    Problem when pre-composing masked layer


      Ok, i am having a problem when masking a Twixtored layer.


      this is what happens:



      i have the original footage in a comp, i used twixtor to slow it down to 3% speed


      Seen here: http://prntscr.com/zbicc


      I Then pre composed that slowed down layer into a comp of it's own and masked around that parts i wanted and named this comp "masked comp 1"


      Seen here: http://prntscr.com/zbitw

      and here: http://prntscr.com/zbiyc


      i then precomposed the masked layer into another comp called "sky replacement" and this is when i hit the problem, it dosn't show up, it just gives me a black screen.

      I tried rendering out "Masked comp 1" and "sky replacement" and with both it just renders a black screen, but if i render the Twixtored comp that renders fine. So i think it has somthing to do with the mask but i can't figure it out.


      Please help.

          The black screen notwithstanding, I see two VERY big problems in the workflow as described... or at least as how I understand your workflow.


          You used Twixtor to slow down video to 3% of its normal speed:  that represents tons and tons of speed redeuction, and you're lucky that Twixtor was able to give you a useful image AT ALL.  Then you precomped it, too boot.


          Then you hoped against all hope that you could effectively mask the precomp... which was presumably at the target frame rate.


          Give yourself a fighting chance to come up with something:  once you use Twxtor, prerender it.  And I have to tell you: if you are actually using Twixtor to slow down footage to 3% of normal speed, it probably won't look good.  Twixtor is great for minor speed variations, but for 3% of normal?  It can't work miracles......
