Why Use An Encoder?
• In this previous slide, we showed how to FB Live
without using a video encoder.

to-fblive
• But it does not always work well on all devices.
Sometimes you cannot share the entire desktop
screen. Therefore when you jump between
applications, the FB Live stops suddenly, disrupting
broadcast.
• Therefore a video encoder running on a separate
PC/notebook will help to FB Live seamlessly.

What video encoder to buy?
• You can go for the industry standard like Epiphan Video
Pearl 2 which will set you back around USD6XXX. The faculty
did not get back to me on that quotation.
• I am a lowly paid government civil servant, so I opted for a
cheaper version.
