Transfer Photoshop animation timeline screenshots into After Effects?

I was wondering if anyone has any ideas on how I could best transfer a Photoshop video timeline with screenShots to after effects. I was creating a gif then it became a huge production of 301 screenshots and over 600 layers lol. I really love the video and I know it will be easier to finish it in after effects. The only thing I can think of to do is to to convert layers that create individual moving objects into video files on separate photoshop projects then transfer them individually into after effects. This is a difficult process so if anyone by chance has any better ideas to smoothly transition this photoshop video into after effects it would be much appreciated.
