create a 1440 x 1080 comp

Hi,

I need to create a 1440 x 1080 comp which is the same dimentional size of my video.

I tried to create a new comp and dragged my video to new comp icon, what I get is not a 16:9 aspect ratio.

The only thing I could get 16:9 aspect ratio is by selecting HDTV 1080 preset.

As this preset is designed for 1920 x 1080, my video is only 1440 x 1080. Not sure if this is the correct approach. The preview in AE looks fine to me, am I doing it right?

Why doesn't AE let me create 1440 x 1080 comp with 16:9 aspect ratio? Anyone know?

I attach a screen capture of my setting of creating 1440 x 1080 comp but this setting only give me 4:3 aspect ratio.

Thanks.
