hi

there are 50 frames in the folder HEART in C drive. i need to convert them into video. following codes i have written. the problem is there is slight mismatch between frames appearance when movie is played. I mean frame 50 gets played before 48. and 50th frame plays in place of 48. what is the problem with these codes.

pathname ='C:\HEART\' ;

dirlist = dir( [pathname '*.jpg'] );

pickind='jpg';

for x = 1:length(dirlist)

i = imread([pathname,dirlist(x).name]);

figure,imshow(i),title('load frames');

F(:,x)=getframe;

end

implay(F)

also the video i am playing is very fast . i need to get codes for playing it at my desired speed. kindly help fast. i am in urgent need for solution to this problem
