Full Length Video Processing

Professionally Produced Content

Traditional Approach

Process is extremely time consuming limiting the number of clips that can be created.

Challenges

• Video is manually edited into shorter discrete clips

• Metadata about the clip’s contentis manually added

Much of the large body of content is not discoverable by search..

Content discovery is limited to clip’s metadata.

Viewer can not continue to view the long form content after the clip completes.

Not discoverableDiscoverable only by select key words




Nexidia Approach

Indexing and search are fast and automated processes.

The large body of content is now easily discoverable by search.

Content is discovered based on actual spoken words, not metadata so that content can be retrieved through many more key words.

Viewer can continue to view the long form content after the clip completes.

Producers can make additional premium content available for search that was not originally televised.

Benefits

• Search results correspond to specific points in video content.

• Search is based on audio track.




Nexidia Approach

Ability to take video that would otherwise be unavailable or unsuited for distribution and make it searchable as premium web only content.
