Available in VPC

Media analysis is the process of analyzing media assets using the multimodal engine and extracting metadata. To generate an index by analyzing a media asset:

Start media analysis

  1. Access the Media Intelligence workspace.
  2. Add the video file to be analyzed to your project.
  3. Click [Start analysis] for the media asset you want to analyze.
    • Alternatively, click the checkbox for the media asset you want to analyze, then click [Start analysis] at the top of the interface.
  4. Configure the following settings in [Set analysis options] of the Start analysis popup:
Item Description
Analysis engine Check the engine version information to be used for media asset analysis.
Scene length Set the length of automatically divided scenes to short, normal, or long, or enter it manually.
  • Short: Splits into short units for detailed analysis of specific scenes within the video.
  • Medium (default): Captures key changes while maintaining an appropriate flow between scenes.
  • Long: Enhances connectivity between scenes to maintain a more natural flow.
Analysis language The language used for video analysis.
  • Default value: Korean (ko)
  • Korean/English/Korean-English Simultaneous/Japanese/Chinese (Simplified)/Chinese (Traditional)
Voice effect detection Select whether to detect and extract voice effects.
  • When on, detects various voice effects (e.g., laughter, applause and music).
  • When off, voice effects are not detected.
Note

The configured scene length, analysis language, and whether to detect voice effects for image assets do not affect the analysis results.

  1. Configure the following settings in [Set analysis persons] of the Start analysis popup:
Item Description
Person detection Select whether to detect and extract persons.
  • When on, up to 10 persons are extracted.
  • When off, persons are not detected.
Person tag Select the persons to be detected from the person DB.
  • Unregistered person in the person DB: Detect as anonymous person
  1. After all settings are completed, click [Start analysis].
    • Once the analysis is completed, the index ID appears in the analysis results.
    • To cancel the analysis, click [Cancel analysis].
  2. To perform additional analysis, click [Add analysis].
    • You can analyze a single media asset multiple times.
Note
  • When setting the scene length, select Long for genres such as documentaries or dramas where dialogue is long and context is important, and Short for genres such as reality shows where scene changes are frequent.
  • When entering the scene length manually, enter both the minimum and maximum scene lengths. The minimum scene length can be set between 10 and 30 seconds, and the maximum scene length can be set between 25 and 300 seconds.
  • If confidence level filtering is set to 'high', you can obtain highly accurate results, but the chance of missing detections increases.
  • If confidence level filtering is set to 'low', you can obtain more detection results, but the chance of detecting unnecessary objects increases.
