How Subtitle Localization Process Supports Streaming Platforms' Expansion in Asia

To ensure the subtitle localization process is effective and can support platform expansion in Asia, there is a systematic process to follow:

Target Market and Language Analysis

The first step is to identify the target market or viewers. This includes their primary language and regional variations. For example, the Mandarin language has distinct regional variations, and its usage context is not always the same across different areas. This is important because language use can shift depending on region and context.

Language and Cultural Context Adaptation

To make subtitles feel natural to viewers, localizers need to adjust the dialogue to the viewers’ cultural context. For example:
Original dialogue: “You’ve brought shame to this family.”
Literal subtitle: “Kamu membawa rasa malu ke keluarga ini.” (Indonesian)
Localized subtitle: “Kamu mempermalukan keluarga kita.” (Indonesian)
The localized subtitle feels more natural and suits the way Indonesian people communicate.

Adjusting Subtitles with Technical Standards

Subtitles need to follow technical standards such as:

  • Characters per second (CPS). For example, Netflix guidelines state that CPS for adult programs in English templates is up to 17 CPS, while for children’s programs it is up to 15 CPS.
  • Display time. One popular rule in display time is the 6-second rule, which states that a full two-line subtitle should last for 6 seconds to be read comfortably by viewers.
  • Visual synchronization.

Quality Control and Consistency of Terminology

This step is necessary to ensure that:

  • The terminology used is consistent
  • Readability
  • Context accuracy

Viewer Experience Evaluation

Subtitles need to be evaluated to ensure that they meet the following standards:

  • Understandable
  • Do not disturb visual elements
  • The emotion of the story is still maintained
