What is the Video Quality
Uploaded Videos are encoded in multiple bit-rates using QVBR (Quality-Defined Variable Bit Rate).
The largest video quality is dependant on the original video that is uploaded.
QVBR address the shortcomings of traditional Constant Bitrate (CBR) and Variable Bitrate (VBR) rate control modes. QVBR analyzes every macroblock, frame, and scene in the video source, and automatically allocates bits to address information differences: higher bitrate use during complex video segments, and lower bitrate use during less complex video segments.
Essentially this means that you are provided an enhanced version of variable bitrate control that provides the most efficient use of bits and scale video to maintain consistent video quality.
In laymen's terms, you will get the highest quality with the lowest storage requirement.
Viewing - Video Quality Rate Control
The default playback quality uses Auto. This means that the quality will adapt in real-time for the viewer and consider their network, device and other factors.
- From the Video Play, viewers can select Settings >Video Quality Rate Control
- This allows them to select to watch the stream from the list of video qualities available.
Troubleshoot Playback Quality
- If a viewer is experiencing buffer, be sure to select auto on the video player settings
- This will ensure that the live or on-demand stream adapts automatically to your device and network.
Advantages of QVBR
- Save costs: Lower storage costs and network streaming costs, from 10-50% depending on video content
- When streaming with QVBR, if a lower bit rate is sufficient for the same video quality, it will adapt for the viewer.
- Improve video quality (VQ) consistency: Maintain uniformity across all your content, and use a higher peak bitrate only for complex scenes
- Support the AVC and HEVC codec for even greater compression efficiency
- Remove restrictions with Constant Bit Rate
