Crop

Crop lets you isolate a specific region of the input frame so that only that area is analysed by scopes and QC tools. This is especially useful when monitoring a Screen Capture source where the application window occupies only part of the screen, or when you want to focus analysis on a particular section of the image.

Crop overlay with position, dimensions, and aspect ratio

Opening the Crop Window

There are several ways to open crop:

Method	Action
Menu	View > Crop…
Keyboard	⌥C (macOS) / Alt+C (Windows)
Input strip	Click the crop icon on the input thumbnail
Context menu	Right-click an input source and select Crop…

When crop is active, the full-screen overlay shows the current frame with draggable crop handles.

Using Crop

1. Open the crop window — the full source frame is displayed as an overlay

2. Drag the edges or corners to adjust the crop region

3. Drag inside the crop rectangle to reposition it

4. The overlay displays the position (X, Y), dimensions (W, H), and aspect ratio of the cropped area in real time

5. Click Apply Crop to confirm, or Reset to restore the full frame

Keyboard Shortcuts

macOS	Windows	Action
⌥C	Alt+C	Toggle crop window
⌥R	Alt+R	Reset crop
ESC	ESC	Close crop window without applying

Per-Input Crop

Crop settings are saved per input source. Each connected input can have its own independent crop region. When switching between inputs or loading layouts, crop settings are restored automatically.

You can toggle crop on or off for a specific input slot using the Toggle crop action in the Action Editor or StreamDeck.

Crop and Snapshots

By default, snapshots include the crop. From version 1.11.9+ you can choose to take snapshots without the crop applied — useful when you want to capture the full frame for reference while analysing a cropped region.

Common Use Cases

• Screen Capture monitoring — crop to the video player or NLE viewer area and ignore the rest of the screen

• Letterbox / pillarbox removal — crop out black bars to get accurate scope readings of the active picture only

• Region-of-interest analysis — focus waveform, vectorscope, and histogram analysis on a specific area of the frame (e.g. skin tones, sky, shadows)
