The common belief is that more pixels means a higher-quality picture for viewers. But this isn’t necessarily true, thanks to the video compression process.

Hardware Video Encoder Comparison: BoxCaster vs Teradek VidiU vs Digicast DMB-8800A

February 13, 2017

This post is an in-depth comparison of three hardware video encoders: the BoxCaster, Teradek VidiU, and Digicast. It's the main post in our series on video encoders.

Live video streaming is often best accomplished by way of a hardware encoder (see our post about why that is). The encoder is a physical device that connects to a video source and converts the audio and video signals into something that can be streamed to a media server. While many hardware encoders share similar features, chipsets, and form-factors, they're not all made the same and can produce different results given otherwise similar conditions.
