Display question
One HDMI program output is not the same as the specification’s total-output count or the USB interface’s list of uses.
The answer
Short answer Four HDMI inputs and one HDMI program output. The USB-C port has several documented uses, which are not documented as all available at once.
The model-specific ATEM Mini Pro ISO specification lists four HDMI Type A inputs and one HDMI program output. Its separate total-output figure of two must not be read as two HDMI output sockets. One USB-C interface has several documented uses, but their listing does not establish that all are available simultaneously.
Why the simple answer is not enough
Use the exact Pro ISO PDF. The manufacturer’s combined technical-specification website includes neighboring models with different port inventories.
The labeled panel diagram and Connections table distinguish the HDMI program output from inputs 1–4 and the USB-C interface.
The single USB Type-C 3.1 Gen 1 interface lists external-drive recording, webcam output, control, updates and panel connection. This alone does not resolve simultaneous webcam and external-drive operation.
The Standards table lists no Ultra HD video standards. The description of finishing in Ultra HD through relinked media is a post-production scope, not an Ultra HD HDMI input/output mode.
| Documented connection | What the source establishes | What still needs checking | Evidence |
|---|---|---|---|
| HDMI inputs / program output | Four HDMI inputs and one HDMI program output. | Total outputs is not the HDMI socket count. | C008F (private workspace) |
| Single USB-C interface | Several documented recording, webcam and control uses. | Simultaneous webcam and external-drive use is not established by that list. | C004J (private workspace) |
| HD versus Ultra HD scope | No Ultra HD video standards listed for this exact model. | Finishing/relinking wording is not a live Ultra HD port capability. | C008G (private workspace) |
