HD is usually Square pixels.

so i set up a sequence in FCP. a preset that is 1440 X 1080. i then rendered out a slug and brought it into AE. i dragged it to the “new comp” icon and it gave me a comp that is 1920 X 1080 with an aspect ratio that is “Non-square (1.33:1)” and a frame rate of 25 FPS.

Why not try a 1920×1080 preset? It should give you a comp size of 1920×1080 with 1:1 pixels (square)

Yep, 1920×1080 is 16×9 square pixels:

1920/16 = 120
1080/9 = 120

Since we have a common factor for height and width at 16×9, we’re talking square pixels here. 🙂 So use the 1920×1080 square pixel preset.

Watch the Aspect Ratio when you create the 1440×1080 composition. It’s going to stretch your pixels to the non-square 1.33 ratio as you saw when you brought the slug into AE.

Just make a 1920×1080 sequence in FCP and set the Pixel Aspect Ratio to square instead of leaving it at the 1440x1080HD preset.

one other twist. i exported a slug from FCP using the preset there and it is 25FPS. the preset in AE is 24 FPS. what gives ?
