Final cut to After effects - Render Glitch

Hey guys,

I'm using a script called FCPtoAE in order to send a final cut video to after effects for color correction etc.

I tried rendering the comp I made in ae and when I play back the exported footage it glitches/freezes during playback. The timeline continues to play but the video freezes.

My render settings are as follows:

Render Settings: Current Settings

Output: Lossless

I've even tried exporting the video directly from FCP and adding it to AE then setting it to render and I have the same issue either way...

Does anyone know what the fix is for this?
