Hi Sam, it’ll give a blank frame for a precomp, but not for footage.

Groetjes uit Diest 🙂

D’oh,

I meant:

source.duration-source.frameDuration;

alhough just source.duration; will probably work too because time remap should take care of showing the last frame even if the number is too high.

So in theory even this works too:

Number.MAX_VALUE;

[Filip Vandueren]

Not sure, but maybe source.length – source.frameDuration ?

If (and that’s an important if) the camera is already positioned exactly on top/in front of your layer and it only needs to zoom in:

l=thisComp.layer("White Solid 1");
d=length(
	thisLayer.toWorld([0,0,0]),
	l.toWorld(l.anchorPoint)
);
w = length(l.toWorld([0,0]),l.toWorld([l.width,0]));
zoom = (thisComp.width/w) * d;

I think I chucked enough toWorld()’s in there to make sure that parented camera’s and layer and scaled layers etc. should also work, but you might maybe still run into certain edge cases.

Hi Tim,

can’t replicate the problem.

The start plays back in nearly realtime 9~15 ms per frame at full res on my Macbook.

But the longer the comp is, the slower it gets. For example after 2 minutes, about 130ms per frame

Like I said, expressions nor scripting can alter the styling of parts of a text-layer. You can only style the entire layer, not a word or selection within it.

There exist solutions of marking a [part of your text] with characters like those square brackets, then hide them but use their indexes to create animation ranges, which can do limited things like change the color, add a stroke, slant,… but not actually change font properties like in the character styling.

It’s a question that gets asked quite often on the forum, unfortunately the search seems broken now, so I can’t point you to a solution right now.

[Filip Vandueren]

There is no way to style a section of your text using expressions.

The only work arounds are using text animators that control the stroke width of a range of characters (emulating faux bold, but without the increased tracking) or provide a slant to some characters (faux italic/oblique)

How would the expression know what word to highlight ? Does it use RTF ? or HTML tags ?

[Filip Vandueren]

I think this is because you have an alpha channel and I had a black solid BG.

[Filip Vandueren]

Yes; start your expression with the line:

posterizeTime(0);

It doesn’t prevent the property/expression from recalculating when something changes in the comp while working, but it does only calculate once when you render or ram preview

Hi Ryan,

I don’t know anything about engines, so I probably used some wrong terminology, but see the project in attachment.

Things you can adjust:

– the length of the shaft

– the orientation of the head (45 / -45, or any other rotation)

– the point where the shaft is connected to the inner circle (axis ?) which I called the “bolt”
