i have two vedio of mp4.i want to apply some tranformation on it and run the tranform vedio.i have wriiten the code but contently facing the error.i even tried "NumberOfFrames" but it is unrecongnized in my matlab
code is here
% read videos
vid1 = VideoReader('video1.mp4');
vid2 = VideoReader('vedio2.mp4');
% read first frame from each video
frame1 = readFrame(vid1);
frame2 = readFrame(vid2);
% create a figure
fig = figure;
while hasFrame(vid1) && hasFrame(vid2)
% read frames from each video
frame1 = readFrame(vid1);
frame2 = readFrame(vid2);
% perform geometric transformations
frame1_scaled = imresize(frame1, 0.5);
frame1_sheared = imresize(frame1, [size(frame1,1) size(frame1,2)*0.8]);
frame1_rotated = imrotate(frame1, 30, 'crop');
frame2_scaled = imresize(frame2, 0.5);
frame2_sheared = imresize(frame2, [size(frame2,1) size(frame2,2)*0.8]);
frame2_rotated = imrotate(frame2, -30, 'crop');
% concatenate frames
combined_frame = cat(2, cat(1, frame1, frame1_scaled, frame1_sheared, frame1_rotated), ...
cat(1, frame2, frame2_scaled, frame2_sheared, frame2_rotated));
% display frames
imshow(combined_frame, 'Parent', fig);
drawnow;
end
error that i facing is
Error using cat
Dimensions

consistent.
Error in untitled (line 27)
combined_frame = cat(2, cat(1, frame1, frame1_scaled, frame1_sheared, frame1_rotated), ...
