A bit late in the game but I’m just experiencing this same issue and I’m on AE 2021 (18.2)
In my case, this is has nothing to do with a heavy file/memory/GPU.
I have a fresh new AE file and as I import a specific PNG, a simple 250x250px image, and create a composition with the image inside (250×250 canvas), After Effects does not display the image at specific zoom levels.

What seemed to do the trick for me is changing the colorspace from 8bpc to 16bpc. This may not be ideal if you’re working with specific effects that work better at 8bpc but seems to fix the issue in my case.

Another odd thing that works for me is resizing the composition where this image is by as little as 1px (251×251) the issue stops happening. However if I try to precomp it, and resize the new parent comp back to the original (and wanted) size of 250×250, the problem returns and the image does not show again.

Anyway, these worked for me but it doesn’t entirely fix the issue but at least might workout for you in some cases, I hope it helps anyone else experiencing this.

Sad to see that 5 years on we’re still experiencing frustrating bugs like this.?

Awesome!

Thank you so much Alex

Hey Dan,

I have 2 separate animations, one that triggers when the checkbox is On and another one for when the checkbox is Off.
I’m using your expression to trigger one animation when the checkbox is On, which works perfectly:

n = 0;
p = comp(“Controller”).layer(“Death”).effect(“Player 01”)(“Checkbox”);
if (p.numKeys > 0){
n = p.nearestKey(time).index;
if (p.key(n).time > time) n–;
}
if (n > 0 && p.key(n).value)
time – p.key(n).time
else
0

However, I’m trying to figure out how to get a second animation to trigger when the checkbox is turned OFF.

I’ve tried changing things around in the expression but haven’t been able to figure out what part of the expression is dictating the True/False of the Checkbox.

Any ideas?

Thanks in advance!

Thank you so much Dan,

That should make it.

Oh ok, I think this might do it:

clamp(value, min=-12, max=12)

Thanks anyway!

Hey Cassius,

Thank you so much for your help, it works perfectly.

This is a minor thing but is there a way to constrain the slider min. and max. values?
As in the maximum value the slider goes is either -12 or 12?

Thanks in advance.

Hey Dave,

Thanks for your quick reply.

Having the slider will allow me to link a whole bunch of different layers and different properties to that one single controller without having to keyframe each one of them individually. It speeds up the entire process.

Also, I should rephrase my question as adding increments will just make the size jump every 135px or 120px by sliding the controller.
What I want instead would be for the Size to animate, for example, from 0px to 135px smoothly (will this be achievable by converting the slider units to % ?)

Thanks.

Hey Dan,

Thank you so much for the expression
I’m still on CS6 unfortunately I can’t get the sourceRectAtTime line to work:

L = thisComp.layer(“text”);
r = L.sourceRectAtTime(time,true);
w = r.width*L.scale[0];
h = r.height*L.scale[1];
[w/width,h/height]

Is there an alternative workable on CS6 for that?

[Pedro Amaral]

Actually, is there an expression to have an adjustment layer size to always match a text layer’s bounding box size?

As I have the text precomposed I can use an Adjustment Layer with my effects setup (LinearWipe 01, CC Composite, LinearWipe 02) to do the magic.

Just need to know how to link the dimensions of my Adjustment Layer to the Text Layer dimensions.

Thanks!

Hey Dan,

thanks again for your time and reply.

Indeed the best solution would be a script panel just for typing out, unfortunately I have no scripting knowledge and little time for delivery.

We kind of worked it out by limiting the amount of lines per block of text, meaning we have the precomp with the same size all along and the Linear Wipe doesn’t look so bad.

Cheers
