Re: Premiere to AE. Where to begin!?

Alright sweet as, Im nearly out of questions, so heres my final few.

Once ive finished applying these effects, is it easy for me to bring the edited project back into premiere pro and finish the audio? Im going to follow your advice and not touch it in AE, but i will need to fiddle with the volumes once its done, but i just want to make sure all the effects will stick to the shots when i bring them back. Secondly, if i backed up my premiere project, and then chose not to import the audio into AE, how will i get my audio back on once if finished in AE? I imagine the solution is related to the first question, its just that if i export it as a premiere pro project and then copy the audio from the backed up version onto this new project, It never seems to stick.
eg. Ill open an older pp save that has all the same project files, copy a section of the timeline. close the project. open the new save that has all the same files, paste the copied timeline section in. All seems to work fine. save. close project. But when i open back up, the copied timeline sections will be blank.

Hope that makes sense. really just need to know how to stick my audio timeline back on, and how to get the project back in pp once im done.

Last but not least, the premiere project is set at 29.97 fps, frame zize: 1440x1080 16:9, with a pixel aspect ratio: HD anamorphic 1080 (1.333)

The AE comp with the imported save is on HDV 1080/29.97 1440x1080 and a pixel aspect ration of HDV 1080/DVCPROHD 720 (1.333) 16:9, 29.97fps.

But for some reason, the footage from the pp project, once opened in AE appears to be sqeezed. If i change the AE comp settings to HDTV 1080/29.97, it seems to regain its widescreen format. I just thought this is strange seeing as HDTV is at 1920x1080 and the original footage is at 1440 x 1080 and yet, it looks correct when on the HDTV setting.
strange no?

Thanks again for your help, i know the first question is a bit stupid, but i dont want to go through all the hassle of applying effects to find i cant get my nicely touched up footage open in pp, and have no audio

cheers
