Hello, I am trying to exctract all frames of a video (.avi) created in another matlab script. Below the code:

if true
  %Acquisisco il percorso del FieldMovie.avi
folder = fileparts(which('FieldMovie.avi'));
movieFullFileName = fullfile(folder,'FieldMovie.avi');
%Creazione dell'oggetto 'videoObject'
videoObject = VideoReader(movieFullFileName);
%Creazione di un output folder per i frames
[folder,MovieName,extention] = fileparts(movieFullFileName);
folder = pwd;
outputFrame = sprintf('%s/Movie Frames from %s', folder,MovieName);
for frame = 1 : 129
%Estrazione dei frame dal video
thisFrame = read(videoObject, frame); % legge soltanto il frame specificato  da l'indice 'frame'
%Scrittura dell' Array Immagine nell' output file costruito di seguito
outputBaseFileName = sprintf('Frame %4.4d.png', frame);
ExtractFrame = fullfile(outputFrame, outputBaseFileName);
end
end
