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().
