It’s ok I understand, there’s to many variations now in these outer layers to work out.
I wonder if one expression could cover all of the layers and somehow take in to account all the rotations and all the widths at once. . . .
Sorry I realise that’s a ridiculous amount of calculations. . I’ll try and hack something out of what I have already.
Thanks
Richie.

Thanks Dan.
Your expression is in the main comp, placed on the central layer and has completely stabilised the adjoining two layers, it’s worked really well, better for some reason than it has in the test project, I’m now tackling the outer layers.
What I’d planned on doing was disabling the scale of the next adjoining layer using your previous “Disable scale from parent” expression.
L = thisLayer;
s = transform.scale.value;
while (L.hasParent){
L = L.parent;
for (i = 0; i < s.length; i++) s[i] *= 100/L.transform.scale.value[i] } s This has worked fine, this layer now acts the same as the original centre layer in the first test project, so I was hoping to be able to repeat your "yrotation scaling" expression again on the next layer (left most layer, layer 1) but it's not working the same as it it did for the centre layers, I can't figure out why this is, I know the camera position has effected the perspective a little, the outer layer may also still be scaling through it's parenting possibly but only very slightly if at all, for some reason it's rotation is very slightly out and the expression isn't stabilizing the shape width as before. I've updated the project and entered the expressions (to layer 1 and 2) as I think they should be, would you have a look over them for me perhaps? 412_yrotationscaleproject2.aep.zipThe only thing I’ve changed in the expression is that now the centre layer is twice it’s width this is so as to plaice the anchor point back to centre from the point of view of the expression.
Could you have a look?
Regards
Richie.

What genre is it? murder mystery, film noire, Buddy cop?
Who are your influences, and do you have to use stills?

Dan, that works beautifully!! absolutely amazing!! I’m so grateful, every time I’ve come up against a problem you’ve absolutely demolished it!! lol, I’m completely in awe of you 🙂
I tested it in the example project and it’s easly precise enough for what I need to do, I’ll perhaps have to ask you a few questions after I’ve dropped it in to the main comp, which I’m doing now.
I did also wan’t to know what are the variables in this expression that I will need to tweak, obviously there are the layer names, that’s no problem, but the layer widths also?
mw = 470; // width of middle layer
w = 430; // width of this layerAnything other than these?
By the way, in the test comp the expression works fine when yrotations pass 90 and even – 90, marvellous work!!
Thanks again.

Sounds very complicated, thanks for taking the time to explain but that’s way beyond me, I could probably get some help with the maths possibly, but can AF handle these kinds of equations as expressions?
In all honesty, I’d be happy if the shape even stayed roughly the same width as the comp window, at the moment my comp doesn’t, it expands way out of bounds and then shrinks to a great deal smaller then comp width, what I’m wondering is if you had an ideal project to work on and you knew the missing values that you needed to know to work out this expression could you put together something that roughly worked?
I feel I’m asking to much of you here actually, though it perhaps doesn’t need to be as precise as your thinking, if you can find the time to put something rough my way at some stage I’d be very grateful and happy to experiment with it till it worked well enough.
There is a camera in the comp, it’s a shy layer, the width of the layers I think I can re adjust and provide you with in an updated project this evening (including) an exact pixel count of the width of each layer if that would help?
Let me know what you think, I realise it’s maybe going to be too time consuming for you which is perfectly understandable.

The Digi effects packs are very close to this, there’s an effects called Bad codec which might be what you want, you might also be interested in “Bad TV” and Blockade.
I’d recommend all of their effects, they’re absolutely awesome, you may want to spend quite a bit of time browsing what they have, though I can’t find exactly what your looking for (heavy image buffering effect) these are all similar. .

Open GL? do you have it on or off? What other background tasks do you have running? Have you removed all the unnecessary tat that boot’s on your system at startup?
EDD: just checked MSconfig there’s virtually nothing booting at startup, 1 chipset driver and my ATI catalyst that’s all, (though this is not advised) I don’t use any security features, I manually scan for viruses regularly instead.

Or, I would say maybe your operating system has gotten damaged perhaps, could also be a loose stick of ram maybe, you should also re-install AFX, I have no such problems on CS3 here, if you want to do some comparisons I’d be more than happy to load up a similar project on to my system and time the ram previews.
I’m running an i7 3.07 Ghz processor, that gives me 8 threads, 12 gig of ddr3 ram, two HD 4870 Graphics cards and XP pro 64.
The settings I use are straight forward enough, I have 24 gig on the page file, cache folders are left at their defaults, the memory and system preferences are maximum memory usage – %100 maximum ram cache size %60.
I work on 1080p projects with my comp window set to %50 size and resolution, the ram previews are very fast with MP enabled the preview loads at about twice the playback speed, with MP off the previews load at around. just over normal playback speed.
The only other suggestions I can think of would be to watch out which plugins and scripts your using, I use throttle, but I’ve had bad experiences with plugins like nucleo pro, and if your working with 3D based plugins then you’d expect the processing time to increase by a large amount (obviously).

Success!!!
Thank you Dan, I should be able to keep this shot within the comp bounds now whilst it’s deforming, it’s a lot of juggling around with some of the layers being delayed to scale at different times, but I think it’s going to look insane, I also got past my 3D warps problem so in addition to the collapsing of the layers, they can also be warped in to additional 3d shapes, crazy 🙂
Thanks Dan, I envy your talents 😉

Hi Dan, thanks for the help.
No luck this end I’m afraid, the layer still scales smaller and larger, I wonder if it might have something to do with how many children are stacked above it, I don’t know. .
I found an expression of yours for the same thing only excludes rotation, but I couldn’t adapt it to work for scale.
value – parent.transform.rotation
maybe this will offer a clue?

I wonder if you’re maxing out your page file?
Your page file should be set to 3 times the overall amount of ram you have installed, my page file usage tends to hover around 10 gig, this might not be what’s going wrong for you but I think it’s commonly overlooked.
