I am reading a 4k video using the following code but all frames are black!
v = VideoReader('video1.mp4');
j=1;
while j<5
video = readFrame(v);
figure,imshow(video);
j=j+1;
end

Hmm, that's odd that you wouldn't get the data, but also wouldn't see a codec error. MATLAB uses the OS' codec's for video reading and writing. Are you able to play the video correctly in Windows Media Player (if on Windows) on the same computer running MATLAB? If you're on Mac, check playing it with Quicktime. If Linux, try any program that uses GStreamer.
formats = VideoReader.getFileFormats()
