Save frames while creating a video

3 次查看(过去 30 天)
I'm doing a video from a data array (ArrayVelocity). The data is composed the next way: files with Columns and rows (representing X and Y direction from the 2D image) and each file means an isntant of time.
The code goes as follows:
for i=1:size(ArrayVelocity,3) %Checks the lenght of the time vector
[x_1_range, x_2_range, matrixVmag] = buildMatrix(meanArray(:,1), meanArray(:,2), ArrayVelocity(:,colVmag,i)); %Brings the information from the array
txtTitle = "";
plotContour(time(i), x, y, matrixVmag, txtTitle); %Function to plot the data
%Creates the video
frame = getframe(gcf);
writeVideo(v,frame);
close
end
I want to get the image of each instant of time (or frame) and save them in a folder.
I'm stuck with that alrerady some time. I would appreciate your help!
Thanks :)

The code above does and saves the video correctly...I also want to save each frame separately.

From the frame structure, you can probably just use the cdata field to write to file as an image using imwrite so long as you know how to name the frame and where you want to write the file to.

I solved the problem by adding two simple lines:
fname = 'R:\Frames\'; %Direction of where is going to be saved the each frame
saveas(gcf, fullfile(fname,['Frame' num2str(i).png'])) %saves frame with file name
Thanks :)
