Best Bitrate Converter to Change Video Audio Bitrate

Bitrate is the speed which a video or audio is transmitted, measured in bits per seconds. Typically:
– Video played on smart phones has a bit rate measured in kilobits per second (kbps).
– High-quality video found on the web has a bit rate around two megabits per second (mbps).
– Standard-definition DVD video is usually about 6 mbps.
– HD Blu-ray video is about 20 mbps.

How bitrate influences video/audio quality?

The higher the bit rate of a video, the more data gets transferred at a time. Therefore, higher bitrate usually means high quality video. However, video with very high bit rate will also strain the capacity of slower Internet connections and many mobile devices. This can result in buffering and interrupted streaming. Therefore, to save more space for your device and also achieve a smooth video streaming or transferring process, you will need a bitrate converter program to change the bitrate of different video and audio from high to low.
