There should be xBR and xBRZ "Resize Methods" or plugins in future Avidemux releases to enlarge pixel-art or videos of 2D retro games.

It is impossible to add xBR to the libswscale-based plugin. The feature is provided by a different library – libavfilter – not used by Avidemux. A capable developer would need to port the filter.
