# Upscale images with super resolution

Before running the pipeline command for a model, follow the required [Prerequisites](https://docs.qualcomm.com/doc/80-70029-15B/topic/use-ai-hub-models-with-gstreamer.html#prerequisites)

Note

The input video needs dimensions of 128x128 for optimal results.

Run the following command to ensure your result is displayed on the connected display.

export XDG_RUNTIME_DIR=/dev/socket/weston && export WAYLAND_DISPLAY=wayland-1
