Dynamic watermarking with SVG

Binary Buddha
How do you scale an input graphic when trying to do a watermark that scales according to the video resolution?

So far, I got `ffmpeg -i $input -i $watermark -filter_complex "overlay=x=(main_w-overlay_w)/2:y=((main_h-overlay_h)/4)*4" $output`.

But that requires a static image; i.e. a PNG I’m using right now.
