Created attachment 169038 [details] XML file for avfilter.fillborder SUMMARY According to the MLT and ffmpeg documentation, the filter/effect supports 7 different modes but only 3 are available in the dropdown. The XML definition file lists all 7 modes. Also, the filters appears to be keyframable but the XML attributes are missing. SOFTWARE/OS VERSIONS Linux: Pop!_OS 22.04 LTS KDE Frameworks Version: 6.0.0 Qt Version: 6.2.2
