SCRATCH - Adobe After Effects - bridge


As of version 9.0, SCRATCH comes with an option to create a direct link between SCRATCH and Adobe AfterEffects (S2AE). To make this link work properly there are a number of settings you need to enable in After Effects.

Custom Command

The first step in creating a direct link between SCRATCH and AfterEffects is to create a Custom Command in SCRATCH of the type AfterEffects. simply open the Custom Command tab in the System Settings panel and create a new custom command. On Windows, SCRATCH will automatically search for the AfterEffects executable. If you have multiple version installed, you can always manually switch by selecting another version. On OSX, SCRATCH always automatically uses the latest version on the system.

Once the Custom Command is created, the button will show in the Tools menu in the Construct and in the right click menu in the Player.

After Effects Round Trip

To ensure the proper working of the link and to be able to automatically feed back rendered results from AfterEffects into your SCRATCH project, you need to adjust a number of settings in AfterEffects.

S2AE panel

S2AE comes with an UI script giving an extra panel in AfterEffects to add your active comp to the render queue and send it automatically to SCRATCH's render folder of the project. To activate the S2AE panel, copy the file s2ae_ui.jsx file from the SCRATCH installation folder into the After Effects script folder:

  • Windows: from the C:\Program Files\Assimilate\Settings\Script folder, to the C:\Program Files\Adobe\Adobe After Effects CC [version]\Support Files\Scripts\ScriptUI Panels folder.
  • OSX: from the /Library/Application Support/Assimilator/Defaults/Script folder to the /Applications/Adobe/Adobe After Effects CC [version]/Scripts/ScriptUI Panels

After you copied the script and launched After Effects, the Windows menu will show the s2ae_ui.jsx script. When selecting that, the extra panel will appear that you can dock into your Workspace and will stay displayed after you restart AfterEffects.

AfterEffects Preferences

In AfterEffects and go to your preferences:

  • Windows: Go to Edit > Preferences > General > and check on "Allow Scripts to Write Files and Access Network"
  • Mac: Go to Adobe After Effects > Preferences > General > and check on "Allow Scripts to Write Files and Access Network"

You can also uncheck "Show Start Screen at Startup"

Prepare an Output Template

It is important to create an output template. This will be the default template for exchanging between the 2 applications to maintain consistent File Format, Bit Depth, en/disable Alpha channel and Color management.

In After Effects, go to Edit/Templates/Output Modules where you have to prepare your render settings for the script.

Create a new settings called «scratch» and click on «Edit...» button to set the file format you want (Tiff sequence with trillions of Colors (16bits Tiffs RGB) is recommended).

Finally, to avoid wrong Color Interpretation, disable the color management in AfterEffects.



Once you have the s2ae_ui and a «scratch» output module, you can exit AfterEffects.
Any shot coming from SCRATCH and rendered in AfterEffects will show up in the SCRATCH project again in the project Tray, from where you can drag/drop it into your timeline or composite.
