Calculate the size of a video file (in GB) with a duration of 64 seconds, a frame rate of 32 frames / sec, a resolution of 1280

Calculate the size of a video file (in GB) with a duration of 64 seconds, a frame rate of 32 frames / sec, a resolution of 1280 * 640 pixels and a color depth of 16 bits. The volume of the audio component of a video clip can be neglected.

The bit depth of the color is 16 bits, therefore 2 bytes are needed for 1 pixel.
Let’s find the number of pixels in one frame: 1280 * 640 = 819 200 points.
Let’s find the weight of one frame: 819 200 points * 2 bytes = 1 638 400 bytes.
Let’s find the weight of 32 frames: 1 638 400 bytes * 32 frames = 52 428 800 bytes.
Find the weight of 64 seconds: 52 428 800 bytes * 64 seconds = 3 355 443 200 bytes.
Let’s convert the number to gigabytes:
3 355 443 200 bytes / 1024 (we get kbytes) / 1024 (we get mbytes) / 1024 (we get gigabytes) = 3.125 GB.
Answer: 3.125GB.
