The F239+ is a broadcast video encoder that takes one or two HDMI or component video sources up to 1920×1080 Full HD resolution and can encode two independent video streams of similar or varying bitrates for broadcast or recording. With its powerful dual H.264 High-Profile codecs, it allows live Full HD Video to be simultaneously broadcast and recorded at higher quality for VoD playback, Multicasting and support for popular streaming services providers as well as Facebook Live allows live video from the F239+ to be broadcast to a virtually unlimited number of viewers.

Encode and Stream Content Simultaneously

Powerful dual H.264 codecs and Gigabit Ethernet ports allow the F239+ to simultaneously live broadcast two independent video streams at Full HD quality in Duet mode, allowing for instance, multiple angles live streaming.

With two independent codecs, bitrates can be adjusted separately for each output to account for network bandwidth or higher quality VoD content.

Finally, Splitter mode allows a single stream to be broadcast at different bitrates or to support different protocols and service providers.
