Wiggler Blurs Footage?
Hola Creative COW.
Looks to me like the Wiggler in After Effects also adds a slight blur to a shot, at least when working with interlaced footage. Is this correct? Is this avoidable?
Thank ye.

first I would separate the fields. Interlaced footage can be tricky. Is there a natural motion blur to the footage to begin with? and stating the obvious, check that the Motion Blur setting is off.

Thanks for the response.
Motion blur is off. Fields are properly interpreted and I’ve also tried running the Wiggler effect on a 59.94fps comp with fields fully separated. No change. The shot itself is static so the blur is definitely being added by Wiggler. Also the footage is uncompressed 8-bit, so this isn’t a problem of recompression.
It really just appears to me that the Wiggler effect adds a slight amount of blur as part of its functioning. It’s fairly subtle so it could be that most people just accept it/don’t notice it, but it is there.
Thinking about how fields are processed, I actually can’t imagine how horizontal position could be adjusted by any program or effect WITHOUT creating blur. Magic, maybe. I was kind of hoping someone on the COW could send some magic my way.

well, Jared. You know your stuff. That tells me, without seeing a frame of it that you are right, that simply distorting an image over a number of pixels. Say taking a 3 pixel wide sharp line and distorting it
to 3 or 4 times inevitably will lead to same ‘softening\blurring’ of an image. My thought is that if you want it as ‘focused’ as as possible try a ‘median’ filter or any number of more robust sharpen filters to help the image a bit.Good luck.
