Fade out is not working on AE

[marcello_cruz]

Hi all. Dunno if I have to do something else, but I just wanna do a fade out on the audio. Using After Effects, there is no fade out. I keyframe 10 frames before the end of my comp, with the volume at normal value, then on the latest frame, I put all down the volume. Never has the fade out. So, I start to use the Premire to finish my video and do that. You can see the waveforms to compare when created on AE and on Premiere? There is a way to to this on AE? Using the latest version on both apps. Thanks.

There is a bunch of bugs with this and this could be just such a situation. Since you know your way around Premiere it's the better option, anyway. In any case, do the usual: Reboot your system, clean out any disk caches. Perhaps it will work - for a while at least.

Depending on the frame rate of the comp a 10 frame audio fade may be impossible to detect.

In general in AE you would just animate the layer's audio level.

I did this just yesterday and have not encountered any bugs with this feature.

The only to animate an audio track is creating keyframes e setting the volume. I tried changing the graph too, but is not work. On Premiere or even CapCut a 10 frames is enough to a audiable fade out. Looks it is a problem on the After Effects or maybe is just ignored.

What is the frame rate of the Comp? 

You can check it by going to Composition > Composition Settings.

10 Frames in a Comp that is 24 fps would be a lot longer than 10 frames in a comp that is 120fps.

And I am assuming you are animating the Audio Levels property of audio layer in your Timeline?

[marcello_cruz]

30fps 1080x1920 like on Premiere and CapCut. I tried to start the fade out 60 frames before the end of the comp and is not good too. Fade very early and not smooth. I think the problem is with the AE, not a problem, but maybe a improvement. Yes, using the timeline keyframing the audio level.

Ae has a particular way of fading/leveling audio. True. This is how I always do it:
Set a keframe to 0 dB where I want the fade to start, and then add a keyfram at -48 dB at the end. (Add Easy Ease to the first (0 dB) keyframe if you like that.) Ae's audio leves go down to -192 dB and that number is way to low. -48 dB is low enough to not hear it.
Here is an example of how it would look:

Hi, thanks for the reply. I tried it too before, not setting so down the  audio level, but the problem is that it is not smooth like on Premiere or CapCut. I think it is a problem with AE due Premiere can do this. Here is a pic comparing AE e Premiere with -48. Not smooth....

If you add the fade to white noice you can see the shape better. The in Ae you need to tweak the fade in the Graph editor to be the same. The. You can save it as a preset.

@marcello_cruz , I've created Ae presets (.ffx files) for smooth audio fades. What I did:

1. Generate white noise in Au. Exported a .wav.
2. Imported this in Pr and added the standard 1 second fade to in and out. Exported a .wav
3. Imported both .wav files in Ae and adjusting Keyframe Velocity on the audio level keyframes to mimic the charateristics of Pr fades. Note: I used -70dB as lowest value.
4. Exported the Fade In and Fade Out as presets. Download them here >>

You appear to be facing a problem that many people face with After Effects. Even though the keyframing technique you attempted is viable, the software is designed in such a way that it makes additional editing of audio more difficult than usual; hence, sometimes the fade effect may not act as anticipated. There is an option for using an audio fade workaround like the “Audio Fade” effect or some plugin for this issue but again it’s really not that simple as in Premiere Pro where you just have to drag the wave around for a second and then everything’s fine, right?
First off, I find your decision to switch back to Premiere quite curious. It goes to show how these tools created by Adobe can appear too complex at times even though they are very effective especially when used alone – switching from one tool of this kind to another will not be much help in overcoming such problems either (you cannot cross over from frying pan into fire). However, there are applications such as CapCut that are user-friendly in doing such tasks; they provide simple and quick fading out options which do not require one to manipulate many related factors individually. It is really unfortunate that Adobe has failed to make this process easier in After Effects while CapCut among others have been able to include them perfectly well. Let us hope that Adobe follows suit on these lighter applications and improves its editing of audio so that it becomes less clumsy in upcoming versions!
