    AE - anti-aliasing, flickering in text animation - Advanced control

    masamura

      Hello guys,

      I've a big problem with after effects.

      I'm an advanced user I use ae from 10 years.

      Why in AE there is not  anti-aliasing control as for Nuke or Smoke?

      I'm going crazy!

       

      I usualy work on film titles and  international trailers,

      but often when I make animations the text flickering.

       

      This is a screenshot of the control anti-aliasing on Nuke,

      Is there nothing on AE like that?

      Can anybody help me?


      Thanks

      All the best

          Nope...

          The way to avoid the anti aliasing flicker is to move any file lines an exact number of pixels per frame. It's easy to do with an expression. All you are really doing in Nuke is blurring the edges so the flicker is less noticable.

           

          Here's the expression:

           

          t = time/thisComp.frameDuration;

          x = value[0];

          s = 2;

          y = value[1] - t*s;

          [x, y]

           

          Where 's' is the number of pixels the title will move per frame. Enable motion blur and keep 's' a whole number and the anti aliasing on every frame will be identical.

           

          You still have to watch out for stroboscopic effects like judder that are speed and frame rate dependant, but this will solve your flickering edges.

            Hi Rick,

             

            thanks for the reply!

            But It dosen't work.

             

            I have to make a simple zoom-in of titles

            and your expression is on the y axis

            but even in this case there is always the problem.

             

             

            If it is possible I can send you a test file where you can see the problem.

             

            thanks

              The big problem is stroboscopic effects like judder!

               

              My colleagues use Nuke or Smoke,

              they animate the text and set the antialiasing and the same text is stable, no stroboscopic effect, no flickering ...

              it's easy for them!

              Why?

              I have to go to Nuke?

               

              It is becoming a big problem for me,

              if I don't find a solution, I have to go to Nuke or Smoke,

              but for me it would be a big inconvenience.

               

              Thanks
