3.5.1 Adding Layer A/B

Layer A and Layer B are the main video layers used to create the Program output.

By default:

• Layer A is used as the main video.
• Layer B is used as the secondary video.

Combining Layer A and B enables single-screen, picture-in-picture, and dual-screen layouts.

1. Press the A button in the PICTURE IN PICTURE row on the front panel.
2. Confirm that the A button lights blue.
3. Select a source from the PROGRAM/B row.
4. Confirm that the corresponding source button lights red.

The selected source will be output as Layer A in the Program output.

Alternatively:

1. Select a source from the PREVIEW/A row.
2. Confirm that the corresponding source button lights blue.

Perform switching according to the current switch mode:

• CUT mode: Press the corresponding source button in the PROGRAM/B row to switch the source to Program output.

Adding Layer B

1. Press the B button in the PICTURE IN PICTURE row on the front panel.
2. Confirm that the B button lights blue.

After Layer B is added, mini-max enters picture-in-picture mode.

📢  Notes

mini-max uses single-screen mode by default. After Layer B is enabled, the system automatically switches to dual-layer mode.
