I usually export pictures and encode them with a separate encoder.
With mencoder, this works like this:


fps = 15;
length = 5;
Export["mathematica-plot-"
     <> ToString[NumberForm[#, 3, NumberPadding -> {"0", "0"}] ]
     <> ".jpg",
    Plot[f[t/fps, x], {x, 0, 10}],
    ImageResolution -> 100] & /@ Range[0, length fps];

Run["mencoder \"mf://mathematica-plot-*.jpg\" -mf fps=" <> ToString[fps=
] <>
    " -o mathematica.avi -ovc lavc -lavcopts vcodec=mpeg4"];

This generates a movie of the time evolution of f[t,x] from t=0 to t==
5
with a framerate of 15 frames per second. You should be able to adapt
this for a 3D ListPlot easily.
