Resolution lose in composition works

[Mylenium]

Hi all!

Big problem you may solve easily. Well I have High res images in comp01. Really High res images I can zoom in. In comp02 I zoom in comp01, but the high res images are ugly smoothed and not much detailed. It seems Comp01 is locked in resolution, even thoug the images in are high res.

> How to let after effects understand that when I zoom on something, it should take advantage of the footage real resoltion, not the containing comp resolution ?

URGENT, thank you really much all :thumbsup:

What you are experiencing has to do with the way AE renders its stuff - it will apply interpolation to any transformation and effect, even if it's just a simple change in position (because it bases its calculations on sub-pixel precision). Multiple passes will add up because the oversampling assigns new values for each change. You can, however remedy this by using the collapse transformations/ continuous rasterize switch on your sub-comp. This will force AE to only calculate all transformations once and apply its interpolation.

This option function is like the concatenation found in others softwares like Fusion?

Yes, in a way. Though it has some disadvantages as well (since the continuous rasterize function is overloaded and does many other things as well).

Which disadvantages? no better performance or quality?

No such thing, but you loose the ability to use expressions and parenting properly. To compensate, you have to turn your layers into 3D layers which in turn results in slower rendering. The same goes for vector graphics based layers. The problem is, that this one switch actually does what instead should be 2 or 3 separate layer options. We can only hope, some day Adobe will hear us and sort those things out.

Mylenium thank you for your reply. But I still don't know how to solve the problem. The image contained in a sub comp keep the sub comp resolution, even though these images are really high res. So when I zoom (scaling it up in the main comp) on this sub comp the image quality get ugly in details.

>What to turn on, I don't know what you are talking about :sad:

Do you want I send the aep project ?

AE cannot see outside the comp area and thus it will still only use your sub-comp area. You need to make your sub-comp big enough to contain your image without scaling it. If that's not practical, create some simple expressions that allow you to scale and position your image in the sub-comp from your main comp. "continuous rasterize/ collapse transformations" is the little sun/ star icon in the timeline.
