Help! Video compression stuck in last step!!

Ok... this is my last attempt to complete my project: Video Compression using DCT in matlab. I am attaching the source code files in this question. My video compression works in 3 steps. Step 1: (EXTRACTION.m) Extracts frames from a video then saves in a folder named "Snaps" and at the same time selects alternative images and stores them in "Newsnaps" Step 2: (DCT.m) Performs DCT on the folder "Newsnaps" and stores them in new folder "Video" Step 3: (FORMATION.m) Reconstructs an avi format video from the folder "Newsnaps". i got stuck in the last step. So any help will be great!! Waiting for the reply! P.S. The video is "abcd.avi" and it is in monochrome. The folder "Newsnaps" and "Video" needs to be created before execution and path must be set.

You forgot to explain the occurring problem with any detail. "I got stuck" does not allow us to guess, what you are struggling with. So what kind of help do you expect?

It is not cute to start a script with the brute clearing header "clc; close all; clear all;". Why removing all debugger breakpoints when the debugger would be the best assistant to find a bug?
