please clarify the workflow for exporting footage

[cakewalkr7]

We're shooting footage with the HV20 for training videos and webmercials which will al be online. So, the output format will be square pixels. I'm shooting in the HDV 24p mode and the way I'm doing it is..

1. Capture with premiere
2. Import the mpeg into after effects and do my compositing
3. Export at a 16x9 format.

That seems to work fine except that after effects reads the file as 1440x1080 and without turning on the pixel aspect ratio correction option in the preview window, it's stretched height wise. I have to set up an output module to resize the video to a 16x9 format. As I said, that is working fine but I didn't know if any of you have a smoother workflow to export from premiere to a square pixel format without having it resize the video down to 720x480 (I think that's the correct dimensions). I know that 720x480 should be fine, but some of what we're doing involves keying which I do in AE, so I'd like to have the larger resolution file to have more edge information and get cleaner keys. Does it sound like I'm making things too difficult or is there an easier, more straightforward way? Thanks.

I don´t really understand why you resize to 720x480 before you are done with your project. Can you not stick to 1440x1080 in the whole process?
Resizing should be the last step before compression for the web.

That's one thing that confuses me. When I start a new project in premiere and select the hv20 preset for hdv 24 it says the frame size is 1440x1080. But when I then try to export>movie, the dimensions are 720x480 and they're grayed out so I can't change them. So, I'm not intentionally trying to resize it down to that in premiere. It's just that that seems to be the only option I have. Therefore, rather than doing that I just open the mpeg directly in after effects and edit/composite there.

Maybe the preset is b0rked - can´t you just manually set the right values?
Are there any Premiere users here that can help, I do everything directly in AE.
