OT real-life video display specs for iPad
I’m editing DVCPRO HD videos that will be seen on an iPad. There have been several instances where I’m forced to blow up a shot or still so that it is at more then 100% scale in the Sequence. With (maximum) iPad display in mind, I’m trying to find a compromise between pixelation from excessive blow-up vs bad design in making something too small c/o excess caution.
Without much input from the App developer people I’m trying to get a handle on the actual or effective video display specs on an iPad. We know that DVCPRO HD is 1280×1080 and the iPad 1024px by 768px at 132dpi.
It seems to me iPad’s double dots per inch (132 dpi), is sort of a red herring here. To date all our video viewing is done at 72dpi and that the iPad’s extra dpi is made for… and only meaningfully applied to fine print reading experience on e-books. That thinking leads me to believe I could blow-up an image by a third in a DVCPRO HD seq and it ok in a full screen iPad video display.
What do you all think?
Thanks in advance,
Paul

Why not just do a test on a variety of shots and see what you can live with? I think you will find it’s largely dependent on the content of the shot.
Use the iPad presets in Compressor for your encode.

Thanks John.
The iPad Compressor preset says 1280×730 (a new set of #s)
I have Compressor 3.5 but don’t have this preset, can one download these presets since it would seem Compressor 3.5 is still current?

Thanks again John,
Using the Compressor iPad preset I ran this test. (attached)
Unless I’m missing something it would appear my 1/3 guess about tolerable blow-up (130% in DVCPRO HD seq) would be about right .
