In your animation since the images have to be written to video in a specific order, parallelization will not really help as you still have to wait for the nth image to be read and written until the (n+1)th frame is written. I believe VideoWriter has made some performance improvements in 18a as per the release notes. Maybe this should help speed up yyour operation.
convert jpg file to animation problem

Hi:
I tried to convert a series of jpg files to a movie. but the created .avi file could not be open.
I attached the sample code and test file, could someone give me some suggestions?
clear all
clc
load test_name
v = VideoWriter('test.avi');
open(v);
for ii = 1:length(test_name)
fprintf('operating on file: %s.\n',test_name{ii})
F=imread(test_name{ii});
writeVideo(v,F)
end
close(v);
by the way, the test code I attached operate the file one by one. assuming that I have 1000 frames, is there anyway to optimize it to parallel computing?
Thanks! Yu
