the foundry fixing rolling shutter

No matter how much you research a camera, there is no substitution for forking over several thousand dollars, unboxing and holding it in your hands, shooting with it, converting the footage to ProRes and then looking at the wobbly vertical lines and going WHAT THE HECK?!  And if wobbly vertical lines and WHAT THE HECK aren’t descriptive enough for you, let’s get a neat and tidy explanation from Oliver Peters over at digitalfilms:

Rolling shutter artifacts – the so-called “jello-o-cam” effect – have been the bane of CMOS-sensor cameras, most notably the HD-capable DSLR still cameras. The short answer for why this happens is that objects move in place during the time interval between the data being picked up from the top to the bottom of the sensor. The visual manifestation is skewing or a wobble to the image on fast horizontal motion or shaky handheld shots. CoreMelt’s Lock & Load X is designed to be used for both standard image stabilization, as well as reduction of these artifacts.

If you continue reading Oliver’s post, he has a very nice write up of CoreMelt Lock and Load X.

The Foundry RollingShutter

Yet there is a link to The Foundry’s RollingShutter plug-in for Nuke and After Effects a bit down the page, and this is what I’ve found to be the nearest thing to magic I’ve seen in some time.

Yes, it’s 500 bucks.  Yes, you need to have After Effects (who has Nuke outside of an FXPHD VPN license?). Yes, it takes a loooong time to render.  But it doesn’t zoom in on your image to correct for rolling shutter like Lock & Load X does.  If I’m doing something wrong, please someone let me know because I would love to not spend 500 bucks; however, the zooming in is a deal breaker for me.  Regardless, RollingShutter does and amazing job!  And there is a free 15-day fully functional trial which you can download here.  Here’s the settings to use according to The Foundry’s website:

Whilst we’ve been using this tool in house here, we’ve found that the following are good correction amounts for some of the cameras we’ve been shooting with:

  • RED One: 0.32
  • Canon 5DmkII: 0.56

So while I haven’t bought it yet I am playing around with the free trial.  And so far, looks like this will take the place of a new lens.

Disclosure, to comply with the FTC’s new rules

None of the manufacturers listed above are paying Peter Salvia to write this article and, so far, none have sent him any samples or demonstration items.  Peter is a B&H Sales Affiliate and receives a commission from items linked to B&H and purchased through this site.  Oh yeah, and he’s an Apple Certified Trainer so you can derive his bias for yourself.
