Demo to extract frames and get frame means from a movie and (optionally) save individual frames to separate image files. Then rebuilds a new movie by recalling the saved images from disk. Also computes the mean gray value of the color channels and detects the difference between a frame and the previous frame. Illustrates the use of the VideoReader and VideoWriter classes.

I'm using matlab R2019a. Demo works great for extracting images from video, work with them and then saving them. The problem I have is that when I try to create a movie with the images matlab shows this error:
"Error: Frame mus be 451 by 231"
This is really strange because I hadn't change anything in the code.
Any help would be greatly appreciated.
I have struggled for a long time to find something that looks at video features at a low level. Thanks
I was wondering if it would be possible to adapt your function to read out Facial regions of interest from a video, save them into a folder and then load them back into a Matlab as a video?
It would be easier if it had a .fig file (GUI) is there any available?
Thank you for the basic framework for video processing. One of the best works by Image Analyst.
Thank you for this tool. This is very interesting and useful!
A nice starting place for video processing. Shows how easy it is for beginners to get into. Great job!
