VFX Breakdown: Town Extension

Posted on: No Comments

There’s a small engine behind the prop train in this shot which pushes the locomotive forward. Removing it required replacing the horse that runs behind it. I grabbed a time-offset translated version of horse for the replacement.

We had a number of photographs and plates of tents and people which we used to extend the town both on screen left and right.

At this point in the story, they crew building the railway should not have reached the mountain range we see in the distance. I translated the the sky down below the horizon to remove them.

Lastly, an artist generated particle smoke for the train. A live smoke element was used in other areas of the shot.

VFX Breakdown: Forest Fire

Posted on: No Comments

The 3D tracker in Nuke did an okay job on this shot, though it took a little more time to get a good track. Although the resulting point cloud sticks well, it’s distribution never matched a real world camera move.

I sampled four different forest fire elements from National Archive footage and projected stabilized versions of them on to cards to use with the tracked camera.

The larger smoke plumes are actually still frames with 3D luminosity based animated distortion to give it a faked sense of movement.

Lastly, the reflection in the lakes was a second flopped render of the same element masked into place.

Trailheads Promo for the NSMBA

Posted on: No Comments

This video features some fun motion graphics integrated into a promotional video for the NSMBA.

Each “trail head” image was composited together from stills. Instead of manually adding accelerating cuts between these composits, each image initially had the same duration. The acceleration in duration of each image was achieved using a time warp – this saved me a lot of editing time and allowed me to make a very accurate acceleration curve.

Spinning the NSMA wheel on their logo was completed entirely in 2D using components of their original logo. The basic concept was to remove the perspective, animate the rotation of the wheel, and add the perspective back in. With motion blur on and a camera fly-through, the result looks pretty cool.

VFX Breakdown: WW1 Battle Field

We had two live action elements for this shot, a dirt explosion and some dark billowing smoke. Some burnt trees were also photographed.

The rest was cobbled together from stills projected through a camera onto a ground plane and cards.

The ground plane has some procedural displacement to match the hills and valleys in the comp.

The camera shake is animated using TCL random expressions whose amplitude is an animated Nuke nob.

VFX Breakdown: Avalanche

Posted on: No Comments

One of the major shots for the season, we had one artist on the avalanche R&D for a month. Another artist worked on some smaller particle and fluid interactions.

Another artist was on the plane animation and mountain ground plane modelling.

I comped all these passes together for the most part using luminosity values of the avalanche to mask the plane.

I also had to re-project the matte painting of the plane’s skid marks through the 3D animated camera to integrate it with the background plate.

VFX Breakdown: Ice Shacks

Posted on: No Comments

This shot required the addition of a few ice shacks into the plate.

From stills taken by the supervisor, I made 4 unique shacks – one for the foreground and 3 for the background. The shacks are graded to match the plate, adding in light leaks and highlights.

To tie everything in, I added some haze using fBm noise. I created the falling snow using particles applying the alpha channel to a gradient so that the flakes are light over the dark sky and dark over the light snow.

Add camera shake and done.

Dog party in a bakery

From Beverly Hills Chihuahua 2, 2010. One of the baby chihuahuas had to sneak under the german shepherd. 32 hours of roto.

Completed in Nuke.

Near Collision

From Beverly Hills Chihuahua 2, 2010. Straightforward split screen.

Belt Dropping STEREO

From The Hole 3D 2009. Luma key for the background replacement. I also added some wiggle to the belt as it fell with internal mesh warp.

Completed in Nuke.


From The Hole 3D 2009. The puppeteer’s arm was visible frame right and some gaffer tape in the mouth needed to be removed. Roto, background tracked, resized and graded before being comped in.

Completed in Nuke in stereo.

Faceoff  STEREO

From The Hole 3D 2009. Tracking markers removed. Couple different mattes produced for the core and troublesome hair. The CG smokey volume and debris were added with the background for the multi-pass composite. Grade and camera shake added.

Completed in Nuke.
