Swinging hinge effect for per-character 3d?

[Filip Vandueren]

Sorry, thought I psoetd an answer to this last week,!

Here’s how I solved this, though there’s probably several ways to do it:

• Create a text Layer
• Enable Text->Animate->Per Character 3D
• Add an animator “Rotation”, and set X-rotation to +90° (or-90°, or whatever is the starting rotation)
• Adjust Text->More Options->Grouping Alignment to 0,-100% (this makes the rotation hinge around the top)
• You can delete the Y and Z rotation properties
• Delete the “Range Selector”
• Now add an “Expression Selector“ to the Text Animator
• twirl down the Selector->Amount and paste this expression:
  
  delay=0.06; // amount of seconds between each letter
  swings=1.5; // number of times the text will swing before it's done.

  t=valueAtTime(time-delay*textIndex)[0];

  amt=Math.cos(t*Math.PI*(swings*2)/100)*easeOut(t,0,100,100,0);


• Now to animate the swinging, set keyframes for the amount between [0,0,0] and [100,0,0]
• You can tweak the expression, I think it’s pretty self-explanatory

You can add further properies to the same animator, try for example:
X Rotation=60°
Opacity= 0
Fill Brightness=-80%
Fill Saturation= 40% (if your text is coloured

To get some fake 3D shading

I used another expression you posted to do something similar. Have’nt used this one yet, looking to make the text swing in from above instead of from below. can this be tweaked to solve that?

How would I adapt this to work on an image rather than a text animator?
I know it’s probably something very simple I’m missing – thx!

Great post, it works perfectly!

If it’s just one image, this would work:

If you have more than one image, you could just stagger your layers in time, I think.

Check out More Options > Grouping Alignment.
I adjusted the percentage and problem: solved.

That’s wonderful, I’ve been trying to achieve this the whole day and would have never gotten it without your help!

I owe you a beer or two 🙂

This expression is perfect! How would you go about having the characters flip in a random order rather than from left to right?

delay=0.03; // amount of seconds between each letter
swings=2.0; // number of times the text will swing before it's done

t=valueAtTime(time-delay*textIndex)[0];

amt=Math.cos(t*Math.PI*(swings*2)/100)*easeOut(t,0,100,100,0);

This tweak should do the trick:


delay=0.06; // amount of seconds between each letter
swings=1.5; // number of times the text will swing before it's done.

// randomize the index of the character
// we seed the random generator with timeless=true so that we'll always get
// the same random value per character each time the expression is evaluated.
seedRandom(textIndex,true);
randomIndex=random(textTotal);

t=valueAtTime(time-delay*randomIndex)[0];

amt=Math.cos(t*Math.PI*(swings*2)/100)*easeOut(t,0,100,100,0);


Caveat: It’s not a real “randomise order” the way the range expression does it.
Instead: every character has a random timing. So in theory this could mean very hypothetically, a lot of characters could animate at the same time.
Close enough for rock’n’roll though.

Also, try the same expression on these properties:
Position: 0,300
Scale: 60,160%
Opacity: 0

for a jump up with some stretch and squeeze bounce.
