Hey, I'm very new to this and I could be asking a very simple and stupid question that's probably been asked before.
I have a couple of Nikon photography cameras that also record HD video; a D3100 DSLR that records 1080(can't remember if i or p off the top of my head) and a Nikon Coolpix L310 that records 720p.
Now the issue I'm having is this, when I transfer the footage I film to either my iMac or my PC it looks great if I have it in smallish window, say standard youtube size. However it becomes far from HD when I view in full screen or any larger size (very grainy). Now I can't say much about the L310 but I have seen footage allegedly from a D3100 that maintains its HD at full screen.
Is this possibly because I am viewing on non HD monitors? I ask because despite them not being HD monitors, when I watch HD video on Youtube I have been able to watch a perfectly crisp picture at full screen.
Is there something I'm missing.
Thanks for the help.
