Note: if using a custom resolution, try to pick one where units are divisible by 16
Total streams at 1200x672 and has said: "I picked 1200 because it's divisible by 16 which is better for h264 encoding"
Even though 1195x672 is closer to 16:9


Evidence has been provided that 64:49 is a closer resolution than 4:3 (marginally).

At 4:3 in the center, the circle is slightly too wide and goes farther than the true circle, however 64:49 is closer.
