v = VideoReader(path);
vidHeight = v.Height;
vidWidth = v.Width;
mov=struct('cdata',zeros(vidHeight,vidWidth,3,'uint8'),'colormap',[]);
numFrames = get(v,'NumberOfFrames');
for k=1:numFrames
mov(k).cdata = read(v,k);
end
Then I will apply some change to the mov, but I cannot output a video using VideoWriter or VideoFileWriter, as it says something like the input does not correct
Is that mean I cant use any of them to convert a struct to a video? What else can I do? Thanks

Videofilewriter step method only accepts individual image arrays (or y cr cb arrays).
Videowriter writeVideo method only accepts individual image arrays or individual frames compatible with movie structure (your mov is an array of those)
You will need to loop writing the contents of your mov structure array.
