I just learned that the Beamer class option 'aspectratio=169' can be used ... now I need to find where it is to be specified.
Works just fine.
This still leaves the resolution to be adjusted with ffmpeg.
If I correctly understand the ffmpeg wiki page on scaling the following command line will set the resolution to 1920x1080 while preserving the 16:9 aspect ratio because both dimensions are in the correct ratio: ffmpeg -i <video>.mp4 -vf scale=1920x1080:flags=lanczos output scaled.mp4 After checking scaled.mp4 I can rename it to <video>. I chose the lanczos filter because that's what I use on digital elevation models and other raster images when reprojecting them in GRASS gis.
