What is Transcoding and How Does It Work? Why is It Important for Streaming?

Ever wondered how the same video can play smoothly on a high-end desktop and a slow mobile connection? That’s where transcoding comes in.

Transcoding is converting a video from one format, resolution, or bitrate into others, so it fits varying devices and network speeds. It includes:

Transrating: changing the bitrate (e.g. from 16 Mbps → 5 Mbps → 1.5 Mbps)

Transsizing: changing the resolution (e.g. from 1080p → 720p → 480p)

These renditions power adaptive streaming, so viewers get the best possible quality without buffering.

Without transcoding, many users would suffer from buffering, or wouldn’t even be able to view the stream on their devices.

👉 In short: if you want your stream to reach everyone, transcoding is essential.
