Video Metadata – Optimize to Increase Your Viewers

What is Video Metadata?

Video metadata is text inside the video file that references the video. Search engines use video metadata to show video results. YouTube combines video metadata with other video viewership data to determine when to show videos among its top results. Likewise, Content recommendation systems, such as Netflix’s famous machine learning algorithms, also use video metadata to accurately personalize videos.

How is Video Search different from Web Page Search?

The beasts of burden of the internet are the web bots that crawl every single page there is. Web crawlers determine the suitability of a page for search results on two inputs:

• Text content
• Backlinks to the web page.

Search Engines cannot however automatically crawl videos. Likewise, backlinks are not relevant for video search.

For this reason, search engines have to rely on text data associated with the video. This text data, in the form of video title, video description, and video tags, is what search engines use to determine which videos form the best results for a search query.

Optimizing Video Metadata

Optimizing search results is very important for video creators. Being on the first page of a Google search query is a guarantee that your video is going to be viewed many times. The elements of video metadata that can be optimized to make videos more search-engine friendly are:

Video Title

Video Title should be accurate, and should also reflect what your viewers would want to watch. You should look up Google’s Keyword Planner to find out the most popular keywords. Keyword research would help evaluate which is better – to attempt to rank high for a competitive video category, or to rank top for long-tail search terms.

Video Description

Video descriptions are an introduction to viewers and to search bots alike. An accurate and detailed video description could reassure potential viewers that your video is worth watching.

Video Tags

Video tags are the categories that your video falls into. In YouTube’s autoplay feature the succeeding video has to share at least one video tag with the current video being played.

Aggressive metadata optimization is discouraged. Besides being a bad user experience, misleading video metadata can cause your videos to be blacklisted on YouTube and other video platforms.

Is search really all that important?

Search Engines are the backbone of the internet. By creating a set of rules according to which web pages rank for keywords, Google has created the entire field of search engine optimization. For online businesses, there is a world of difference between ranking 1st on the first page and ranking at the bottom of the first page.

An effective search engine ensures that your users find what they are looking for. With a small collection of videos, you can put them all up for users to choose for themselves. That’s where dashboards work best. However, search becomes increasingly important as the library of content increases.

Is Search the only way my users can get new content?

Video platforms such as Netflix have tried to move beyond search results to show new videos. The reasoning goes that time spent searching for content is also the time when users are likely to leave the video platform. To minimize this time, Netflix has created its content recommendation system.

Netflix’s recommendation systems use metadata at their core. Netflix currently has over 25,000 genres into which it classifies its film collection. TV and film analysts tag films and series into genres. Each film can belong to multiple genres at the same time. These genres (such as here), are metadata that Netflix uses to train its machine learning algorithms.

Autoplay, content recommendation systems, and playlists all rely on metadata. Although machine learning technologies being applied to further improve user experience, video metadata still forms the base over which these systems work.

Is there other video metadata?

The prefix meta is applied whenever something refers to itself. This sentence is meta because it refers to itself. As is this XKCD comic.

Video files also carry information about themselves beyond the title, description, and tags. This metadata refers to the v ideo file itself. Data about the video file include video codec, video resolution, video encoding (constant bit rate or variable bitrate), links to the content decryption key, among others. This metadata is only useful to the video player playing back the video.

For video creators, video metadata also comprises of information about the video production process. This includes:

• Camera information
• Kind of camera & Lens
• Aperture Size
• Video frame rate
• Shutter-speed
• Clapperboard Information such as:
  • Scene
  • Take number
  • Camera angle
