Analysis Reports

Some Hybrik analyzers can generate a PDF report or may be able to generate their results as a machine readable json file. For example, the VMAF analysis will give you the VMAF scores in the task result JSON, but you can also output per-frame analysis results as a separate file to storage.

Usage

Results from an analyzer task can be accessed in a few different ways:

• JSON file written to storage
• PDF file written to storage
• JSON result retrieved via API
• JSON result viewed via web console

Report File

Generating a report will provide the results from all analysis types in the task, with the exception of some comparative types (VMAF, SSIM, MS_SSIM). This option can be added to an Analyze task by including the following reports array in the payload as shown below. Read our API Docs on reports for more info.

[ 
  {
    "uid": "analyze_task",
    "kind": "analyze",
    "payload": {
      "reports": [
        {
          "file_pattern": "{source_basename}_analysis_report.pdf",
          "location": {
            "storage_provider": "s3",
            "path": "{{destination_path}}"
          }
        }
      ],
      "general_properties": {
        "enabled": true
      },
      "deep_properties": {
        "audio": [
          {
            "track_selector": {
              "index": 0
            },
            "volume": {
              "enabled": true
            }
          }
        ]
      }
    }
  }
] 

Results File

The comparative analysis types VMAF, SSIM and MS_SSIM have the option to generate a results file, which provides detailed data on a per-frame level, as well as calculated averages and other statistics. You can read more in our Analyze Task Documentation.

Analyzer Results via API and web console

The results of any analysis performed in a job can be found in the job summary json, which is available via the API or the Hybrik Web Console.

Web Console

Select a job on the Completed Jobs page that contains an analysis task. Click the More Actions button and then choose Export Job Summary from the drop-down options. This will automatically download the job summary json to your local system. Open the json file and search for the text analyzer to find the relevant section. There, you can scroll down to see the analysis results.

API

You can retrieve the job summary for a completed job using the REST API, which is explained in detail here: https://docs.hybrik.com/api/v1/HybrikAPI.html?#get-job-result
