I have recently received a first gen iPad Mini. My experience with Handbrake is limited. Can anyone recommendation what settings to use on Handbrake to convert HD source ( mostly 1280 x 720 ) to watch on the smaller 1024 x 768 screen without losing more quality than already lost from the smaller resolution, but also without making the files bigger than they have to be. I would also like the video to take up the whole screen without borders ( I don't mind if it stretches a bit ).
As usual, the answer is “it depends” because viewing quality is subjective, space is less of an issue on a 64GB iPad than a 16GB iPad, and a desire to use Airplay means you need a higher resolution file.
Your best bet is just to start with the iPad preset and start increasing the Constant Quality/RF factor until you don’t like the quality.
