Assuming that you have the script that was used to create the video, you can modify the script and use the "savefig" function after the figure plotting code to save your created figures as a ".fig" or an image file.
% Replace with your figure generation code!
for i = 1:numFigures
% Generate figure
fig = figure;
plot(data{i}); % Replace with your plotting code!
% Save the figure
savefig(fig, sprintf('figure_%d.fig', i));
% Optionally save as an image
saveas(fig, sprintf('figure_%d.png', i));
% Close the figure
close(fig);
end
Alternatively, you can use the "VideoReader" function to read your ".avi" file and then loop through each frame of the video. Assuming that each frame represents a figure, you can then save the frame as an image using the "imwrite" function after reading the frame using the "readFrame" function.
videoFile = 'your_video_file.avi'; % Replace with your video file name!
v = VideoReader(videoFile);
% Frame counter
frameNumber = 1;
% Loop through each frame
while hasFrame(v)
% Read the next frame
frame = readFrame(v);
% Create a filename for the image
imageFileName = sprintf('frame_%04d.png', frameNumber);
% Save the frame as an image
imwrite(frame, imageFileName);
% Increment the frame counter
frameNumber = frameNumber + 1;
end
