Quickstart: Using the console for video classification

In this quickstart you will go through the process of annotating videos using a custom model.

Enable the API

Visit the AutoML Video Classification UI and click Enable API.

Create your dataset

  1. Once the API is enabled, go to the AutoML Video Classification UI and click Get Started.
    (Click Get Started
    The following screen appears:
    (Specify name for datase
    (1) specify a name for this dataset
    (2) select Video Classification
    (3) click Create Dataset

  2. The following screen appears:
    Provide Cloud Storage URI
    (1) Provide the Cloud Storage URI of the CSV file that contains the URIs of your training data.(see Prepare data)
    In this quickstart, use:

    automl-video-demo-data/hmdb_split1.csv

    (2) Click Continue to begin importing your data.
    The following screen appears:
    Importing data

Once the import process has completed you will receive an email with a link to the dataset in the Videos tab.
Importing data

To view any errors that occurred during the import process, switch to the Import tab and check any error messages.

Train your model

  1. Now that the dataset has been created and processed, go to the Train tab and click Start Training.
    Start training
    The Train new model screen appears:
    Start training view
  2. Click Start Training.
    Training is now initiated for your model. For this particular dataset, the service will email you with a link to the results.
    Deployed
    The service automatically deploys your model.
  3. Click the Evaluate tab to get more details about F1, Precision, and Recall scores, etc.
    The Evaluate view appears: Evaluate view

Classify a video

To make a prediction using your custom model—that is, to classify a video, select the Test & Use tab for the model.

Test your model

  1. In the Input CSV field, add:
    gs://automl-video-demo-data/hmdb_split1_test_gs_predict.csv (see Prepare data)
  2. Under Results bucket, click Browse to select, or create a directory within your Cloud Storage bucket where the annotation results will be stored. When creating your bucket, make sure the location is specified as US-CENTRAL1.
    Bucket
    For example:
    Bucket example
    You may actually want to create a specific 'results' folder in your Cloud Storage bucket to hold the annotation results. By doing so, you can more easily access older predictions by loading the video_classification.csv file contained in the results directory.
  3. Click Get Predictions.
    You will receive an email with a link to the dataset.
    Configuring a prediction for AutoML Video Intelligence

The process for getting predictions can take some time, depending on the number of videos that you want annotated.

When the process has completed, the results appear on the page for the model under Recent Predictions. To view the results, do the following:

  1. Under Recent Predictions in the Predictions column, click View for the prediction you want to look at.
  2. Under Video, select the name of the video you want to see the results for.
    Results of AutoML Video Intelligence prediction

View the results

In the results for your video annotation, AutoML Video Classification provides three types of information:

  • Labels for the video. You can find this information under the Segment tab below the video on the results page.
  • Labels for shots within the video. You can find this information under the Shot tab below the video on the results page.
  • Labels for each 1-second interval within the video. You can find this information under the 1 Second Interval tab below the video on the results page.

If you want to see more labels, you can change the threshold score when you request a prediction. AutoML Video Classification only displays the labels that are above the specified threshold.

If the prediction fails, the results in the list show a red icon on the Recent Predictions list.

If only one video in the prediction attempt failed, the prediction shows green in the Recent Predictions list. On the results page for that prediction, you can the results for the videos that AutoML Video Classification annotated.
