Calculate the total memory required to store a 5 minute video in SVGA system with 24 bit true color and 30 fps.
5Answer
An SVGA screen has a resolution of 800 × 600 pixels. With 24-bit true colour, each pixel needs 24 bits = 3 bytes.
Memory per frame
800 × 600 × 3 = 1,440,000 bytes
Number of frames
5 minutes = 300 seconds, at 30 frames per second: 300 × 30 = 9,000 frames
Total memory
1,440,000 × 9,000 = 12,960,000,000 bytes
≈ 12.96 × 10⁹ bytes ≈ 12.07 GB (dividing by 1024³), without compression.
