The “Top” form factor refers to a compact desktop controller, similar in footprint to a small mixer or stream deck, but with dedicated timecode-focused features:
Go to Settings > Shortcuts in vMix. Click "Add." Perform the action on your hardware (e.g., press the T-bar). vMix will learn the midi/usb input.
Critical mapping for the "Top" layout:
| Action | vMix Shortcut | Why it's Top Tier | | :--- | :--- | :--- | | Cut | Cut Direct | No transition delay | | Auto | Auto Transition | Triggers current transition effect | | Preview 1-8 | Preview Input 1-8 | Changes "Next" source | | Program 1-8 | Program Input 1-8 | Changes "Live" source | | PTZ Pan/Tilt | PTZ Move (Relative) | Smooth camera moves | | Record | Record Start/Stop | Visual confirmation on button | | Stream | Stream Start/Stop | Emergency off switch |
When all your main inputs (Cam 1-8) and outputs (PGM, PVW, REC, STREAM) are physically labeled and static on the top row, your fingers learn the geography. You stop looking at the controller. You look at the vMix output monitor instead.
The vMix UTC Top is most valuable in scenarios where failure is not an option:
A vMix UTC Top is defined by its physical layout, which mirrors the logic of a traditional broadcast control panel. Key components include:
The intelligence of a UTC Top lies in its communication layer. Unlike simple USB keyboards that send key presses, a vMix controller sends specific commands via:
A critical feature of a true "UTC Top" is bidirectional feedback. When you press a button, not only does the command execute, but the button’s backlight changes state automatically based on vMix’s internal status. This prevents the operator from ever being uncertain about which source is live.

We recommend performing Windows® 10 installations enabling UEFI with a GUID Partition Table (GPT).
Some features may not be available if you use the Master Boot Record (MBR) style partition table.
