CREATE TABLE table_15400 ("Frame size" CLOB, "Width" FLOAT, "Height" FLOAT, "Mpix" FLOAT, "Aspect Ratio" CLOB, "max. fps" FLOAT, "lowest possible REDCODE at 24 fps" CLOB)

What is the max fps of a camera with mpix larger than 8.4 and frame size of 4k 16:9?
SELECT COUNT("max. fps") FROM table_15400 WHERE "Mpix" > '8.4' AND "Frame size" = '4k 16:9'
SELECT COUNT("max. fps") FROM "table_15400" WHERE "Frame size" = '4k 16:9' AND "Mpix" > '8.4'
