Enter the storage capacity and the product of the bitrate and codec ratio into the calculator to determine the recording time.
Recording Time Formula
The following formula is used to calculate the recording time.
RT = SC / (BR * CR)
Variables:
- RT is the recording time (hours)
- SC is the storage capacity of the recording medium (GB)
- BR is the bitrate of the recording (Mbps)
- CR is the codec ratio (dimensionless)
To calculate the recording time, divide the storage capacity of the recording medium by the product of the bitrate of the recording and the codec ratio. The bitrate is the amount of data processed per unit of time, and the codec ratio is a factor that depends on the format or codec used for the recording. The higher the bitrate and codec ratio, the shorter the recording time, and vice versa.
What is a Recording Time?
Recording time refers to the duration or length of time that an audio or video recording lasts. It can also refer to the amount of time available for recording on a specific device or medium, such as a cassette tape, DVD, or digital storage device. The recording time can be influenced by several factors including the storage capacity of the recording medium, the quality of the recording, and the format or codec used for the recording.
How to Calculate Recording Time?
The following steps outline how to calculate the Recording Time.
- First, determine the storage capacity of the recording medium (SC) in gigabytes (GB).
- Next, determine the bitrate of the recording (BR) in megabits per second (Mbps).
- Next, gather the formula from above = RT = SC / (BR * CR).
- Finally, calculate the Recording Time.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
storage capacity of the recording medium (SC) = 500 GB
bitrate of the recording (BR) = 10 Mbps
codec ratio (CR) = 0.8
