Summary
Animated version of https://www.nesdev.org/wiki/File:NTSC_video_ragged_box.png.
The second frame is made by offsetting the frame by 1 "scanline".
The filter is replicated as two Convolution Matrix passes in linear light space using GIMP 2.10.32. The kernels used are [1 1 0 1 1] and [1 3 4 3 1] respectively.
After filtering the resulting kernels, an approximate 2.4 gamma curve is applied using the Levels tool, setting the middle slider to 1/2.4 (approx. 0.42).
This derivative work is also licensed under the WTFPL.
