In telecommunications, average bitrate (ABR) refers to the average amount of data transferred per unit of time, usually measured per second, commonly for digital music or video. An MP3 file, for example, that has an average bit rate of 128 kbit/s transfers, on average, 128,000 bits every second. It can have higher bitrate and lower bitrate ...
However, video on an XVCD is typically encoded at a variable bit rate (VBR), so complex scenes can use a much higher data rate for a short time, while simpler scenes will use lower data rates. Some XVCDs use lower bitrates in order to fit longer videos onto the disc, while others use higher bitrates to improve quality.
The advantages of VBR are that it produces a better quality-to-space ratio compared to a CBR file of the same data. The bits available are used more flexibly to encode the sound or video data more accurately, with fewer bits used in less demanding passages and more bits used in difficult-to-encode passages.

The festival started last year, bringing together both local songwriters and artists like the Watson Twins, to share their music with the city at Wesselman Woods. This year, music is set to start ...
H.264 can often perform radically better than MPEG-2 video—typically obtaining the same quality at half of the bit rate or less, especially on high bit rate and high resolution video content. [50] Like other ISO/IEC MPEG video standards, H.264/AVC has a reference software implementation that can be freely downloaded. [51]
Higher Ground, the South Burlington-based music venue that books off-site shows throughout the Northeast, began powering its long-running Concerts on the Green series at the Shelburne Museum this ...
Each year, Freep Film Festival presents a number of free educational events that are designed to bolster the local filmmaking community. Here's a rundown of what's in store in 2024.
Possible bitrate and latency combinations compared with other audio formats. Opus supports constant and variable bitrate encoding from 6 kbit/s to 510 kbit/s (or up to 256 kbit/s per channel for multi-channel tracks), frame sizes from 2.5 ms to 60 ms, and five sampling rates from 8 kHz (with 4 kHz bandwidth) to 48 kHz (with 20 kHz bandwidth, the human hearing range).
