I have a lot of stuff, SD, however I'm starting to just download HD from now on, more importantly if you buy the HD version, you also get the SD too you can download, might as well get the HD version, money permitting of course.
Keep in mind that what matters in the end are not the pixel dimensions (i.e. width and height of the video in pixels), but the actual resolution of the source material. You can blow up a standard definition video to 1920x1080, but that doesn't magically increase the resolution. 😉The iPad since iPad 3 runs QHD resolution. Higher then 1440p. So yes. HD is best option.

In my experience the quality of iTunes 1080p videos is rather low when compared e.g. to Blu-ray (which is not surprising, since iTunes HD files are far more compressed). This is really obvious on big screens. I doubt the resolution after compression is anywhere near "real" 1080p, much less even higher resolutions. Combined with the small screen size, there is a point of diminishing returns ...
Close. 😉 I'm implying that the strong compression that is used to achieve the small file sizes removes so much fine detail from the image that it doesn't even fully utilize 1920x1080. If you watch iTunes HD movies on a big screen and compare them to a good Blu-ray, you'll see that they have a lot less fine detail and look soft (not to mention frequent compression artifacts such as color banding).So you're implying that the source videos of movies are lower than 1080P? 😱😱😱
I think what you mean is detail or picture quality not resolution. Upsampling does give you a higher resolution video but it doesn't give you more detail or better PQ (at least not without some complex madVR post-processing or something). At best, you just get as much detail and PQ as the source video.Keep in mind that what matters in the end are not the pixel dimensions (i.e. width and height of the video in pixels), but the actual resolution of the source material.

The term resolution is today often used in a wrong way. It doesn't really mean the pixel dimensions, but the ability to resolve details. Even analog film, which does not have a fixed amount of pixels, has a resolution. It is measured in the maximum amount of "lines" per unit length that can still be distinguished. In that sense, compression (or more generally lowpass filtering) can lower the resolution of a digital image even if the pixel dimensions remain the same.I think what you mean is detail or picture quality not resolution.
