I got my answer from another forum. It turns out that I had ‘All frames’ activated in the timeline, which was prohibiting me from playing the audio realtime. Once I deactivated ‘All frames’ it played fine.

If you want to read the forum thread from https://www.c4dcafe.com, I included it below.

I’m afraid not. He’ll have to upgrade.

All the best,

1.Go ahead and time remap the glass layer and the ‘precomp holding the footage’ until it suits you.

2.Duplicate the ‘precomp that is holding the footage’.

3.Delete the time remapping on the duplicate layer.

4.Presuming the original ‘precomp holding the footage’ is called layer “x”, apply the following expressions to the duplicate layer:

To position:

L=thisComp.layer(“x”);
L.toWorld(L.anchorPoint)

To orientation:

C = thisComp.layer(“x”);
u = C.toWorldVec([1,0,0]);
v = C.toWorldVec([0,1,0]);
w = C.toWorldVec([0,0,1]);

sinb = clamp(w[0],-1,1);
b = Math.asin(sinb);
cosb = Math.cos(b);
if (Math.abs(cosb) > .0005){
c = -Math.atan2(v[0],u[0]);
a = -Math.atan2(w[1],w[2]);
}else{
a = Math.atan2(u[1],v[1]);
c = 0;
}
[radiansToDegrees(a),radiansToDegrees(b),radiansToDegrees(c)]

5.After the expressions are applied, turn off the eyeball and sound for the original ‘precomp that is holding the footage’ layer. Its only function is to feed coordinate data to the duplicate layer holding your properly timed footage.

These expressions are thanks to Dan Ebberts. I picked them up from following posts relating to .toWorld expressions. If you’re wondering, the orientation expression is necessary to solve the discrepancy in the motion path caused from the combined axes of the X,Y,&Z rotation parameters moving in unison. Hope that makes sense. If not, the following posts should clear things up.

Let me know if these expressions help.

So, tell me if I understand you correctly. The rotating glass and the precomp holding the footage needs to be retimed, but the footage still needs to run at its proper speed? Is that right?

Hey Thanks! More than one way to achieve it! That is easier! I appreciate it!
Oh, and you’re right. Divide by 1 will return 1. I spoke too soon on that one.

Thanks for your help!

y=thisComp.layer("AE solid").position[1]-thisComp.height/2;
y/-1

I found the answer to my own question on an earlier post! I guess I just wasn’t putting in the right key words for the search the first time I tried.

The answer was pretty simple. Just divide the value by -1 (positive 1 depending on which way you want to go).

Hope this helps anyone else in the same predicament.

Thanks!

Try this expression:

smooth(width=.5, samples=25, t=time)

apply it to your position property or to whatever property you’re using to animate by keyframing.

If the motion’s still not quite right, try raising or lowering the width parameter. Something like .75 or .25.

I found this solution on the COW some time ago and its worked great!

Great! I’ll do just that! I love the COW! Thanks for all of your help!

Thanks for the quick responses! This is just the kind of confirmation I need. Question though regarding ‘one-pass compression’. I’m using the Quicktime export function under the file menu in FCP to do the compressing. Is this function using one-pass compression, or should I look to another means of export to ensure the least information loss possible?

Oh, and there are no transitions or other effects involved in these exports. So that shouldn’t be a problem.

Thanks so much for your help!

I captured DV25 footage using the DV NTSC preset with an AJA Kona LSe
and I plan to export using DV NTSC.

What’d you think?
