Hi,
I am makign the video from the images, code run fine and making a video but that video is just white background instead of the images. Does anyone know what I am doign wrong here. Below is the code.
Code:
imgFile = dir('*.jpg') ;
%N = length(imgFile) ;
v = VideoWriter('newfile.avi');
%v.Quality = 95;
open(v)
imgFile = dir('*.jpg') ;
for i = 1:179
img = imgFile(i).name
frame = getframe(gcf);
writeVideo(v,frame);
end
close(v);

Hi muhammad,
Note that gcf opens an empty figure if a figure is not already open, in which case the empty figure would be captured by "getframe" function and written to the video file throughout the loop.
You can refer to the examples provided in the documentation for the "writeVideo" function for reference on adding images to a video file using "writeVideo".
Hope this helps
