I have an ultrasound video clip and I want to plot it as a 3D rendered. I want to use 'Volume Viewer' app but when I upload either of the video clip, the single frames, or the voulumetric data, it gives a format error.

I attached the videoFile here, then I applied this code to generate the volumetric data.

videoFile = "address.mp4";
videoReader = VideoReader(videoFile);
numFrames = videoReader.NumFrames;
frameSize = [videoReader.Height, videoReader.Width];  % Dimensions of each frame
volumetricData = zeros([frameSize, numFrames]);  % Initialize the 3D matrix
for i = 1:numFrames
    frame = read(videoReader, i);  % Read the i-th frame
    % Preprocess the frame (if needed)
    % Register the frame (if needed)
    
    volumetricData(:,:,i) = rgb2gray(frame);  % Convert the frame to grayscale and store in the 3D matrix
end
% Step 5: Visualization and rendering
% Display the 3D rendering using volume rendering
figure;
h = volshow(volumetricData);  % Display the volume rendering
