using app.findMenuCommandId() is nice to avoid problems when the ids change with a new version, but it makes the script UI language dependent. app.executeCommand(app.findMenuCommandId("Close")); only works, for example, with the English version. app.executeCommand(app.findMenuCommandId(loc...

I just published the ExpressionTimeline on Aescripts . It allows to limit the duration of expressions and comine them. You can for example modify a wiggle expression such that wiggles only for a certain amount of time. It works with arbitrary expressions and you don't need to touch the code of the e...

In this AE tutorial, I show how to fake motion blur for a corner pin using expressions.



In the tutorial I use the Mocha tracker but the expressions work with any kind of corner pin.

This After Effects tutorial shows how to use the smooth expression for stabilizing a shaky shot:


There is also a German version.

In this After Effects video tutorial about corner pin with Mocha there is another example of how you can use the speed (and direction) of a corner pin point to fake motion blur:

In principle, rotoation could be done, but it is difficult to integrate in the interface in an intuitive way: Currently Tracker2Mask works with an arbitrary number of trackpoints. Rotation works only for exactly 2 Trackpoints and it is not clear to me, around which point everything should rotate. Th...

For the rotation: This is not possible with Tracker2Mask. The best here is probably to place the mask on a rotating layer.

There are different options: (a) Use my script MochaImport (www.aescripts.com/mochaimport) to import Mocha Corner Pin Data as four AE trackpoints. (b) Copy-and-paste the position-keyframes of your NULL to the attachpoint data of a new trackpoint such that the trackpoint moves with your NULL without ...

I have created an After Effects script that simplifies the usage of the Mocha Tracker with After Effects. If you use Mocha for After Effects(or if you didn't so far because it seemed to be too complicated) you should take a look at it. A free download as well as a video tutorial can be found at http...

Are you talking (a) about the spacial interpolation between the points of the mask or (b) about the temporal interpolation between keyframes? for (a) I think all information you have are the inTangents and outTangents of the shape object. If a vertex, its inTangent and its outTangent are located on ...

Hi everyone, my AE script KeyTweak allows you to conveniently modify any property that has many keyframes (as for example animated masks, keyframed position/transparency/scale data of layers, trackpoints, parameters of effects or what ever). The usual problem with keyframes is that once you have int...

This will help you:

Thank's for this hint! I new about the possibility to add new trackpoints but I was also not aware of the ability to track the trackpoints of a tracker separately. Concerning the trackpoint selection of tracker2mask, I think the following behaviour would be best: - for each selected layer on which n...

I must have accidentally disabled the download option. It should be downloadable now. @jaist: Thanks for the typo hint. I will fix it, but it should not affect the script: I just did a copy and paste of my entire implementation of transformation matrices (see this thread ), but this function is actu...

A new version of the script is online. It allows the local manipulation of parts of a mask which is explained in this new tutorial: http://www.vimeo.com/2535683 I also tried to colourize the freeze-button, but it did not work since buttons do not seem to have a backgroundColor property and then I go...
