HI there

I've started using videowriter to produce a basic animation of 3D surface subplots. everything works fine in terms of producing an animation, however, the rendering of the text in the figures looks rubbish.

in my code i have:

myVideo=VideoWriter(outfile);
myVideo.Quality   = 100;
myVideo.FrameRate = 4;
open(myVideo);
set(gca,'nextplot','replacechildren','visible','off');  
set(gcf,'renderer','opengl');
for ii = 1:max
      figure1=figure('Color',[1 1 1],'Position',[0.,0.,900.,900.]);
      set(figure1,'DoubleBuffer','on')
      get(figure1,'Position');  
       ****do some stuff here to produce plots****
       currFrame=getframe(gcf);
       writeVideo(myVideo,currFrame);
end
close(myVideo);

From previous experience trying to render 3D surface plots with text, i have had to create 2 separate images; one with the surface plots (opengl) but with no axis, and the other plotting only the axis and title details with painters renderer. I would then recombine those eps files to create one file using epscombine.m

My question is how can i get the text to render nicely using the getframe i.e. not to look like as it does when it pops up as figure window?

am using version (R2011a)

thanks
