Why Transcoding is Important in Live Video Streaming

2 min read

Transcoding is one of the most crucial factors when you do live video streaming. For optimized delivery across multiple devices, video transcoding is very important.

What is Video Transcoding?

Transcoding is a process of converting video content to multiple bitrates and resolutions. During this process, the video gets converted to different resolutions, and this results in a smaller file/stream size.  

Why we need transcoding why it’s important?

There are two types of transcoding in video streaming.

  1. Live stream transcoding
  2. Video transcoding

Live Video Transcoding

When you are live streaming, if you are streaming at 1080p 60fps, then you should stream at 8 Mbps for the best quality.

If you are streaming live at 8 Mbps, then most of the computers with a good network can play the stream without any trouble, but mobile phones might face issues, and there is no point for us to play an 8 Mbps stream on a mobile phone.

Using Castr, your stream gets transcoded into multiple bitrates, which means the stream gets available in 720p, 480p, and 360p with the following bitrates.

Streaming Resolution Bitrate
1080P Copied From Source
720P 5 Mbps
480P 2.5 Mbps
360P 1 Mbps

Video Transcoding

When you record a video, you will be recording in the highest quality, a 1080P video of 10 minutes long might have a size of 7 to 8GB. When you upload the file to a Video Hosting solution, if they don’t have the option for transcoding, then the stream will be delivered to the users in the same size. This means any user who watches the video will be consuming 7 to 8GB of bandwidth.

Video transcoding is required for smoother playback, and you will be able to save bandwidth. Users will be able to get a much better experience of watching your video.

When you upload videos to Castr, Castr video hosting solution will transcode the uploaded file to multiple bitrates. Also, it will reduce the file size drastically without losing quality.
