"detailed analysis" on warp stabilizer?

As stated in the manual, Detailed Analysis does extra work to find elements to track. Basically, you should start with the default and if you find that the results aren't as good as you hope, you can try Detailed Analysis as one of your options. This will make your project larger as a lot more data can be stored after the extra analysis, so for performance and efficiency, start with it off.
