How do you save video from matlab?

Answer 1

To save a video in MATLAB, you can use the VideoWriter class. First, create a VideoWriter object specifying the filename and format (e.g., 'myVideo.avi'). Then, open the video file using the open function, write frames using the writeVideo function, and finally close the video file with the close function. Here's a simple example:

v = VideoWriter('myVideo.avi');
open(v);
for k = 1:100
    frame = someFunctionToGenerateFrame(k); % Replace with your frame generation
    writeVideo(v, frame);
end
close(v);
