Hello, I've been trying out your Tempo demo for a couple of weeks. My main use of it would be for architectural fly-bys and walk-thrus. I've been experimenting with starting out with a uniform velocity path and then trying to vary the velocity at very precise locations along the path. Let's say I have a circular path going around a building and decide to slow down at segment AB (say frame 300 to frame 600 in a 1200 frame animation) to get a longer look at some important feature. I go to the velocity curve editor and move the points at these frames but when I check out the results in the preview I find that the resulting physical position and length of the velocity change don't match the AB segment where I wanted the slow-down to occur. What strategy is used to make these align? In the keyframer I could simply double the number of frames within AB and scale back down to the original number of frames. Can this be achieved as easily and accurately in the velocity curve editor? Or is more a fine tuning tool? Is there much trial and error involved in using Tempo? Thanks in advance for any feedback you can provide. George Sandoval
