Class 11 - Riders & TSM

I had to refine a background plate for the shot about Joyrider today. However, I am experiencing extreme issues with Nuke. I have gone through a tremendous amount of crashing throughout compositing, and more importantly - rendering WIP videos. I am not 100% sure where the issue is coming from, but I think it may have to do with a camera shake gizmo. I tried deleting this gizmo, as well as condensing/optimizing the node tree. Yet, I am still crashing, and can;t produce final frames for this high-speed shot. I am going to run through my issues with Drew next class, and hopefully we can fix the issues. For now, here is a WIP render:

For The Space Messenger, I have started keying this shot: This has proved itself as very challenging so far.
