Hey y'all, I'm really stuck.

 

This error keeps popping up for me and I have no idea how to solve it. It'll appear as I'm trying to play a sequence with an image in it. I made other sequences with images in them a few hours ago and rhey're all fine. But now when tryong to add anything new, it gives me this error and doesn't go away at all - no matter how many times I hit 'okay'. Any ideas?

 

Thanks!

The issue is coming from using the Cinema 4D renderer. If you can switch back to Classic 3D that will resolve the issue. Or install 23.5 or the 24.1 Beta where the issue doesn't exist/is fixed. It will also be fixed in 24.0 when that is released in a few weeks from now.

You can definitely install older versions of AE via the Creative Cloud Desktop app.

 

23.6 does have a bug around this error with the Cinema 4D renderer. It will be fixed in the 24.0 release coming soonish.

After Effects 23.6

Mac 13.5.2

I keep getting an error that says After Effects error: zero denominator comparing ratios (17 :: 16). The app freezes and I have to force quit to get out of it. It seems to happen when pressing the space bar to play. I have an audio file in the project. I copy and use the same file every month and have not had a problem in the past.

But what do you do when you are animating in 3D because you need the cinema 4D renderer on to extrude the shape?

I work with your latest version of After Effects (23.6) and I'm encountering this annoying bug. Sometimes when I press "space" (play) a window with the text: After effects error: zero denominator comparing ratios ( 17 :: 16 ) (see attachment) pops up. As said, sometimes it pops up, sometimes don't. It feels that this occurrs at random.

First I thought it happened because I worked with a large .psd file within AE, but then it happened also when I worked with a much simpler FullHD comp with only text layers. To get rid of the window I have to press the "OK" button from anywhere between 5-20 times, which is very annoying.

The only way for me to watch through my timeline is to use the numpad space (0) instead of the space bar, which notably slows down my work.

 

I work with:

Processor AMD Ryzen 9 3900X 12-Core Processor 3.79 GHz
Installed RAM 16,0 GB
System type 64-bit operating system, x64-based processor

Edition Windows 10 Home
Version 22H2

 

Hope you could find a solution to the annoyance!

Thanks for the report. There is a fix in 24.1 beta builds and a fix will be in 24.0 when it releases in a few weeks from now. If you don't need to use the Cinema 4D renderer, switching to Classic 3D should also resolve this issue.

Over a month and still no fix, not being able to play video in video editing/compositing software makes it pretty much useless. What am I even paying for every month?

Once this is patched, I'm going to stop updating my software, because Adobe cannot be trusted to support their own products, and couldn't care less when they break them, which happens every single version.

The only reason Adobe still exist is because they've cornered the market and created a pseudo-monopoly, the company itself is run like absolute garbage and couldn't care less about their user base.

Obviously it's not ideal but you can downgrade/roll-back to the previous version 23.5.
In the Creative Cloud app choose "All Apps"

@Clubhouse There is a fix in the Beta builds if you want to use that. Otherwise, yes, we have not released 24.0 yet (just a couple of weeks) which also has the fix in it. Or return to 23.5. Or if you can use Classic 3D renderer, use that. We are sorry for the issue.

I and my colleagues are getting this error in projects without any 3D layers at all, so for us, the 3D render engine is not the issue.

@Jeffrey3113140136mh even without 3D layers in the comp, your render engine may still be Cinema 4D. Please check if that's the case. Comp Settings -> 3D Renderer.

I had this issue and solved it by going back to Classic 3D (in composition settings>3D Renderer).

I had some compositions that use cinema 4D. Those I had to replace with an exported version with alpha.

I changed to the Classic 3D renderer, but this issue persists for me.  People keep posting that as a solution, but it is not working for many of us.

Yes, this is a known bug. Your options:

1. Roll back to 23.5

2. Install AE 24.1 Beta where it is fixed

3. Wait for 24.0 to be released (next week) where it is also fixed

4. Switch your renderer back to Classic 3D, off of Cinema 4D. I know you don't have 3D layers, but the renderer is still selected in the Composition Settings.

Exact same problem. MY FIX:

I found that when I hit the spacebar to preview / play my work, this error came up if I had any tracks selected.

It happened consistently - had to hit the button 50 times to get it to go away.

So I am now sure to deselect any tracks before hitting the spacebar.

This works for me consistently.

Hi, I'm having the same issue. 
Initially, I was swapping back to Classic 3D renderer so I could preview my scene. This worked for a while and I was able to switch to C4D Render to tweak things and switch back to Classic 3D to preview things. 

Now however, it's giving me the error on Classic 3D renderer as well as C4D and it suckkss. 
I'm on AE v23.6. Any idea when 24.0 is coming out?
