Overscan is a Blender addon that allows you to render your image with an overscan, with three different options.
Once installed, a new Overscan option will apprea in the Output settings under the reder resolution.
MODES:
Percentage will allow you to specify a percentage that you would like to add to the render resolution. For example, if the original version is 1920x1080 and you add 10%, you will endup with a resoultion of 2112x1188.
Extra pixel will add the desired amount of pixel in the overscan area of the image. So if you ask 100, you will get 2020x1180.
Specific X resolution will set the X resoution to the input and adapt the y resolution to keep the same aspect ratio.
Note that for every change that you make you need to press the reset button first.
This will work for any rendering engine.
