Hi, I've a high resolution video with the dimensions of 2640x2640px. The video is converted from mp4 to avi and with the image viewer I can load the video. But the video is played very, very slowly but is only 63MB. How can I play (and detect and track motion) with a normal speed? Is it possible?

I've tried it with the VideoViewer and also with the code underneath. Both with the same result.. Also with another video with 1000x1000px dimensions
videoFReader = vision.VideoFileReader('C:\Users\User\Downloads\abc2.avi');
videoPlayer = vision.VideoPlayer;
while ~isDone(videoFReader)
videoFrame = step(videoFReader);
step(videoPlayer, videoFrame);
end
release(videoPlayer);
release(videoFReader);

In my experience, VideoPlayer is slow. Try using vision.DeployableVideoPlayer instead.

The DeployableVideoPlayer object displays video frames. This player is capable of displaying high definition video at high frame rates.
