The bit rate is calculated using the formula:
- Frequency × bit depth × channels = bit rate.
- 44,100 samples per second × 16 bits per sample × 2 channels = 1,411,200 bits per second (or 1,411.2 kbps)
- 1,411,200 × 240 = 338,688,000 bits (or 40.37 megabytes)

What is Mbps in video?
One megabit per second (mbit/s) equals 1000 kbit/s. In video, a higher bitrate accommodates higher image quality in video output. Bitrate for HD video, for example, is usually in the range of 5-20 Mbps. Standard-definition is typically 1-6 mbps and high quality web video runs at about 2 Mbps.
What is the bitrate of MP4?
How are data rates measured?
Data rate is measured in units of bits per second (written “b/s” or “bps”), bytes per second (Bps), or baud. When applied to data rate, the multiplier prefixes “kilo-“, “mega-“, “giga-“, etc. (and their abbreviations, “k”, “M”, “G”, etc.) always denote powers of 1000.
What’s the size of 4K files per hour?
So one hour of 4K footage (4096 x 2160) equals around 42 GB. Then, 25 hours (1 hour per day) equals around 1 TB. 1TB (the 4K H.264 4K files from a single GH4 camera) x 3 ( for the back up) = 3 TB of hard disk space total.
What is a data transfer rate?
A data transfer rate (DTR), is the speed at which data can be transmitted between devices. This is sometimes referred to as throughput.
