. Repeat this process (the more you do this, and the smaller the chunks, the smoother the effect will be.). Continuing as you get down to a very slow speed, you should be aware that as Spped goes under 100% it becomes noticable, (due to interlace etc) Alan Roberts suggested a very nice way of improving things by placing a the same clip on a different video track one frame out of synch and decreasing the oppacity of this clip. I'm affraid I can not remember the exact details but I'm sure if you did a search on this board you'll find it! AR's solution did sound like a very good work around for the problems of reducing the clips speed. I think what you wish to do will certainly look better for the ammount of time and detail you spend working on the clip. Good Luck and it would be interesting to hear how you got on.

If you are using a canopus product they make a small program called speed controller which will do this

System 2: AMD X2 5600, M2NPV-VM, 2GB DDR2, Geforce 8600GT 256 DDR 3, 450GB Total drive space, RTX100 with Premiere Pro 2

Thanks for the replies, guys. Good idea about splitting the clips - What I've done is take the same clip and copied it several times and rendered a number of different speed versions of the same clips and taken them back into Premiere ( using AR's suggestion for slower clips, which works great) - Now, I can speed up and slow down at will with variable speed by cutting the clips together at the same relative frame -
Cheap and groovy!
