If you are tryinig to rotoscope the entire lady in the picture... then, you will need a LOT of time, patience and LUCK.
You will have to make a choice between saving the hair or dropping the background out. If it was me... I would sacrifice the hair... as for the blur, that is a BIG problem and there is no simple solution (... if any solution)... specially when you look at the foreground plants in the video.
If there is any way to reshoot... then, that would definately be the best option. If not, then prepare for a LOOONG and painful rotoscoping project.... and, in the end... I doubt it will look good.
Joe is right, you'd better settle in for a long roto session.
There are some things you can do for the hair, and if you're lucky it will get rid of some of the foliage. Try to build up some procedural mattes first, to limit the amount of stuff you'll have to roto. It's still not going to be a simple task. It will probably help you keep in more hair detail.
If you are doing this sort of roto, I would highly recommend using Mocha or Mocha AE & mochaShape to take some of the pain out of it. The big boy version of mocha lets you deal a lot better with the motion blur. I go through lots of techniques in my paint & roto course Cut and Shut.
Good luck in your project. Some good quality coffee will make the whole thing a better experience!
