Understanding Search in VIDIZMO

Overview

Search is often at the front and center of what we do and with the expansion of digital media in the enterprise, the time employees spend searching is only expected to surge. The rampant use of enterprise video across organizations, for instance, means that a great deal of business-related information will now be stored in the form of video for employees to extract insights and knowledge from.

How Search Works in VIDIZMO

Keeping in view the inherent challenges faced by the users in searching for relevant information, VIDIZMO has implemented a powerful search tool that helps users to quickly obtain the desired results from the information spread across the portal. 

For example, based upon permissions assigned to the user, a search can be performed to bring up results which match keywords defined in entities such as Tags, Author Name, Closed Captions (CC), Category names and those defined as Custom Attributes. When the search is performed from the Portal Homepage or the Portal Library, VIDIZMO will look into these entities to bring up the results. 

Users & Groups has its own search and will bring up the results based on the search criteria and requires Administrative permissions described below under the section Administrator Level Filters.

For a search mechanism to fetch the most optimal and efficient results, it should also have the ability to employ smart search technologies such as automatic speech recognition (ASR), optical character recognition (OCR), facial recognition, etc. to quickly and easily extract insights from video using artificial intelligence. Using the VIDIZMO's ability to thoroughly index stored content's metadata, search works globally across the platform to get all videos across all Portals within an Account or when performing a search within a specific Portal. VIDIZMO search works on all metadata, including titles, tags, description, long description, category, the author as well as any in-video content which is indexed and searchable.

Another aspect of VIDIZMO's search mechanism is its relevance-based search, which means that the searched Media or User with the highest weight will appear first. To narrow down the search, the platform performs a faceted search using filters created automatically using Tags, Author Name, Closed Captions, Category names, and user-defined Custom Attributes.

Here is how VIDIZMO uses in-video and platform-wide search:

• Search using metadata: VIDIZMO allows a thorough and detailed search of all videos in the platform using metadata such as video title, description, tags, hashtags, author or even by custom attributes such as publishing date, video type, live event date, department, company, location or any other required identifiers.
  
• Search by category: Videos under the same topic category can be collectively bundled and stored in playlists within VIDIZMO, which further improves its search effectiveness. A simple search would reveal results for all videos categorized under a particular topic, either individually or within an organized playlist.
  
• Search in closed captions (CC): Using its automatic speech recognition (ASR) software, VIDIZMO also generates closed captions or video subtitles that display the text version of spoken words on the video screen adding clarity to video and audio files. The text in the closed captions is indexed so you can search by words or on-screen subtitles that appear in a video.   Moreover, CC increases the searchability and also assists those with hearing disabilities, an accessibility requirement for 508 Compliance. VIDIZMO supports CC for audio and video files with support for both existing closed captions or manually generated human transcripts to improve video search. VIDIZMO also enables indexing of all translated video transcripts and caption files so the user can search for terms within the video in their preferred language.

During video playback, a searchable transcript plays alongside the video enabling users to search within the transcript of the video to reach the desired moment within the video with ease. Moreover, by clicking on the transcript text, viewers can also jump to the desired section in a video.

In the transcription panel, enter a term, i.e., Sequestration (i), in the Search field, and if the searched term is found, all its instances get highlighted. 

• Search by video timestamp: VIDIZMO allows search based on a given timecode or segment within a video. For instance, you can simply search a time interval in a video to refine the search from that point onwards. Specific instances can be searched in a video by navigating to that timestamp within a video through the comments.

 
Here's an example:

I. Enter the time you wish to link and add it as a comment in the comments section.

II. When the comment becomes available, click on the highlighted link in the comment and you will be navigated to the required frame in the video.

Viewer Level Filters

Each section of the portal has a different set of filters available which the users can apply. The table below lists the sections with the filters that can be used to drill down to the most relevant media the user is looking for:

Administrator Level Filters

Since Administrators have access to administrative sections of the portal, they can use the filters available in these sections such as Media Management, Users & Groups, and other sections in the Control Panel:

Note: If a user has permissions to view media, only then it will be available in the search results.
