Loop using im2frame https://www.mathworks.com/help/matlab/ref/im2frame.html

writeVideo can accept a numeric array of rgb images, and it can accept a strut array of frames that can be pseudocolor, but it cannot accept a numeric array of pseudocolor images even if they have the same colormap.

There are also ways to batch convert a numeric array of pseudocolor to a numeric rgb array if the same colormap is used for all of them, but I do not know of any built in or file exchange contribution that does that.

I've written a function based on this method described by Walter. Walter is attributed within the documentation of the function.

Download gif2avi() from the file exchange.
