warp stabilizer slow

I dont know why, Ive edited videos daily and warp stabilzer is taking 60+mins on a few clips. 

Now i know im being veru braud, and my system im editing on isnt the issue. Im just wondering if there was anything in the last update that wouod cause this or something i can look into that can fix this. 

Honestly no clue why this is happing it never take no more then 30 seconds on this computer
