So is there anyway to use custom presets on an already created sequence or is the only way you can use your custom presents is when you create a new sequence from your project panel?
Not that I know of - maybe some one else does.
What has worked for me in this situation is to have a 2nd sequence that is set to 4K. I copy the clips I need to stabilize into the 4K sequence, add some handles, do the stabilization, then export the stabilized clip and import that clip back into Pro for use on the 1080p timeline.
