Pixel Bender : ft-2-strip technicolor & ft-3-strip technicolor shader for After Effects


Introduction

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.

UPDATE : Now ft-2-strip technicolor & ft-3-strip technicolor as merged to a one filter called “ft-Technicolor”

Download & Sources


How to install it ?


Just copy the .pbk file into your “Support Files” folder in your AE install directory

Experimental Animation based on sound with After Effects via AETuts+ (Audio Reactant Time Remapping)

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 !!!

UPDATE – Cubic Lens Distortion Pixel Bender shader for AE (with scale & chromatic aberration

cubic lens distortion & chromatic aberration



If you haven’t seen my previous post yet, here is the Syntheyes’ Cubic Lens Distortion algorithm ported to Pixel Bender.


New Features

  1. Scale factor : works exactly as Syntheyes Scale Lens Workflow (v2)
  2. Chromatic Aberration : based on Martins Upitis‘s GLSL posted here (v2)
  3. Blue/Yellow Chromatic Aberration based on Dorian modification (V3)



Download

  1. Download ft-CubicDistortion.pbk here : http://aescripts.com/ft-cubic-lens-distortion/
  2. Place it in your “Support Files” folder (which is in your AE install folder)
  3. Launch AE
  4. Look for the effect called Cubic Distortion

Source Code

just download the file at http://aescripts.com/ft-cubic-lens-distortion and open it with your notepad application

PixelBender Cubic Lens Distortion for After Effects


Introduction


If you are doing Matchmove, you probably bumped into Lens work-flow issue, where you have to un-distort the footage in your matchmove software, then track it, and export a new undistorted footage, so your client can compose the 3d rendering on top of it and then distort it back.
I don’t really like this work-flow, since for instance AfterFx do not have Cubic Lens Distortion FX and it would be really hard for the client trying to match the distortion back.

After watching Victor Wolansky’s FXPHD Class on SYN202 (syntheyes) about Lens work-flow, I thought : “hey why not porting the lens distortion algorithm ?”. Pretty easy to do, since I already did it for HLSL & Martins Upitis did port my shader to GLSL !
Thanks to SSonTech for sharing there alogrithm


Pixel Bender Cubic Lens Distortion :

Not much to say, it does what it suppose to do ! You can copy & paste values from Syntheyes and it will match perfectly (or it should at least). See the screenshot below.

  1. Download CubicDistortion.pbk here : http://aescripts.com/ft-cubic-lens-distortion/
  2. Place it in your “Support Files” folder (which is in your AE install folder)
  3. Launch AE
  4. Look for the effect called Cubic Distortion

UPDATE : now with scale factor & chromatic aberration, see the post here

Thanks to Jerzy Drozda Jr (aka Maltaannon) for his great tips about Pixel Bender.

So now, you can create a new comp with your distorted footage > pre-comp it > undistorted it with the shader > track it in syntheyes > export the camera to a 3d package > render the scene > import the render into your pre-comp > desactivate the shader. Should match perfectly 🙂

Blender Quick Tips : How to create masks in the compositing editor

Since there is no mask in the “Compositing Editor” of Blender yet, I found a simple tricks which could work pretty well especially in case of color grading.

You’ll see nothing really fancy here since the mask can only be square (or pretty close to a square shape though). But if you check out Colorista for instance, the two allowed shapes are ellipse and rectangle.

RollingShutter Plugin by the Foundry for After FX and Nuke Released !!!

I talked about the Foundry working on solving the rolling shutter issue on a previous post. It seams they were waiting the Siggraph to announce it. At the time I though it was only for Nuke, but the great news is they also port their plugin to After Effect CS3 and CS4.

It seems they fixed the horizontal panning issue, but still not the vertical one, which at this point looks impossible but I’m actually waiting for another paper on stabilization which should show up at siggraph too. Anyway it’s going to help a lot for matchmove !!!
