Multi-encoding and channel as a source

Unify lets you easily do multi-encoding so you can record and stream the same content at different encoding settings. This is useful when you want to:

• Record a video at a high bitrate and frame size and live stream the same content at lower encoding settings.

• Record the channel while also sending two (or more) streams of that channel using different encoding settings for CDNs that don't use adaptive bitrates.

For example, take a scenario where you want to record a video at 1080p and 8 Mbps, while simultaneously live stream the same video online 720p and 1 Mbps. You can create your custom layouts and do all your switching in one channel (i.e. Channel 1) and then configure Channel 2 to use Channel 1 as a source. That way, both channel's have the identical program. All you need to do now is configure each channel for the encoding settings you want.

Follow these steps:

• Log in to the Admin panel as admin, see Connect to the Admin panel.

• Create Channel 1 with your video and audio inputs. Add all your live switching layouts.

• Set the **encoding **and **streaming **settings for channel 1.

• Create Channel 2 for your recording with just one layout and add Channel 1 as the video source. Stretch it to fill the full screen.

• For Channel 2's audio source, choose Channel 1 if not already selected by default.

• Set **encoding **and **streaming **settings for channel 2.

Using this process, you can again use the same video you’re recording on Channel 2, and stream it at a different bitrate and frame size.
