After Effects error: zero denominator in ratio addition 17::16

Sagesb17 Aug 1, 2017 2:39 PM

I'm still a noob when it comes to After Effects, and I have looked everywhere on how to fix this issue. My last resort was asking on here. I don't know what information is needed to figure out the problem, so I'll explain what I can. I have windows 10. This stupid error only started popping up since yesterday, when I tried going onto graph editor to view the speed graph. On both the value and speed graph, the keyframes weren't visible. The one time they were, I only managed to modify one before After Effects crashed. I tried again a few more times, and got the same result. This isn't a problem with importing a composition, just editing the graph. Restarting or uninstalling and reinstalling has not helped. Has anyone else experienced this error? Because for some reason there's no trace of it, where I've looked. This is really frustrating and I want to fix it soon. Please help! Here's a screenshot of the popup I get:

This error can have al lsorts of causes and without better info nobody can really tell you where it is coming from. It's an internal math error, obviously, and can affect anything from decoding the footage to specific functions and effects. Based on your screenshot the only thing thatr comes to mind is trying to re-encode/ transcode your source file in case its streams are damaged. this may avoid the issue then...

No, unfortunately not. The other day it was working just fine, but I tried again today and the same issue occurred. I just do this for a hobby and have had no training, so I don't know how to re-code/transcode a source file like the other user suggested. Do you know how I can fix this? Thank you!

I'd really appreciate it if I got some help, I've also been getting a (27::15) error and it's really frustrating, sometimes AE will crash. I don't want to be paying for a software with some features unaccessible .

Hi sagesb,
Did you do as recommended and transcode your file? You can do so in Media Encoder. Here's some basic steps: https://filmpost.co/2016/09/a-beginners-guide-to-transcoding-with-adobe-media-encoder/

Let us know if you have questions.

Thanks,
Kevin

The last two posters, Sagesb17 and aerinp2268496, have provided precisely ZERO information to help with a diagnosis. They're just whining. So based on the wealth of information they provided, here's my response;

After Effects doesn't like you any more. You dd something to make it angry. You have to atone. I suggest buying it flowers and taking it out to a really nice restaurant for a fine candlelight dinner.

Hey, it's just as good a recommendation as anything else.
