Export Video in Standard Definition

Can someone please tell me if there is a way to export videos in Shotcut to be in Standard Definition, not High Definition?

I have changed the resolution size to be smaller than 1280 x 720, but it’s still in HD when I upload it to YouTube.

Thanks for the help.

SD means ‘Standard Definition’ and refers to 480p. HD means ‘High Definition’ and refers to 720p and 1080p

There are different SD formats. Before you start your project, choose something “SD” from Settings > Video Mode. NTSC is roughly 30 frames per second, and PAL is 25 fps.
