OBS Setup

Adding the Overlay

1. Add a Browser Source in OBS
2. Check Local file and select the overlay HTML file
3. Set Width to 1920 and Height to 1080
4. If streaming at 60 FPS, set the browser source FPS to 60 (default is 30)
5. Layer game/camera sources below the overlay in the source list

Game Source Transform (Edit Transform - Ctrl+E)

Right-click a game source > Edit Transform (or Ctrl+E) and enter the exact values below.

For all sources, set:

• Positional Alignment: Top Left
• Bounding Box Type: Scale to inner bounds
• Alignment in Bounding Box: Center

Standard Layout — Edit Transform Values

Panel size: 935 x 515

Source	Pos X	Pos Y	Bounding Box W	Bounding Box H
Set 1 (top-left)	15	15	935	515
Set 2 (top-right)	970	15	935	515
Set 3 (bottom-left)	15	550	935	515
Set 4 (bottom-right)	970	550	935	515

These panels are slightly wider than 16:9 (935:515 = ~1.815:1 vs 1.778:1). A 1920x1080 game source with "Scale to inner bounds" will be cropped ~6px top and bottom — barely noticeable. Use "Scale to outer bounds" instead if you prefer thin black bars on the sides with no crop.

Gap Layout — Edit Transform Values

Panel size: 780 x 439 (exact 16:9)

Source	Pos X	Pos Y	Bounding Box W	Bounding Box H
Set 1 (top-left)	15	91	780	439
Set 2 (top-right)	1125	91	780	439
Set 3 (bottom-left)	15	626	780	439
Set 4 (bottom-right)	1125	626	780	439

These panels are exactly 16:9. A 1920x1080 game source fits perfectly — no cropping, no black bars.
