I matchmoved the shot where is getting out of his garrage and getting on the street.

Bouygues Telecom Entreprise are 2 commercials I worked on as a Matchmover.

Calibre de Cartier is the last commercial I worked on as a Matchmover. it was directed by Rob Chiu. Unfortunately I’m not allow to show the breakdown tracking shot. But at least I can share the final video

• Calibre de Cartier (flash version on Fubiz)

Here is a tutorial on how to convert your own Light Probe into the 9 coefficients needed into my ft-SSIBL plug-in (Screen Space Image Base Lighting).

I’m sorry for the poor sound, I hope you will still be able to understand !

Introduction

This shader will color an image based on a second input. I did it because I wanted to change grayscale into a variety of colors with a gradiant.

Introduction

This really simple shader let you combine 2 inputs channel into a new one. There is already something like that in AE, but I believe it is only working in 8 or 16 bits. This one is working in 32 bits (thx pixel bender). I just did it because sometimes I do need to combine map datas (as normal map & height map) for my shaders, since Pixel Bender is limited to 2 inputs.

Introduction

ft-SSIBL for “Screen Space Image Base Lighting” is based on a topic I covered in a previous post about Roy Stelzer’s “2.5D Relighting inside of Nuke”.  In this shader I tried to reproduced a few approach found in his Nuke script. So with a Normal pass (object or world), you will be able to do some relighting with a HDR map. The shader won’t compute the 9 coefficients (spherical harmonics) needed for you as describe in this paper : http://graphics.stanford.edu/papers/envmap.

The default value are from the Grace Cathedral, San Francisco Lightprobe http://www.debevec.org/Probes/

Introduction

This shader let you re-texture your rendering directly in After Effects. It use a UV pass as default input and a texture as second input. UV pass could be render from pretty much any 3d package.

Those two shaders try to mimic Martin Scorsese’s The Aviator movie effects. The codes are based on snippet found on VFXTalk.com, Blender source code & Aviator VFX behind the scene website.

My tutorial for AETuts+ is finally out !!
It covers Time Remapping, Waveform to keyframe conversion, expression, … I got really inspired by watching all those reels from motion designer or filmmaker with music most of the time from Hecq. I was wondering how they did their editing and cuts, so I came up with this idea. I don’t know if it’s the way they did it, but this is my approach.

Hope you like it !!!
