What is Bitrate or Bit rate, what does it mean? What is Audio Bitrate, Video Bitrate, how does this parameter speak? Let’s find out with Gia Thuan Shop through this article.
Watching: What is Data Rate
What is bit rate(Bitrate)?
Bitrate or Bit rate, or R variable, is the number of bits transmitted or processed per unit of time. It sounds hard to understand. You just need to understand simple. It’s like the speed at which water flows into a lake. The faster the water flows, the faster it will be filled.
Similarly, the higher the bitrate number, the more information it carries. The more quality the content. However, along with that, the equipment to handle it must also meet. Otherwise, there will be a situation of jerking because the device cannot handle it in time.
This term is used a lot on audio and video files, the purpose is to refer to the amount of data transferred in a certain period of time. Depending on the use case, the units used to measure bitrate are usually kbit/s (kilobits per second) and Mbps (megabits per second). Whatever unit is used, the higher the bitrate number the better, providing the same high speed or quality as I mentioned above.
For simple understanding, reading here is enough. Reading more just makes the brain more tired.

What is Audio Bitrate
?As mentioned above about Bit rate. Then Bitrate Audio is used to refer to the transfer rate of an audio file or file. Audio files here include popular formats such as: mp3, wav, ogg, aac, amr, wma, flac,….

Simply put, the higher the Audio bitrate, the better the quality of that file. Sound will be transmitted more fully than with lower Audio bitrates.
MP3 is an audio format that provides lossy compression. Sound quality increases with increasing bit rate. In general, mp3 files, as I personally know, never transmit enough. Because this is inherently a compressed audio file format.
The following are the audio bitrates of the Mp3 format including:
32 kbit/s – generally only acceptable for speech 96 kbit/s – commonly used for low quality speech or stream transmission128 or 160 kbit/s – mid-range bitrate quality192 kbit/s – bitrate for medium quality 256 kbit/s – a commonly used high quality bitrate 320 kbit/s – the highest level supported by the MP3 standard
If you want to listen to quality music, you should look for formats like flac, wav.
What is Video Bitrate?
Video bitrate is used to refer to the transfer rate of a file, video file. Video files here include popular formats such as: mp4, 3gp, avi, flv, mkv, mov, wmv, ….
Simply put, the higher the video bitrate, the better the video file quality. The video file image will be smoother, so will the sound.

Here is the current list of video bitrates:
16 kbit/s – video telephony quality (the minimum required for a picture that is “acceptable to subscribers” using various video compression systems)128–384 kbit/s – video quality business-oriented video conferencing using 400 kbit/s video compression – 240p750 kbit/s YouTube video – 360p1 Mbit/s YouTube video – 480p YouTube videoUp to 1.15 Mbit/s – VCD quality (using MPEG1 compression) 2.5 Mbit /s – YouTube video 720p(Typical) 3.5 Mbit/s – standard definition television quality (SDTV) (with bitrate reduced from MPEG-2 compression)3.8 Mbit/s – 720p YouTube video (in 60fps)4.5 Mbit/s – YouTube video 1080p (using H.264)6.8 Mbit/s – YouTube video 1080p (in 60 fps mode) Up to 9.8 Mbit/s – DVD (using MPEG2 compression)(Typical) ) 8 to 15 Mbit/s – High Definition Television (HDTV) quality (with bitrate reduced from MPEG-4 AVC compression) Approx. 19 Mbit/s – HDV 720p (using MPEG2 compression)<10 >Up to 24 Mbit/s – AVCHD (using MPEG4 AVC compression)<11>Approx. 25 Mbit/s – HDV 1080i (using MPEG compression 2)<10>Up to 29.4 Mbit/s – HD DVD Up to 40 Mbit/s – 1080p Blu-ray disc (using MPEG2, MPEG4 AVC or VC-1 compression)Up to 250 Mbit/s – DCP (using MPEG2 AVC or VC-1 compression) JPEG 2000)1.4 Gbit/s – 1080p uncompressed 4:4:4 10-bit at 24fps
