Screen Grabber collects thumbnails at even intervals from a movie. Optionally adding movie information, and time stamps.
Can batch-process large collection of movies. Supports all video and audio codecs supported by Quicktime on the current system. To add support for more codecs, for example Window Media Video (WMV), install additional Quicktime components such as as Perian or Flip4Mac.
Perian installed for a single user is not compatible with Sandboxed applications on Mac OS X Lion. If you have problems capturing AVI, WMV and other codecs provided by Perian try re-installing for "all users".
