The workflow is as follows:
1. track a few points (something between one and four points is reasonable, even for complex mask shapes) that represent the basic movement of the object which you want to draw a mask around
2. keyframe the mask by hand in the first and last frame
3. use the script to predict keyframes in between (the script uses the tracker information for this prediction which is hence much better than the simple interpolation done by after effects itself)

Step 3) can be interleaved with manual corrections which leads to a quite fast, assisted rotoscoping workflow.

Tutorial 1

In this first tutorial I show how to rotoscope the shape of a moving car based on only four trackpoints, for simpler shapes often one trackpoint is sufficient.

Tutorial 2

In the second tutorial I describe some new features of Tracker2Mask that allow local modifications of masks.

Version History:

• 2.3 Made CS5 compatible and minor bug fix – Jun 2010
• 2.2 Bug fix that made AE freeze in some very rare occasions – Mar 2010
• 2.1 Initial release on aescripts.com – Aug 2009

Creating a Tracked Head Wound Tutorial from Aetuts+

I have created a new After Effects script called MochaImport. As you might guess, it simplifies the work with Mocha for After Effects. More precisely, it helps you to apply the Mocha tracking data in After Effects in whatever way you want.

With the script the following tasks can be done as one click operations:
• create corner pin
• create CC power pin
• create Red Giant Warp corner pin (Red Giant Warp plugin required)
• create AE trackpoints from Mocha track
• stabilize footage
• move layers according to track
• create a precomp in which the footage is stabilized while maintaining the movement in the original composition
• create a precomp in which the footage is stabilized and undistorted while maintaining the movement and distortion in the original composition (Red Giant Warp plugin required)

New features in MochaImport 2.0:

MochaImport works with Mocha for After Effects versions 1 and 2.

if you have problems
If you have problems, make sure you have installed the newest version of the script (currently version 2.02).

There where several problems to paste the tracking data into the textbox. Since this is a bug in After Effects and not in my script, I unfortunately cannot fix it. Therefore I deactivated the cut and paste now. You have to load the data from a text file now instead of pasting it from the clipboard.

report a bug

if you encounter any problems, best send me a mail to mmohlREMOVE_THIS_TO_AVOID_SPAM@gmx.de containing the following information
• a short description of what does not work
• the Mocha data you used (e.g. attached as text file; check whether there are differences in the text file you save in mocha and what finally ends up in the textbox of the script)
• the script version you used
• the operating System you use (Mac/Win)
• the AE version you use (CS3/CS4)
• a screen-shot of the AE window while the error occurs (this is not absolutely necessary, but in the bug reports I obtained so far, it helped to find the problem much faster)

Reporting bugs does NOT mean you should feel obliged to donate. By helping to improve the script you also make an important contribution.

fixed bugs
Problems with the script on CS3 (unknown UI element type “Group”) where fixed in Version 1.1.

The “pasted keyframe data has 29.97 fps but your comp has 29.97fps” error message is fixed since Version 1.2

Some issues with tracked fields/interleaced footage where fixed in 2.0

Some problems with corner pin data (Error Message “Invalid corner pin or transform data”) where fixed in 2.02

Features:

• Develop your motion graphics based on some Adobe kuler color theme and once you are finished see how it looks with a different one. Simply load a new color theme and your entire composition updates automatically.
• Do color correction based on Adobe kuler color themes by pushing highlights, midtones and shadows towards different colors of your color theme.
• Your projects still work on machines where the script is not installed.

Tutorial:

You can watch a tutorial explaining Chameleon on aetuts+.

How does it work?

Chameleon allows you to conveniently work with color themes from Adobe kuler in 3 steps.

1. Load color themes in After Effects either from color themes downloaded at the kuler website or via cut and paste from the kuler desktop application
2. Apply any loaded color theme to your comp with just one click
3. Dynamically link any color property within your comp to a color theme color. Once you load a new color theme, all linked color properties in your comp update accordingly.

Furthermore, with KeyTweak you cannot only modify masks but any other keyframed property. You can for example also use it to correct a drifting track or quickly refine the keyframed movement of a layer.
