HD Live Streaming

What is Cloud Transcoding?

This post talks about using the process of cloud transcoding to ensure smooth viewer playback for your HD live streams. It's part of our series on HD live streaming.

Cloud Transcoding: The act of duplicating video into all of the various resolutions needed for smooth playback in the cloud.

Example: BoxCast uses cloud transcoding to break live video into five resolutions: 1080p, 720p, 480p, 360p, 240p to ensure smooth viewer playback.

How to Ensure Smooth Viewer Playback

In order for viewers to have a smooth playback experience across different devices with different capabilities in varying network conditions, you should provide several quality levels through adaptive bitrate streaming. In order to provide adaptive playback for your viewers, they have to provide multiple levels of video.

One option is to encode and stream each of these levels from your on-premise encoder. This utilizes a lot of processing power and network bandwidth.

Another option is to send one high-quality stream from an on-premise encoder like the BoxCaster Pro, and transcode to multiple quality levels in your streaming service.

 

Cloud Transcoding

Many streaming services (including free, advertising-based options like Facebook and YouTube) transcode in the cloud; the BoxCast Platform was one of the first to do so.  I highly recommend you transcode in the cloud to conserve encoding power and network utilization while maintaining smooth playback for viewers.
