usually green footage is an indicator that you don’t have the codec that is needed to decode the footage… which seems strange in this case since i assume the that you have premiere and ae on the same machine, and if premiere can use the footage, then you would assume that ae could too.
however, that may not be the case. i remember when adobe first added support for dvcprohd in mxf format. they did that first in premiere, then later in ae.
you could export a clip from premiere to another codec (i would go with qt lossless animation to preserve quality). take the export into ae for effecting, and render back to qt lossless animation. bring that into premiere and replace the previously exported clip with the new render.
another option would be to find another codec to use in premiere that ae will also read, then use dynamic link to go between premiere and after effects. if you are mid-project, this probably isn’t what you want to do, but you might do some experimentation for future projects.
