PreComp becomes Blurry, why??
I have a weird thing happening here in AE.
I have a keyed video in a precomp. That precomp now goes in another comp where it gets scaled down and cropped – the composition changes size which crops the video. Finally this Comp is nested/placed in a new comp where it is arranged with other videos.
So normal AE compositing and all, nesting and precomposing, but something weird is happening. The 2nd precomp that I am placing in the MASTER Composition is appearing blury. So to check what’s up I placed the origional keyed footage in the same comp and gave it the same scale and … this one appears sharp and normal.
There seems to be something up with AE when you scale footage in a precomp and then view in a final comp.
Anyone solve this, or is there some setting I need to switch.
(The setting in all the comps have “preserve resolution when nested” checked in the advanced tap in the composition settings.
In the photo you can see the left being the footage scaled in the current comp and the blurry footage on the right which was scaled in a precomp.

Hi, try turning on collapse transformations for your comps.

Yes, collapse transformations did it. Which is great! But why does it happen when “collapse transformation” is not selected?
Thanks

The way I understand collapse tranformations is like this, If in one comp I scale a layer down to 10% of its original size and then I scale a comp containing that comp up 10 times, collapse transformation joins the math for displaying the 2nd comp into one operation like this scale = 0.1*10 which equals 1 so the layer in the nested comp is displayed at its original size without being pixelated. When collapse transformations is not selected, the scaled down layer is scaled up as if it were a small raster image and you get distortion. An example of when you need to have collapse transformations turned off is when you are using AE’s motion blur.

Similar thing happened to me but it wasn’t the collapse transformations switch that worked for me. i was using a camera and its focus range was throwing me off.
i just double clicked the camera in my timeline to bring up it’s properties then unchecked the enable DOF switch.
