Feature Request: xBR and xBRZ frame resize/upscale

[Mohsen]

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



ffmpeg does support xBR frame upscale by using the following command...

4xEnlarge example:

Code Select Expand

ffmpeg -i input.png -vf "xbr=4" output.png

Here are some examples...

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.
