anti-alising in AE
can it be done? i made a project, the raw footage was converted from analog to digital, and it had quite a lot of dots…not a very sharp image…
a friend asked me if i can put anti-alising on the footage…
Can it be done? If not in AE, then in what?
Thank you,

This could be a result of either one of two things: the quality switch or interlacing. In your timeline there is a swith with an image of a diagonal line of poor resolution. When you click on it the line becomes smooth. (It’s there for every applicable layer.) If you don’t see it, click on the Switches/Modes button on the bottom to reveal it.
As far as the interlacing goes — the best thing to do is just turn it off. To do that, you right click (PC) or Control click (Mac) on the footage file in the bin and go to “Interpret Footage”. The dialogue window will let you turn off the interlacing. -

Well… if your source footage is interlaced and you wish to apply effects to it that move pixels, (blur, rotation, scaling, etc.) you definitely want to keep field separation ON.
If the source is progressive, indeed you want to make sure field separation is OFF.

Based on my experience it’s best to always keep it off. It’s as if AE puts another layer of interlacing that doesn’t quite match the original and the whole thing looks pixilated in the end. When you turn it off, your footage comes out unchanged — in its original state, and the effects can be applied on the original footage, not after its been processed by AE. I know this doesn’t make sense, but it is that way. I’ve tested this hundreds of times.

Try scaling or rotating your interlaced footage without separating fields… You won’t like the results. Or try motiontracking or rotoscoping…
If you only do color treatment or mild effects, you can actually get by without separating fields, if you export with the same field order. If you mix and match DV and Digitbeta, it’s a different story. But if it works for you…
