Its easy to download the media uploaded to your project through the Weddingmix app.
Login to your weddingmix account. Then go to your status page. (The one where you can see all your photos and videos.)
Then on the RIGHT-HAND SIDE you will see a button marked DOWNLOAD GUEST UPLOADS.
Click on that. Then chill for a minute as it bundles the media for you.
You will known your media is ready to be downloaded when that button reads DOWNLOAD BUNDLE.
Click on it and it will ask you where on your computer you want to save your media.
BOOOM! Done :)
Now, if the above doesn't work for some reason try it from your gallery link.
Click BUNDLE ALL CLIPS FOR DOWNLOAD. Wait for it to read DOWNLOAD BUNDLE.
And your all set!
