Slider control effect not rendering. Help !

Report · Jan 03, 2019

Hello !

I made an animation of some illustration I made and I used the slider controls to make a butterfly flap.

the butterfly is in a 3D layer with two slider control effects on a Null object ( one named speed and the other flap ), flap slider with the expression: Math.sin(time*effect("Speed")("Slider"))*45

everything is fine when I preview in After Effect BUT after rendering in Adobe Media Encoder (H.264, Youtube 1080p), the flapping of the butterfly is no longer visible.

i'm in an active camera, comp is classical 3D, no camera layer

here's videos to illustrate my problem:

slider effect in the butterfly comp ( butterfly flapping 😞 butterfly flapping - 3D layers + slider controls - YouTube

How it looks on the final comp when previewed in AE ( butterfly still flapping 😞 butterfly flapping - final comp preview - YouTube

how it looks after being rendered in AME ( no more flapping 😞 After rendering in Adobe Media Encoder - butterfly not flapping ! - YouTube

Thanks !

What happens if you render it using AE's render queue into something like DNxHD? You could then throw that file into AME to get your MP4.

Hey Szalam,

What timing!

Hi laurag,

Lovely little animation - I really like it!

Thanks for your detailed post.

If the problem is rendering via Adobe Media Encoder, have you tried rendering via the After Effects Render Queue?

I know that means no H.264 but you can try any other format as a test.

Let us know how it goes.

Best,

Rameez

Hey Rameer,

( I'm glad you liked the animation ^_^ )

the exact same thing happens when I render in AE's render queue .... no flapping.

I don't know what to try anymore !!

thanks for your comment.

If you show us screenshots of the entire UI with the Comp selected in the Project panel so we can see the comp settings and the layers that are giving you problems selected in the timeline showing their modified properties (press uu) we can probably help you figure it out. This sounds like more like a workflow issue than a bug to me, but unless you can share the comp or screenshots the problem is going to be very hard to figure out.

this is the composition and all the modified properties, it is supposed to be in a major composition but even rendering it like a single comp the slider in Media Encoder doesn't work, please help me thank you it's an important work

tunot87909670, I reproduced your screenshot.

The expression in source text successfully reads the slider control, limits the decimal places to 2, and adds %.

The expression added to the slider control does nothing at all, it just retrieves the value of the slider. It is unnecessary and should be removed.

There are 2 keyframes for the slider, 100 and something else so the number should change unless the value of the slider is the same in both keyframes.

There is one keyframe for Layer/Transform/Scale so nothing changes there.

The layer is visible for about 15 frames. What is happening on that layer in the comp that is not rendering? Absolutely the only thing that I see that could possibly cause this layer not to animate is equal values for the slider keyframes or some completely weird bug in the expression you have added to the slider that is not doing anything.

still not working i don't know what to do.

there is another way to do a transition from 100 to 0.08%?

tunot87909670, Try this.

Create a new comp.
Add an empty text layer.
Add an Expression control slider to the text layer to the text layer
Add this expression to Source Text

effect("Slider Control")("Slider").value.toFixed(2) + "%"

Set a keyframe with a slider value of 100
Move down the timeline about one second and set the slider value to .08
Send this comp to the Media Encoder and render it

If that works copy the layer and paste it in the comp that is not working and delete the original layer.
