Cataloging Options - Update Tab
Option | Choices | Description
General | Regenerate Thumbnail | If disabled (not checked), the Thumbnail in the catalog record will not be changed. If enabled (checked) the thumbnail will be updated if the source file has changed, or if Update Unconditionally is selected.
| Extract Thumbnail | Controls whether Portfolio looks for an embedded Thumb-nail or creates its own. This option is ignored if Regenerate is disabled.
| Extract Description | Replace: Replaces the existing description with the new one. Append: Adds the new description to the end of the old one.
| Extract Keywords | Replace: Replaces existing keywords with the new ones. Append: Adds the new keywords to the existing keywords.
| Always Detect Digimarc | When disabled, Portfolio will only look for a Digimarc watermark when it attempts to generate a thumbnail, not when thumbnails are extracted. When enabled, Portfolio attempts to generate a thumbnail for every item and checks for Digimarc data; the Extract Thumbnail option is disabled.
Document Text Indexing |  | Indexes the text of Adobe Acrobat and Microsoft Power-Point files by adding each word to the catalog index. Preview the original file to read document document text.
Video* | Use Poster Frame | Use Poster Frame for thumbnail (by default, the first frame). If the first frame of a group of movies is black, for example, one of the other options can be used for the thumbnail.
| Use Frame # | Allows you to choose a particular frame for the thumbnail (for example, Frame #2).
| Use Frame After | Allows you to select the frame occurring after a specific time interval (specify number of seconds).

* QuickTime movies (.mov) only; not compatible with m1v, mpeg, swfl, and animated gifs.
