Hi Anand
I think these modifications are needed :
- First of all, it's good to create an structure, containing #'nframe' rows with fileds, 'cdata' and 'colormap' , to storing movie frames. Indeed each row is corresponded to each frame.
- The construction of frames in the loop is correct, but instead of using 'moviein' , which is not recommended in new virsions of Matlab, use 'getframe' inside the loop.
- Also,using 'gca' does not preserve the labels and title in final movie file. Instead, you can use 'gcf' input for 'getframe' function, to capture whole of the figure.
- After creating and storing the frames , you can set a path and a name for final video file , create a video object using 'VideoWriter' and specify the properties for the video object .
- After all these steps and settings, now you could 'open' the video object , using 'writeVideo' function (of course outside of the 'for' loop) and 'close' the video object. Please be noted that the first argument of 'writeVideo' is the video object, and the second one is the structure of frames.
In the link below, there is some good examples of using 'getframe', especially the last one, which exactly belongs to your question, you could find another examples of using 'getframe' in the link below:
Here, I share the modified %% Movie section with you. Hope it will be helpful.
