Dual Mode lets you design, stream, and/or record horizontal and vertical video at the same time, with full creative control over each format.

Instead of creating separate recordings or editing clips later, Dual Mode allows you to build two intentional layouts in one session — one horizontal and one vertical.

This means you can simultaneously produce content for platforms like YouTube, LinkedIn, Facebook, Instagram, TikTok, and more, without sacrificing design or quality.

One session. Two outputs. Fully designed for each format.

To enable Dual Mode, you’ll need to make sure you’re using Ecamm v4.5 or newer. To double check what version you’re on, simply go to the Ecamm menu at the top and select Check for Updates.

Once you’re in the correct version of the app, you’ll find Dual Mode in the Options menu.

Options → Video Shape → Dual Mode (Horizontal & Vertical)

Once Dual Mode is enabled, Ecamm displays horizontal and vertical canvases side-by-side, allowing you to design each layout independently.

You can add different:

to each canvas.

When you go live or record, Ecamm will stream and/or record both formats simultaneously.

When Dual Mode is enabled, you'll see Horizontal Canvas Size and Vertical Canvas Size in the Options menu.

This allows you to control the resolution of each format independently.

These settings ensure each output is optimized for the platform it’s designed for, without needing to resize or crop later.

Because each canvas is fully customizable, you can design layouts specifically for how viewers will experience them on each platform.

For example:

If you want the same overlay in both canvases, you can duplicate it:

Method 1 — Right-click duplicate

This copies the overlay to the other canvas.

Method 2 — Option-drag

Hold the Option key (⌥) and drag an overlay to the other canvas.

Some overlays will automatically stay synchronized when used on both canvases. This includes:

If these elements appear in both layouts, they will stay synced during your broadcast or recording.

When designing scenes, it’s important to account for interface elements that may cover parts of the screen on certain platforms.

Ecamm includes Vertical Safe Zone feature in the Options menu to help with this.

The Vertical Safe Zone visually indicates areas that could be obscured by:

Using Safe Zone helps ensure that key elements like faces, logos, and text remain visible across platforms.

Dual Mode adds additional options to the live stream scheduling workflow.

When creating a new broadcast in Ecamm, you’ll see options to choose which canvas is streamed to each streaming destination:

Selecting Horizontal & Vertical will create two broadcasts on that platform, one for each shape. Only YouTube, Facebook, and LinkedIn support streaming both formats simultaneously.

When scheduling or managing a broadcast, you'll see horizontal and vertical icons next to each destination.

These icons indicate the video shape being sent to that platform. Click these icons to change the aspect ratio assigned to that destination.

If you've already scheduled a broadcast and need to change the format being sent to a destination:

Your updates will apply to the upcoming broadcast.

When recording with Dual Mode enabled, Ecamm will automatically create two video recordings, one horizontal, and one vertical.

Each recording reflects the layout you designed for that canvas. This allows you to immediately publish to different platforms without additional editing or cropping.

Dual Mode also allows you to control which format is used for other outputs within Ecamm.

When using Virtual Camera, you can choose whether the horizontal or vertical canvas is sent to the virtual camera output.

When using the Video Monitor feature, you can also choose whether the output uses the horizontal canvas, the vertical canvas, or the entire main window's output.
