Grainy Preview

Hey all,

 

I have a decent understanding of after effects but mainly use it to create timelapse. Over the past 6 months I have probably put through over 200 timelapse sequences so I'm kind of stumped as to why I'm having this problem all of a sudden. I have a raw image sequence that I am trying to bring in and the preview is extremely grainy. It almost looks like the grain of the image(I did shoot at 800 iso) is being amplified quite a bit. Not sure why this is happening but some brief research led me to believe it might be an opencl issue with my laptop.  The cr2, rendered jpegs from lightroom, and final video seem to be ok but if I want to denoise any of my footage in after effects I have no idea of knowing how much to put on there and would like to rectify for future projects.

I have tried importing as 32 bit, and a few other things but I've never really seen this before. Even when the ACR screen comes up on import it all looks dandy so I'm not sure what could be going on.
