@andybno1 and Reno,
The best way to determine how your picture quality will finally
look is to encode a 30 or 60 second clip and test it on your
DVD player. I use WinDVD on my PC and view sample clips
all the time. I look for artifacts, blockiness, Gibbs noise, etc.
Tmpgenc preview is misleading, since the view area is small
and doesn't show the problems when enlarged on a standard
TV screen. I pick sample clips with some or all of the following,
high action, water, fire, smoke and dark scenes (shows artifacts)
These are difficult for an encoder to get right. If these types of
scenes look good the most likely the entire movie will look great.
