    How to make logo / text with animated kerning "smooth"

    mrsigug

      Hello everybody,

       

      I've been doing some After Effects projects for hobby size projects.

      Now Im able to help someone with a movie title for the "big screen" (2K, cinema) and have following problem.

       

      I have a 2k composition in AFX, with 32 bit depth, will export as OpenEXR file sequence.

      The movie title is just 7 letters that should be "kerning" (don't know if it's the correct term)

       

      I have the logo as eps file, have every letter as precomp, and move each letter (except the middle one) with position keyframes at start and end of a 15 second composition. It is black letters on white background.

      When I preview it, it already looks kind of strange and not smooth (motion blur enabled, but animation very slow so no effect anyway) but apparently (Im not at the cinema myself, but get the information from there) it looks even worse on the big screen. "Kind of pixely and stuttery".

       

      Sooo, I searched for the problem. The only thing I found was a "1 px a frame" issue with rolling titles. Having even pixels every frame.

       

      Now... When I use an expression to move the graphic a full even pixel per frame, the whole animation has a specific speed.

      What do I do when it should be animated way slower? It will always have uneven pixels then (0,4 e.g.)?

       

      Is there any other way to solve a problem like this? I understand "full contrast titles" (full black on full white) always makes problems but still.

      On top of everything I put a fast blur of 0,2 which didnt help.

       

      Any help appreciated!

          Yes, it will. you cannot deafeat ther math and even if AE had better antialiasing algorithms, that would not change. that's why most of these kinds of titles have secondary motion like a camera dolly/ zoom or additional effects to cause better distribution of motion blur or distract from potential issues. Often also the outer letters fade in while moving into position. You have to rethink your strategy and come up with something instead of just letting the text come in with animated leading/ spacing.
