Okay got you, thanks. It seems to work great, just need to tweak the values. Is it possible to save code snippets like these under Effects & Presets for easier access?

[Magnus Hellmen]

Nice one, I figured it must be something like that! My solution was to place each audio clip in its own comp first.

Another interesting thing I noticed.
– I make a pre-comp containing my audio file and the key frame layer I’ve created.
– I then reference the key frame slider in a solid located in the parent comp, ie on the “outside” if you will.

If I now move this audio/keyframe comp on the parent comp timeline then only the audio part moves in time. They keyframes stay. So if for example I’m animating a mouth but I don’t like the timing so I move the audio/keyframe comp forward on the time line, only the audio moves. So I now have a mouth blinking way ahead of the sound.

If I create the exact same setup except, the mouth solid is located inside the same comp as the keyframe layer and audio, I can move this entire package on the parent comp timeline and the mouth graphic + audio will move in time together and remain in sync.

Thanks guys,

Dan how would I go about implementing your code in James script?

[Magnus Hellmen]

It should only wiggle along the Y-axis regardless of what the layer movement is. When it wiggles on the x-axis it sometimes looks as if the character is jumping back but moving forward.

It’s AE CC 2017. All I did was expand the waveforms and screen capture that part of the timeline. If you expand the graph editor and select both audio tracks and the track with keyframes you can see the wave forms under the keyframe graph.

Interestingly, I can also choose convert audio to keyframes without having any track selected, and that gives me the exact same result. I don’t seem to be able to specify which waveform I want to target.

The script works great, thanks. I’ve been trying to modify it to only affect the Y-axis but I can’t do it.

[Magnus Hellmen]

Thanks, here’s what I don’t understand. I created a comp and imported two audio clips. I placed them in the comp as you can see.

I then selected track1.wav and chose convert audio to keyframes.

The resulting keyframes cover both audio clips. If I had a 10 minute comp with 100 audio clips I would get an unworkable amount of keyframes after I run this operation.

Is this a feature of AE or am I doing something wrong?

[Magnus Hellmen]

Thanks for replying. If I convert to keyframes on each audio track then I have 2 Audio Amplitude tracks with the exact same keyframe information. Are you saying to then delete the keyframes that aren’t applicable to that dialogue? I connect these keyframes to the opacity of the character mouth layer and both characters would talk identically otherwise.

[Magnus Hellmen]

Many thanks for the reply, I’ll make an attempt and see if I can get it working.

[Magnus Hellmen]

Great, thanks. For now I’ve solved it simply by connecting the open_mouth image opacity value to the keyframe slider created from the audio waveform. That way it blinks in sync with the dialogue which look pixel-tacky enough for my purposes.
