Why are there no 1920 X 1080 Choices in the Sequence settings

Question

I watched some videos trying to understand what is the best speed and frame size to use when creating a video.  Basically Lynda.com they are saying 1920 X 1080 is full resolution and this is the desirable setting for outputting best resolution.  The aspect ratio for this is 56%.
Also they explained the best speeds for the type of output you plan to make.  So from this I naturally expected to find a High definition 1920 X 1080 setting as a choice in setting up a new Sequence in Premier Pro.  Wrong!  To my surprise there is only one choice that will give you these setting right out of the box, What's up with the settings choices.  The recommended setting should be right there and easy to find.  Below I show the choice of AVCHD is the only obvious choice for creating a 1920 X 1080 video.  Can you guys help?

Answer 1

Just to toss in my two cents worth - I don't believe any DSLR shoots 1080i, should all be progressive as 1080p or 720p. And back to the "HDV" or "Anamorphic HD" thing - with square pixels (1.0 Pixel Aspect Ratio) 1080i/p is 1920x1080 and if you divide each side of that by 120, you get 16 and 9. A 16:9 ratio between width and height (not 56% or 1.7777777 !!!!). "Anamorphic" widescreen is a way of "faking it", and saving a smaller file since less data is involved. That is how HDV works. It uses 1440x1080 pixels, and they are not square, rather they are rectangular with a 1.333 pixel aspect ratio. The pixels are wider than they are tall, and that makes up the difference so that it still plays back looking like 16:9 (IF the player respects the PAR). Simple math shows that 1440 x 1.333 = 1920! So 1440x1080 with 1.333 PAR "looks" the same as 1920x1080 with 1.0 PAR, even though 1440x1080 comes out to 4:3. Which brings up the last point, if anyone IS editing HDV footage, and wants to export to say YouTube or other other computer/tablet playback formats, do NOT export as 1440x1080 because most players will not pay attention to the PAR and the video will look like 4:3 (players wrongly assume 1.0 PAR). You will want to export as 1920x1080 with 1.0 PAR and then all is right with the world. Or take it down to 720p at 1280x720, also 16:9 with 1.0 PAR for correct playback.
