Effects Stop working at exactly 22 seconds

[samtgarner]

I really hope someone can help me with this. I'm putting together ananimation and I'm applying a hand-drawn effect to the linework. I'm doing this on an adjustment layer above all the layers I want to change. At exactly 22 seconds (I've tried it on a few Comps), the effect stops working and just freezes, Has anyone else had this issue and fixed it?

Hi samtgarner,

Thanks for reaching out. We've got your back.

It sounds like an issue with a media or an effect applied to a layer. To find out that layer, try turning the layers off one by and see if still freezes when you go to 22 seconds. If that doesn't work, try importing this project into a new one and see if that brings any change.

Let us know how it goes.

Thanks,

Nishu

It was how the effect was working. I had put a time expression to a turbulent displace effect on the adjustment layer to create a hand drawn effect effect, I found if I moved that expression to the random seed rather than the evolution it fixed the issue.

Thanks!

I had the same problem with that effect and this fixed it!

Jeez.  Can't believe I found this, but it fixed my issue as well.  Thank you!

Glad you found a fix!

I've logged in just to say thank you for this! I was stressing and pulling hair outs because it wouldn't work and my assignment deadline is drawing near. You saved me!

this doesn't entirely fix the issue, the rough edges don't look the same as the ones before 22 second

[samtgarner]

Did you take the expression off the original evolution. You only need 1

[flakecase]

I don't quite understand what is meant by "moving that expression to the random seed rather than the evolution."

Under Evolution Options I have:

• Cycle Evolution in the OFF position

• Cycle (in Revolutions) is greyed out set at 59—so that can't ne adjusted.

• Random Seed is set at 0

But no matter what setting Random Seed is set to, all movement still ceases at 22 seconds. WTF!?

Damn! I would pay u a beer bro! You changed my life forever with that tip! Thanks so much!!

This is the best video for this issue: https://youtu.be/AEMuhZINkaY?si=s8pWOn6wf9XTWoh1

This is the right answer. "Exactly at 22 seconds" might be different from user to user depending on exactly what your expression is. The real limitation is ± 91 rotations and 8 degrees, or a ± 32768 total degrees. This is due to a limitation of the data type used to store the value of the evolution property (15 bits for absolute value and 1 bit for ± sign).

Now that you know that, work around that in the way that's best for you. You could use this to make the value "wrap" back to 0 once it goes beyond 32768, which will probably work as expected for most cases:

value % 32768

Also, this is a bug in After Effects. Requiring users to modulo their values by a power of 2 is leaking implementation details (which could change later). The wrapping should be built in.
