Question

LINEAR (not curve) velocity change (for position)

I need to have a smooth, linear deceleration across a number of graphics (in this case, horizontal scrolling titles that are too long to have in a single instance).

I recon the best way to do this would be to have each decelerate at a constant rate, with the next clip starting at the instantaneous velocity value of the end of the prior clip.

The velocity controls in the effects panel seem quite good at "natural" changes in velocity (using bezier curves), but how about this far simpler effect that I need? Any ideas would be helpful.

    It would help to see a screen shot of your Effect Controls panel and Timeline panel — or at least the title in question. I'm not sure what you mean by "linear deceleration across a number of graphics."

    Why not just place your very long title in one graphic and then animate it across the clip(s)? Below I have a very long title graphic that extends far beyond the width of the clip. I zoomed out to 10% in the Program Monitor.

    The graphic extends across multiple clips in the sequence.

    Your screenshot shows precisely what I am trying to do.  The problem however is that my title is far longer than that, and exceeds size that PPro can handle. This is why I'm exploring breaking it into sections.   I'm trying to create a smooth deceleration overall, which would need the velocity at the beginning of a clip to match the velocity at the end of the prior clip.  I can eyeball it for sure, but seems like there should be a way to do it precisely.

    I suspect that these controls have something to with it, although changing their values seems to have zero effect.

    How long is your title? And how are you determining "long"?

    This is not making sense to me somehow.

    Set keyframes to Linear.

    Been trying that.  No change, except that the curves of the slopes are less extreme.  Seems to me that if it's linear, there should be no curve in the slope. Thanks though.
