I need a way to combine two 4:3 video streams side-by-side into one 16:9 output. Is there a device to do this

Question

For a research project, I need two video streams combined into one, and I need both to be full-screen and full-size. PIP won't work, and if I use a mixer to split the two inputs, I only get the right half of one and the left half of the other. The multiplexers that I've found won't output to 16:9, and most split the screen into fourths anyway. Is there any device out there that will do this?

Answer 1

is math tough?? 2 "full-screen and full size" 4:3 format picture side by side would require a 24:9 aspect ratio so 16:9 shape factor won't work. either you have to compress both videos slightly (pip type squeze) with resulting letter box bars on top and bottom or lose part of the pictures to side overlap. duh.
