    Rotoscoping vs Green Screen

    smitpr1

      With the new advancements for roto in CS5 does anyone see this as a practical way to replace doing green screen?  Has anyone tried doing roto from this point of view?  The subjects that I would be filming would basically be giving lectures, not a lot of movement.  Does anyone have any experience in this area?

          Not really a good idea. Assumed you're working with a GOOD green screen you shouldn't have much problems with hair, fingers, and so on. You won't be able to do a good hair-mask with the rotobrush.

           

          But ok - if the lecturers are all bald guys...it should work!

            Agreed!  The rotobrush is a fantastic tool for the toolbox, and can be a helpful addition to greenscreen work as well, but there's a reason why so much stuff in Hollywood is still shot on greenscreen: it really works.

             

            Obviously, there are times when roto is preferable to greenscreen - when you need resolution independence from masks etc.  But typically, and if shot properly, greensceen is by far the most efficient way to composite.

              The Roto Brush could be considered a kitchen knife, Green Screen (keying) a scalpel. If your footage is highly compressed and low resolution, like DV footage for example, the Roto Brush is more like an axe and green screen is more like a kitchen knife.

               

              If you want to do really good cosmetic surgery then you need high quality footage and a really sharp scalpel.

               

              Roto, even with the Roto Brush is a tedious and slow process. It is best used to separate a subject from the background so you can put something between the subject and the background. If you want to replace the background then rotoscoping would be the tool of last resort.
