Hello all,

I am having issues exporting a video and want to make it high resolution:

vidObj = VideoWriter('moviev.avi');
vidObj.Quality = 100; hold on % 1) trying to make video obj high res
vidObj.FrameRate = 1;
open(vidObj);
figure('units','pixels','position',[30 30 1920 1080]); hold on % 2) trying to make resolution high 
for k = 1:numel(whole_ts)-1   
  plot(whole_ts(k:k+1), ts(k:k+1), '-blue'); hold on
  pause(0.0001)
  set(gcf,'renderer','Painters'); hold on % 3) use painters to try to make resolution high
  frame = getframe(gcf); hold on
  writeVideo(vidObj, frame);
   
end
close(vidObj);

I have tried both line 1, 2, and 3 in order to make the output image high resolution - but the avi image still comes out blurry. Do you have any suggestions?

Thanks!
