You can also create additional thumbnails, for example one every 10 seconds.
Use the Build Thumbnails command to rebuild the poster thumbnails of selected clips (after changing the thumbnail size for example).All the thumbnails in a catalog with the same tape name and whose timecode lies between the "in" and "out" point of a clip are available for display with that clip. (Note that larger thumbnails increase the size of catalog files and the time to open them.) You can select the size of thumbnails in Preferences.Thumbnail images are created when you import a movie or still image into a catalog, typically for the first, last and middle frame of each movie or scene, though there is a Preference option to control how many thumbnails are created (or even to turn off automatic thumbnail generation altogether).Thumbnails are stored in the catalog along with the clips (so they remain available even when the media file is offline).Subclips refer to parts of a media file, specified by a time offset from the start of the file, and don't involve creating new files or modifying your original files.)
