CREATE TABLE table_name_5 (max_fps VARCHAR, mpix VARCHAR, frame_size VARCHAR)

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_name_5 WHERE mpix > 8.4 AND frame_size = "4k 16:9"
SELECT COUNT("max_fps") FROM "table_name_5" WHERE "4k 16:9" = "frame_size" AND "mpix" > 8.4
