Rolling Shutter Correction using Optical Flow and 3D tracking

Here's a little something we've been working on in our spare time - correcting for CMOS rolling shutter artifacts.

We've noticed that using the phrase "CMOS rolling shutter" in a conversation gets you one of three responses:

Huh?
Not really an issue is it?
It has ruined my life.

Wobble correction still looks a bit funky, but panning looks nice.

Yeah. Definitely not ready to be included in Furnace. But It's a good babystep towards a future where the application can understand the parallax and wobble it's seeing and then warp it out.

Also I think they accidentally just showed off the new Nuke6x 3d tracker interface for the first time.

Shaky camera + Rolling shutter = Wobble.

Edit: Ok... But with the name digital FX and 2k+ posts I think you know very well what it is...

As we say in Brazil I'm trying to teach the priest to hold the mass.

The free deshaker plugin for virtualdub can correct rolling shutter panning and tilting artifacts(wobble, jello, any way you want to call it). What it doesn't do is correct moving subjects within the frame.
