Render Overscan

About extension

Extension adds overscan support to Blender. The add-on controls are located in the Properties editor under Output Properties. First, you need to have a camera in the scene. If there’s only one camera, you can simply press the "Select Scene Camera" button. If there are multiple cameras, you can manually select the desired one. Then, set the desired overscan value in pixels and press the toggle button "Enable Overscan." When overscan is enabled, you will see a warning text in the viewport.

How to use overscanned images.

You've rendered your overscanned image, right? What's next? Load it into your favorite compositor. I’ll explain using the Nuke/Natron workflow as an example. First, add a Reformat node right after the Read node that loads your image. Then, select your source (pre-overscan) resolution, set the transform type to None, and check the box Preserve Bounding Box. Now you have an image in the source resolution with overscan data around it.
