Is there an anti-aliasing filter for AE?  I've got some old footage pulled off D1 & 1" masters that I'm enlarging to 1080p.  The edges get real jaggy.  Any ideas out there?

Thanks!

    How are you doing the enlargement? Are you using AE's built-in Detail-Preverving Upscale effect (under the Effect>Distort menu)? Are you using a third-party plugin? Or are you just scaling up regularly?

    You could use the Find Edges effect to drive a track matte that you use for a CC Vector Blur effect... that might help.

    Thanks for responding!

    My version of AE (v11) doesn't seem to include the "Detail Preserving Upscale" effect (?)  I have experimented with RedGiant Instant 4k but that did not cut it.  RedGiant ReSizer shows promise, however.

    You are asking quite a lot. AE does a fairly good job with Detail Preserving Upscale providing you have properly separated the fields and captured the original D1 footage at sufficient color depth and quality. If it were me I would start by transcoding the original footage to a 10 bit or better progressive production format with 4:4:4 color or a high bit depth image sequence, then I'd process the digital intermediate.

    Even with 3rd party solutions you'll get a better result if you render a DI than you will get with compressed original.


    Thanks!  Unfortunately, re-transcoding was not an option in this case.  Matter resolved with RedGiant ReSizer.  On to a new job, better equipped to deal with future issues like this one.  DB
