The script will loop any amount of selected layers from the furthest in-point and the last out-point by pre-composing and doing a dissolving loop. It will then apply an expression to the looped comp so that it can be stretched infinitely from either the in or the out-point.

There is an option to use the Blend effect instead of using opacity to make the dissolve.

HOW TO USE:

• Select the layers you want to loop.
• Trim the in-point and out-point of the layers to where you would like the loop to be.
• Run the script from the Scripts menu
• Choose the dissolve length in frames
• *Please note that you should use the Blend Effect option when looping items that are transparent

If you double click the script file and open it in ExtendScript Toolkit you can set a couple of user variables:

• set the suffix to be used for 1 layer loops or the name of the looped comp for multi-layer loops
• the default dissolve length
• whether the script should prompt for a new dissolve length when run
• whether to use the Blend effect instead of using opacity to create the loop

Version History:

• 1.1 Now works properly with transparent items using the blend effect – Mar 2010
• 1.0 Initial Release – Feb 2010

For example:
Hero_Diffuse.[0-100].exr
Hero_Reflection.[0-100].exr
Hero_Shadow.[0-100].exr
Bg_Diffuse.[0-100].exr
Bg_Reflection.[0-100].exr
Bg_Shadow.[0-100].exr

The script will ask for the delimiter character.
In this case, entering _ will put the items into 2 folders

• Hero
• Bg

This script also works in Adobe Photoshop (Watch demo video for install instructions). To run it in Photoshop install the script in the Scripts folder which is located inside the Presets folder in the Photoshop app folder.

This script was used in this tutorial at Aetuts+

Usage Instructions:

1. Select the audio layer and run the Keyframe Assistant “Convert Audio to Keyframes”.
2. Run the script and choose which layer you wish to mark or split. If the layer you want does not show up, select the comp and press the Refresh button.
3. Set the audio level at which the markers should be place. The script uses the “Both Channels” value from the Audio Amplitude layer which is created after running “Convert Audio to Keyframes”. A marker will place placed when the audio crosses that value and another marker won’t be placed until the audio drops below and above again.
4. Choose one of the 3 output options:
   • Place markers on a layer
   • Split the layer
   • Create a new text layer with incrementing numbers

The layer will then be marked or split at the threshold points. If you choose to create a new text layer then the newly created text layer will have keyframes with incrementing numerical values which can be used to trigger expressions.

Version History
• v1.2 Added marker numbering option, improved delete marker funciton to work within work area – jan 2010
• 1.1 Fixed “undefined” alert bug – nov 2009
• 1.0 Initial Release – oct 2009

The script has 2 operating modes:

1. An old school method which opens each project, checks all the footage items paths then replaces the path to the new path, imports the footage item from the new location and saves out a new project. This method works with CS3 & CS4.
2. A CS4 only mode that takes advantage of the new XML file format introduced in CS4. It opens each project, saves it out as an XML project (if original project is already in .aepx format then this step is skipped) and then does a search and replace on the XML file. This process is much faster since it doesn’t have to import all the footage items.

USAGE:

• It is recommended that you run the script in test mode first to see how After Effects sees the footage paths. Once you have that info you can accurately enter the search and replace strings. Note that on Mac XML projects path are separated by a colon : )
• Recurse subfolders will process and subfolders.
• Use Regex will cause the script to use Regular Expressions syntax in the search string. If you don’t know what Regular Expressions are then it’s probably best that you don’t use this option.
• Generate log will create a text file with all the results and errors encountered by the script.
• If you are running in test mode you will be able to preview the search and replace results before actually doing it. The script will save a text file with the results of the search and replace operation.

Version History

• 1.02 Fixed “Suppress dialogs” bug 01/2010
• 1.01 Fixed “undefined” error when write to network preference was not set 11/2009

Usage:
• Queue whatever you want to render in your render queue the way you would normally do but instead of hitting render in the RenderQueue, hit BG Render in the script palette.
• That’s it, a separate window will open in the background and will begin rendering leaving AE free for you to continue working in.

Troubleshooting:
• Make sure you don’t have any illegal characters in your path or your project file. Illegal characters include accents, apostrophe’s and eccentric punctuation.
• BG Renderer only runs in English, it will fail if you are running a different language.
• You can also check the BG Renderer Error FAQ

HYPA recently completed a project involving thousands of files from multi-pass rendering making up many image sequences. The finder struggled to list the directory contents, even after several minutes, however Immigration sailed through the files and immediately became an essential part of our workflow saving lots of time and streamlining the process. I can’t imagine working with After Effects and image sequences without it.

Immigration turns the pain usually associated with importing and batch replacing files in After Effects a joy. While browsing for import, it shows file sequences as one line item instead of a long list of files. Immigration uses a custom algorithm to scan the file system at speeds dramatically faster than even the OS can. In our testing a server folder with 30,000 files that takes over 5 minutes to open in the finder opens in 12 seconds in Immigration (and that includes file-sequence detection!). If you frequently find yourself waiting for the OS to open folders then you will love Immigration.

You can then select more than one file or sequence and either import them all at once or batch replace files already in your project. You can easily assign a frame rate to all imported files at once. Immigrations’ Auto-Match Replace™ algorithm will automatically match files with similar names so you don’t have to. It shows you a preview so you can make sure the matches are what you want. It color codes the match depending on how close it is. This is convenient if you name your revised files with a new version number or date.

If your files are already neatly organized in folders, Immigration will duplicate and maintain the folder hierarchy within the After Effects project.

You can customize Immigration to only search for certain file extensions, and file age. So for example you can tell Immigration to only display .exr files that are less than an hour old. You can also tell it to include or ignore folder by name so if you would like it to ignore a folder in your hierarchy (an archives folder for example) you can do that easily.

It has the option to add the layer name to the marker name as well as keep any existing marker names.

• Add Parented Null to Selected Layers.jsx will create a new null and parent all the selected layers to it.
• Add Parented Null to Each Selected Layer.jsx will create a parented null for each of the selected layers. The new null can have a custom name defined in the User Variables section and also has the option of including the name of the layer that is parented to it.

This is the CS4 update to the popular Throttle script.  It works with the new multi-processing throttle system that was introduced with CS4 that manages how many CPU’s are to be left free for other applications.  This version also adds a little known hidden preference that allows you to set the quality of the Toggle Pixel Aspect Correction button in the Comp View. (Please note that After Effects needs to be restarted after changing the PAR quality)

The package includes both Throttle and Throttle-n-Purge

Please watch the video tutorial to familiarize yourself with Zorro.

Zorro is an embeddable panel script which needs to be installed in the ScriptsUI Panels folder inside the Scripts folder.  If a ScriptsUI Panels folder does not exist you need to create one.  Please watch the script installation tutorial in the F.A.Q.’s
