creating images and make a movie in matlab

I have a code tracking particles in a pipeline. I used

scatter3(x,y,z)

and then

baseFileName = sprintf('%03d.png',  iw)

to createimages from particle displacement and then used VideoWriter function to make a video from those images. The output video doesn't shows a smooth particle movement and there are jumping at some points. Is there any advice to fix the problem?

Many thanks in advance.

I recommend putting in a brief pause() between generating the plot and capturing the current axes, to give time for the graphics to update.

See my attached demo where I create a movie from a series of plots I make with surf().
