    I should know the answer to this question, but for some reason its not there.

    I am creating a promo video for a 40 inch monitor. Specs given are: max resolution: 1366×768. 16:9 aspect ratio. THe monitor boasts 770p resolution.

    I select the HD/HDV 720p preset (1280×720) in AE but it sets the default as square pixels. The final project is going to DVD, so I am assuming it should be set to non-square pixels. Am I correct in this?

    Also when I import my footage into FCP they have a pre-setting for 960×720 and 1280×1080 but I cant seem to match the dimensions in AE (1280×720)

    Anybody with HD experience?

    Thanks in advance,

    Steve

    you’d want to double-check your monitors specs, as a true 1280×720 720p HDTV uses square pixels, as does a 1080p 1920×1080, but this 1366×768 business makes me think your monitor uses rectangular. Anyway that’s why AE uses square by default.

    btw here’s a nice article i dug up while researching this subject for my own knowledge…

    https://hd1080i.blogspot.com/2006/12/1080i-on-1366×768-resolution-problems.html

    i’m still not clear myself about the best PAR to work with…it would seem you could go ahead and work at standard 1280×720 at 1:1 and the monitor will scale it up to 1366 (likewise if you want to work at 1920×1080, it’ll scale it DOWN). As the article indicates, the quality of this scaling depends largely on the particular model of monitor….you’re either getting more pixels for your buck or getting screwed out of quality with no control over how it is scaled.
