Hello,

I am trying to create an animation using VideoWriter. In between the animation, I want a frame to be paused for 10 seconds. Can anybody help me with this?

Also, is it possible to have a different frame rate for a single video object? Like, the initial frames have fps 20 while the other part have fps 10. If yes, how?

( PS: If you have answer to only one of the question, you are still welcome to answer. )

在 MATLAB Online 中打开

Adjust the frame rate this way?

video_data=VideoWriter('test_video'); 
video_data.FrameRate=5;
open(video_data)
for i=1:50
    clf;
    data=uint8(randi([0,255],[500,500]));
    imshow(data); 
    pause(randi(3)); % You have to adjust this accordingly
    frame=getframe(gcf);
    writeVideo(video_data,frame);
end 
close(video_data);

I tried implementing the code but the frame rate remains the same throughout the animation (5 fps here). In my original code I have an initial frame rate of 5 fps and I want to freeze the 100th frame for 10 seconds in the animation. Sorry if I wasn't clear in the question. Can you help me out now?
