Alias issues …

[Angus Mackay]

Hi Nic,

It’s hard to know how bad the aliasing is without seeing the actual footage.

However…….. IMHO AEs poor Anti Aliasing is probably, and inexplicably, the greatest weakness the application has. Given that PCs are now as powerfull as they are, I can’t understand why Adobe has done nothing about this. The quality difference between text elements and fine lines rendered in AE and (for example) Discreet Systems is unreal. AE seems able to render minute detail created by filters beautifully, I don’t really know why text and artwork has to be so poor.

I had no idea about this…I’ve heard people say the ‘quality’ of pictures that come out of Discreet systems is second to none, didn’t realise they meant anti-aliasing. sorry to shift topics a bit, but could this poor AA’ing be the cause of scrolling credits nightmares that always seem to pop in AE?

possibly, but it it is often due to interlacing… if you render in fields and you credit don’t move in whole fields (even numbered whole pixel increments) then you’ll get bad jittery effect. the anti-aliasing effect can be solved too by forcing or limiting the movement to whole pixels.

dave laronde a great job describing a process to create a flicker free if you want to search the cow… and i created an expression based on it that can be downloaded at http://www.mercuryjones.com/aepresets.html. there are a few controls for creating the movement for field rendering along with sliders for front and end padding.

I know this thread is from 5 (five!) years ago but I was experiencing some aliasing issues in CS5.5 and I was able to overcome them by doing a “Save RAM Preview” in the composition menu.

I thought this might work because I didn’t see the aliasing effects until the mov was rendered and it worked. Not sure if it’s the best workaround but I was about out of ideas.

Just something to try if anyone comes across this thread and can’t figure out anything else.
