Earns its place in the blender_extensions library for keeping overscan setup inside Blender's Output Properties and documenting a Nuke/Natron compositor workflow for the rendered frames.
Render Overscan adds overscan support to Blender, letting you apply and manage overscan directly in your renders. Its controls live in the Properties editor under Output Properties, so the setup stays inside Blender's output settings.
To use it, start with a camera in the scene. If there's only one, the "Select Scene Camera" button picks it for you; with several cameras, you select the one you want manually. Set the overscan value in pixels, then press the "Enable Overscan" toggle. Once rendered, the overscanned images carry overscan data around the frame — the developer walks through a Nuke/Natron workflow that uses a Reformat node to return the image to its source resolution while preserving the bounding box.
The add-on is compatible with Blender 5.0 and newer and is released under the GNU General Public License v3.0 or later. Version 0.1.16 removed the viewport "OVERSCAN ENABLED" indicator following the deprecation of the bgl module. It's listed here as free.
Render Overscan is best for blender artists rendering overscan for compositing with undistorted footage or compensating 2D tracking.
Render Overscan is completely free to download and use.
Render Overscan is compatible with Blender 5.0 and newer. You can add it by dragging and dropping the extension into Blender, or by downloading the file and installing it from disk. Once installed, its controls appear in the Properties editor under Output Properties. The current release is version 0.1.16. If you're on an older Blender build, check the developer's page and version history for a release that matches your setup.
Render Overscan needs a camera in the scene first. If there's a single camera, press the "Select Scene Camera" button to pick it; when several cameras exist, select the one you want manually. Next, set the overscan value in pixels, then press the "Enable Overscan" toggle to apply it. All of these controls are found in the Properties editor under Output Properties, keeping the setup alongside Blender's other output settings.
Render Overscan produces images with overscan data around the frame. The developer describes a Nuke and Natron workflow: add a Reformat node right after the Read node that loads the image, choose your original pre-overscan resolution, set the transform type to None, and enable Preserve Bounding Box. That gives you an image at the source resolution with the overscan data retained around it.
Render Overscan is listed here as free, and it's released under the GNU General Public License v3.0 or later. You can add it directly through Blender by dragging and dropping the extension, or by downloading the file and installing it from disk. The add-on requires no special permissions. For current licensing terms, the latest version, and the version history, the developer's page is the place to check.
