QFHD and resolution above 72 dpi

[VectorCat]

My video workflow if 4k. Is there any advantage to working im QFHD at higher-than-72dpi, say 600, 1200 dpi, for use in print? Would the higher resolution matter for video?

Thank you

In print the physical dimension matters (inch, mm) and influences the visual resolution. You can downscale a video / screenshot with 72 dpi to achieve 300 dpi (the usual resolution for print of pixel images). An image/layout with more than 300 dpi would not be an advantage in the print result, whereas a resolution between 72 (or ~150) and 300 dpi may seem sufficient to your eye and depends on the video material.
