just a little technical advice about which video player works best to view our downloaded videos on laptops and desktops.
Especially Mac users should avoid quicktime player and take a look at vlc player: www.videolan.org/vlc/
It is an open source app and it is free. Vlc player shows colour and contrast of our videos the way we actually make them. Quicktime player has a different colour managment and makes our videos look desaturated and flat.
So, give it a try with vlc player if you like.
