Working between Premier and After Effects P1

There are a few ways in which you can do this, toy an put your Premiere Peo footage into After Effect by simple highlighting the images and clicking 'File' - 'Export' - 'Media' then select the right format that you need and then simply click export. 

When you want to put the clips into After effects you have to highlight all the clips then right click and click replace with 'After effects composition'

The final way in which you can transfer the footage from Premier to After Effects is to select all of the clips by selecting first one, holding down Shift and then selecting the last one. You then need to hold and drag the clips holding down alt which will then duplicate the footage to wherever you are taking it to. This will then duplicate the full sequence into After Effects.
