Hello, I tried this code:
h=figure;
movegui(h, 'onscreen');
rect = get(h,'Position');
rect(1:2) = [0 0];
vidObj = VideoWriter('H1,H2.avi');
vidObj.Quality = 100;
open(vidObj);
for it=1:Nt
t=it*dt;
H1(1) = 1;
figure(1)
h=plot(x,H1,'--',x, H2,':','lineWidth',2);
title({['H1 and H2 in the wake region'];['time(\itt) = ',num2str(dt*it)]})
xlabel('Spatial coordinate (x) \rightarrow')
ylabel('(H1), (H2) \rightarrow')
legend('H1', 'H2')
movegui(h, 'onscreen');
hold all;
if ~mod(t,0.1)
saveas(gcf, ['t=',num2str(t),'.png'])
end
for i=2:Nx
H1(i)=...
end
end
close(vidObj);
Why I cannot see any movie and I get the error message above?

Post the complete error message, such that we do not have to guess which of the 2 movegui commands fails.

movegui(h, pos) requires the first input to be the handle of a figure. But inside the loop h is the handle of the line object created by plot().
Because the figure does not change its size inside the loop, you can omit the movegui command there.
Some improvements:
hFig = figure; % a better name than simply "h"
...
figure(hFig); % Not hardcoded [1]
...
movegui(hFig, 'onscreen'); % Or omit this line!
