How to set up Kaption from zero

You do not need mods or file changes. The only important part is selecting the right screen area so Kaption can read the game dialogue cleanly.

01

What Kaption needs from you

Kaption reads pixels from a chosen part of your screen. That means setup is mostly about drawing a clean rectangle around the game dialogue, not around the whole screen.

A slightly larger region is better than a tight one, but do not include speaker portraits, UI hints, or the translated overlay itself.

  • Use a long NPC line when choosing the region.
  • Leave a little vertical room for multi-line dialogue.
  • Redraw the region after changing resolution or UI scale.

02

Where most setup problems come from

If subtitles flicker, repeat, or look like nonsense, Kaption is usually reading something it should not. The common case is the translated overlay sitting inside the OCR region.

The fix is simple: move the overlay above or below the dialogue area, then redraw the capture region around only the original in-game text.

Step by step

  1. 01

    Download and install

    Use the public installer from the landing page. The app is self-contained, so normal players do not need to install .NET manually.

  2. 02

    Open the game first

    Start Genshin Impact or Honkai: Star Rail and enter a dialogue scene before drawing the region.

  3. 03

    Draw the Dialogue Region

    Capture the original game dialogue, not the translated overlay. If you want the full screenshot walkthrough, use the dedicated region guide.

  4. 04

    Play one long conversation

    Test on a talky NPC or event scene. If a line is clipped, redraw the region a little taller.

Questions

Do I need to configure every time?

No. Kaption remembers regions per game. You usually redraw only after changing resolution, UI scale, monitor layout, or game window mode.

What should I do first when OCR fails?

Show the region, check whether the overlay is inside it, and redraw the box around only the original dialogue text.
