New Google-powered add-on for automatic video categorization and tagging

Introducing Automatic Video Tagging and Content Categorization

Due to significant growth of the web and improvements in network bandwidth, video is now a major source of information and entertainment shared over the internet. As a developer or asset manager, making corporate videos available for viewing, not to mention user-uploaded videos, means you also need a way to categorize them according to their content and make your video library searchable. Most systems end up organizing their video by metadata like the filename, or with user-generated tags (e.g., youtube). This sort of indexing method is subjective, inconsistent, time-consuming, incomplete and superficial.

A well-organized indexing system lets you easily manage and organize your media libraries:

  • Enable personnel across your entire organization to find resources they may need
  • Increase engagement by helping your users find exactly what they’re looking for
  • Help you connect your users with common interests and help them find other content that would interest them
  • Increase sales or advertising revenue by determining the main subjects that interest particular users and integrating this information with your existing analytics/personalization tools to display relevant product recommendations or adverts

But ultimately, any sort of manual video categorization process would take huge amounts of time and resources.

Introducing Cloudinary's Automatic Video Tagging add-on, powered by Google Cloud Video Intelligence, which is now fully integrated into Cloudinary's video management and delivery pipeline. State-of-the-art machine learning allows for the recognition of various visual objects and concepts in videos, simplifying and automating the categorization and tagging process.

Using the Automatic Video Tagging add-on

Take a look at the following video of horses:

Using the add-on, automatically assigning resource tags to the video is as simple as adding 2 parameters when either uploading a new video or updating an existing video: set the categorization parameter to google_video_tagging and the auto_tagging parameter to the minimum confidence score necessary before automatically adding a detected category as a tag. For example, uploading the horses video and requesting automatic tagging for all categories meeting a confidence score of over 40%:

Ruby:
Cloudinary::Uploader.upload("horses.mp4", 
   :resource_type => :video, :categorization => "google_video_tagging", :auto_tagging => 0.4)
PHP:
\Cloudinary\Uploader::upload("horses.mp4", 
  array("categorization" => "google_video_tagging", "auto_tagging" => 0.4));
Python:
cloudinary.uploader.upload("horses.mp4",
  categorization = "google_video_tagging", auto_tagging = 0.4)
Node.js:
cloudinary.uploader.upload("horses.mp4", 
  function(result) { console.log(result); }, 
  { categorization: "google_video_tagging", auto_tagging: 0.4 });
Java:
cloudinary.uploader().upload("horses.mp4", ObjectUtils.asMap(
  "categorization", "google_video_tagging", "auto_tagging", "0.4"));

Once the categorization process completes, the information is returned to Cloudinary and all categories that exceed your specified confidence score are automatically added as tags on your video.

Below is a snippet of the upload response for the horse video:

{
...
tags"=>  ["animal", "freezing", "frost", "horse",  … ],
"info": {
   "google_video_tagging": {
      "status": "complete",
      "data": [
         [{"tag": "horse", 
          "start_time_offset": 0.0, 
          "end_time_offset": 12.6364, 
          "confidence": 0.8906},
          {"tag": "horse", 
          "start_time_offset": -1, 
          "end_time_offset": -1, 
          "confidence": 0.8906},
          {"tag": "animal", 
          "start_time_offset": 0.0, 
          "end_time_offset": 13.47364, 
          "confidence": 0.8906},

          ]
...

The benefits of video tagging

As can be seen in the example snippet above, various categories were automatically detected in the uploaded video and automatically added as tags. Each category is listed together with the start and end times of the relevant video segment (an offset time of -1 means the category represents the entire video) and the confidence score of the detected category, where 1.0 means 100% confidence.

Once the video has been categorized, that information can be shared with your analytics tools. Cross-examining both the categorization and usage data can yield valuable insights into how different videos impact engagement and conversion. Do the videos show indoor or outdoor scenes? Do they include people? Animals? This information can then be leveraged for AB testing and user profiling.

For example, you can test how different videos, (e.g., with or without animals) may impact engagement for a specific product or service, helping you utilize the optimal content when designing websites, apps or email campaigns. You may determine that a user watching videos of parties, events, sports, and music is probably a college student or young adult, whereas a user that uploads videos of parks, children, and playgrounds is more likely to be a parent. This knowledge can help you focus your content on the right audience and increase engagement and conversion.

Additionally, a well indexed, organized library of videos can be leveraged across your entire organization. Tagging is particularly useful if your company has a constantly growing library of digital assets that need to be made available for various teams within your organization. For example, if the marketing team needs a video of a dog for an email campaign, they can search for and select the most appropriate video.

With the growth in video comes greater bandwidth use, which is not only costly for your IT budget, but for your visitors as well. Beyond the expense, there is the user experience to consider. The heavier the page, the longer it will take to load, and the greater likelihood visitors will abandon your site. Page load speed is also an important factor in SEO ranking, so clearly video is something we need to take seriously and get right.
