There are three versions of Unmult:
- The latest version of Unmult is acquired through a paid Red Giant Universe subscription.
- Unmult 1.1 is free, was maintained from ~2014-2017, and can be downloaded for Mac & Win
- Unmult 1.0 is free, was maintained from ~2009-2014, and can be downloaded for Mac & Win
For Unmult 1.1 and 1.0, place the downloaded file in:
Note that none of the versions of Unmult are compatible with one another.
This means if a project says it's missing Unmult even after installing one of the versions above, you will need to try installing the other versions to resolve the issue.
Older versions of Unmult may not open in newer versions of Mac OS X, as Mac cannot identify the developer of older files. This can sometimes be circumvented by right-clicking the file and selecting Open, then opening the file with After Effects.
Even though After Effects may kick back an error message after this step, the plugin might then operate normally once you try using it in your projects.
If none of the versions of Unmult work for your project, or you have other questions about Unmult, file a ticket with support.
