Question: What is the sum of Mpix with a maximum fps HDRX of less than 12 with a width larger than 5120?
Columns: ['Frame size', 'Width', 'Height', 'Mpix', 'Aspect Ratio', 'Maximum fps', 'Maximum fps HDRx', 'least compression at 24 fps', 'least compression at maximum fps']
Types: ['text', 'real', 'real', 'real', 'text', 'real', 'real', 'text', 'text']
Sample row: ['5K', 5120.0, 2700.0, 13.8, '1.9:1', 12.0, 6.0, 'NA, 24 fps is not possible at 5K', '5:1']
SQL:

assistant: SELECT SUM("Mpix") FROM "Table" WHERE "Maximum fps HDRx" < 12.0 AND "Width" > 5120.0;
