Deinterlacer that produces non-flickery 1080p?

[Asterra]

I've captured some video from an Xbox 360 over HDMI at 1080i60 4:2:2. It happens that I had access to ReVision Fieldskit, a deinterlacer which is highly regarded. I spent half the day on the borrowed PC rendering off my raw 1080p60 video, newly deinterlaced.

I'll supply the workflow I used so that perhaps a problem can be identified by someone more experienced. First I imported a 1080i60 clip into After Effects. I interpreted the footage as needing to have the fields separated, top field first. I made a comp with the footage, changed the comp's framerate to 59.94, and added the Fieldskit deinterlacer effect to the footage within the comp. The settings I chose to use within Fieldskit deinterlacer were:

Timing mode: =Motion Estimated Blend, 1 Frame Per Frame
Field Order: Upper First
Fill Method: Blend

Everything else was left at default. These settings seemed to provide the best result (edges were nice and smooth) without the subtle corruption introduced by using a "Best 3 Neighbors" or "Best 5 Neighbors" fill method.

The trouble I have with the resulting video is that sharp horizontal edges flicker very conspicuously. While I can understand why this might happen when dealing with interlaced video - deinterlaced or not - the fact is I wasn't expecting a top of the line product to exhibit such results, and that's why I suspect I may have failed somewhere in my workflow. It ought to be a pretty simple matter, in terms of contemporary deinterlacing technology, to produce a more flawless result with sharp horizontal edges. Case in point: The average LCD TV - including the one I am staring at - does not have this problem. The flickering I see with Fieldskit's output is a bit like what I'd expect from a rather more transparent deinterlacing process from the likes of VirtualDub or Avisynth.

Anyway, thanks in advance for any pointers, suggestions or recommendations.

QTGMC will give you far better results . It's based on the original TGMC , designed to eliminate bob flicker

The RE:Vision FX Fields Kit deinterlacer is good only when you compare it to other retail deinterlacers; but they aren't remotely in the same league as avisynth deinterlacers

Yes. I would have to say that is a pretty impressive showing, and I'll definitely be giving it a spin. Thanks for the heads up. (And also thanks for subtly pointing out what to call the phenomenon I was trying to describe. It was on the tip of my tongue, I swear. ;p )

Where Fieldskit definitely shone was in restoring lost vertical resolution. It was almost like having 1080p to begin with. (But only with the motion detection mode.) It is my hope that QTGMC or something else can do the same in addition to avoiding the frankly absurd bob flicker.

I tested the FieldsKit deinterlacer extensively a while back. A friend of mine swore that it produced excellent results... Let's just say he no longer uses it.

You can't really restore the lost vertical resolution - it's gone. But you can attempt interpolate the missing information by using motion compensation and looking at past/future frames - that's what Q/TGMC do
