the eliminated line along with each pair of adjacent video lines.

Working with Third-Party Filters
Motion supports After Effects-compatible third-party plug-ins (on the PowerPC
platform only). Once you specify the location of the third-party plug-ins in Motion
Preferences, they appear in the 3rd Party Filters category of the Library.
To set the path to third-party plug-ins:
1 Choose Motion > Preferences (or press Command-comma).
2 Click General.
3 In the 3rd Party Plug-ins section, click Choose (next to Search Path).
4 In the dialog, navigate to the folder that contains your third-party plug-ins, then click
Choose.
A dialog appears informing you that the path has changed and the change will take
effect the next time you open Motion.
5 Quit and reopen Motion.
The third-party plug-ins appear in the 3rd Party Filters” category of the Library and are
applied in the same manner as all other filters.
Note: If you specify an alias for the plug-ins, the plug-ins are not recognized.
