i like playing just 1 card at a time...i dont play a card while im doing something on my computer....
Then set the size slider to something between 90% and 100% depending on your own personal tastes. Use less than 90% if the girls are still too tall for you.
If you do set the slider to between 90% and 100% with "do not zoom over 100%" unchecked then, depending on just what size you choose
All clips will be the size you have selected
The 3k and 4k clips will ***** no noticable degradation
The 1080p clips will be zoomed by between 120% and 133% so they will be slightly degraded
The 720 clips will be zoomed by between 180% and 200% so they will be more degraded
The 480 clips will be zoomed by between 270% and 300% so they will be highly degraded
If you want the 1080p clips to ***** no degradation then either tick the "do not zoom over 100%" and accept the fact that their girls will be shorter than those in the 3k and 4k clips or reduce the size slider to 75% and accept the fact that the girls in all clips are smaller than they are with a higher size setting. Choose whatever combination best suits your own tastes in these matters.
When I said "The 3k and 4k clips will ***** no noticable degradation" that is because the 3k clips will be reduced in size from their native size by the factor set on the size slider so if this is not 100% the 3k clips will be very slightly degraded due to the small rescaling from their native vertical 1440 pixels which just happens to match your screen. The 4k clips will be being recaled from their native resolution anyway as their native vertical resolution is greater than your screen's 1440p.
