Like I said, doing a quick fade out, or doing a quick edit in music with a crossfade, just to see if it’s better to animate like that, without having to go to another program.

It’s simply impossible to do a fade out or crossfade using two keyframes. Okay, I can export to protools or Logic Audio, (both certainly not faster If i’ve allready got the audio two layers ready in my comp) And what If I decide the first layers one should be 20 frames longer, back to pro-tools etc.

Of course, the final mixing I would do in another app.

But mainly, because I like to code useless expressions 😉

You should check out the 7.1 surround export expression i created for correct placement of sound emitted from 3D layers in After Effects space, including Doppler simulation 😉

No, really.

If you open up the footage in a layer-viewer (double click it in the timeline),
you can drag around the anchorPoint with the move tool (if it’s visible).

Now holding down the Command+Shift keys (Ctrl+shift on PC i guess) while doing this,
the anchorPoint will snap to the center of the footage, to a corner or anywhere along the edge.

This behaviour is not available in the Comp viewer using the Pan-behind tool.

A while ago I wrote a script called BPMMarkers that adds markers for each beat on a layer (you have to know the bpm though)

check out the discussion here to download the file and get some more tips on working with audio:

As for absolute precision with keyframes and markers, I tend to switch to 50 or even 99 fps from time to time to do audio-scrubbing.

Hi Dan,

I can’t test this for the moment,
but would this expression sum up all the rotations for e.g.
a camera that is Auto-oriented + keyframed for rotation + keyframed for orientation ?

if so: brilliant stuff, just what I needed for a problem I was working on 😎

on a related note: do you think it is feasible in Javascript to convert an After Effects style 3D Euler rotation to a VRML-style axis+angle rotation ?

One could use the noise() function for “a global random fixed number”.

just feed the seed as it’s only parameter. noise(seed), noise([seed,seed]) or even noise([seed,seed,seed])

Granted, this is not a true “seed”-value, rather the “position” in a “noise-field”,
and also not a true random number, (e.g. noise(100) and noise(101) will most likely have similar results)
but it’s a start

just choose either “seed”-values that aren’t too closely spaced, or multiply them by a quite large prime number.
