How do I get this incredible smooth movement?

[Aeprowannabe]

perfect!
thanks.

[Aharon Rabinowitz]

[Filip Vandueren] “smooth(width=.5, samples=25, t=time);”

[Filip Vandueren] “the width=.5 means the change is smoothed out over half a second.”

Thanks. What does the other parts of the expression mean?

Hi Aharon,

smooth is a ‘box filter’ or an averager if you will

the parameters are:

smooth(width=.5, samples=25, t=time);

width= how wide around the current time should smooth look at values to calculate an average.

samples= how many samples are taking within the width-timeframe (I allways pick a high enough value so I don’t have to constantly alter it when I tweak the width)

t=time at which we’re calculating, like a few other methods, smooth can work independent of the current time, you won’t need this often (hence t=time), or you can leave it out: it will default to the current time.

if you have fewer samples than the framerate (for example smooth(0.5, 8) you may still get some jerky motion, be sure to check the motion- and speedgraphs to see the result the expression has and you’ll see what I mean.

Anyway, about the smooth motion.
Probably trivial thing, but I haven

Thanks for the info. Enjoy your honeymoon!

That last technique — rendering to fields and then deinterlacing — suggests that the solution might be to increase the shutter angle so you get more motion blur in the final render. You shouldn’t have to render to fields and then deinterlace, you’re going to lose sharpness unnecessarily.
