Brightness/contrast “velocity” – How to turn this off?
I’m trying to make adjustments to a sequence using keyframes. Works well enough. Unfortunately, Premiere Pro (2.0) is assuming I want a “velocity” rating. Well, that wouldn’t be a big deal, but the problem goes like this:
In one scene, I have the brightness/contrast set to -14.4 / 14.4. This proceeds until frame 30. On frame 31, the scene changes, and I move the brightness/contrast to -4.5/4.5 to reflect the requirements of the new scene. Here’s where the velocity thing is a problem. Even though the value I’ve set on frame 30 is [i]very definitely[/i] -14.4/14.4, the image in the preview on frame 30 has already shifted halfway to the brightness/contrast coming up on frame 31 (-4.5/4.5), making it roughly -9.5/9.5. So what we get is every time there’s a scene change (and I’ve made an adjustment to the brightness/contrast for the new scene), the frame before the scene change has its brightness/contrast shifted in a way I did not specify.
In other words…
Specified brightness/contrast sequence (assume all are keyframes):
Frame 29: -14.4 / 14.4
Frame 30: -14.4 / 14.4
Frame 31: – 4.5 / 4.5Resultant brightness/contrast Premiere Pro outputs in the preview:
Frame 29: -14.4 / 14.4
Frame 30: – 9.5 / 9.5 (approx)
Frame 31: – 4.5 / 4.5Since this is really sort of stupid, I assume there’s a fix that is appropriately obvious, that I am missing. Anyone? ;p

A quick workaround: razor the clip at the scene change, so you now have 2 clips. Then you have a different Level FX for the next scene. No keyframes needed.
