Expression for time remapped velocity?
Hi there. Was hoping somebody could help me. I would like to know how to write an expression that will change a motion blur amount relative to the footages timeremapped velocity. I tried using “timeremap” but this just increased the blur over time rather than when it speeds up more than the original duration. I hope you understand what I mean. Basically the effect that I want to acheive is this. When the footage speeds up it blurs more, but returns back to be un blurred when it is its original speed. I was hoping to write an expression rather than key frame it to learn more and make it easier to adjust.
Thanks for you reply

It’s going to look something like this:
minSpeed = 1;
maxSpeed = 4;
minBlur = 0;
maxBlur = 5;
linear(timeRemap.speed,minSpeed,maxSpeed,minBlur,maxBlur)Where the minSpeed and maxSpeed values are multiples of normal speed. For example, 1 is normal speed, 2 is double speed, etc.

thanks very much. This behaves exactly as I hoped. I’ve looked at your expression site too and found it very useful.
