    This is Why Your Live Stream Lags: Intro to Live Streaming Latency

    January 22, 2021

    It happens about once a week: Someone starts their very first stream with a camera pointed at themselves. While watching it on their computer or tablet, they’re surprised to discover they’re seeing themselves from about 30 seconds ago, and they call us to ask why their stream is so delayed.

    HDMI vs. SDI Video Connections: What's the Difference?

    May 04, 2019

    When streaming events live, there are several ways to output video and audio from a video source to a streaming device. Two of the most common are HDMI (High Definition Multimedia Interface) and SDI (Serial Digital Interface). This post sets out to explain the differences between the two.

    What's the Difference in SDI Signals (3G, 6G, 12G, Quad Link, etc)?

    March 21, 2019

    This post is a video explanation of the differences in SDI signals like 3G-SDI, 6G-SDI, 12G-SDI, and Quad Link SDI and talks about what they are used to accomplish. It's part of our series on video encoders

    Today we'll be talking about the different types of SDI signals. So, when I started in video production I thought that there was just one type of SDI signal. Boy you have no idea how excited I was when I found out it wasn't just that simple. I guess nothing's really ever simple is it?

    Hardware vs. Software Encoders: Why Hardware Encoders Are Better for Live Streaming

    February 21, 2019

    This post addresses the benefits of using a hardware encoder vs. a software encoder in your live video streaming setup. It's part of our series on video encoders.


    Encoding is the process of compressing large video files for easier uploading to the internet. Broadcasters who use video cameras in their live streaming setup need either a hardware or software encoder for the job.

    Encoding, Decoding, and Transcoding: How Your Live Stream Reaches Your Viewers

    January 29, 2019

    This post covers encoding, decoding, and transcoding, the processes behind sending live streams efficiently across the internet to your viewers. It's part of our series on video encoders.

    In its raw form, high-quality video is too bulky for broadcasters to upload and viewers to download. Encoding, decoding, and transcoding are three core processes that underlie the speedy transfer of video files to a playable format for your viewers around the world.

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

    October 25, 2018

    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.

    HEVC (H.265) vs. AVC (H.264): What’s the Difference?

    September 20, 2018

    We’ve all been there: watching an online video, movie, or sporting event when suddenly, the screen freezes up, or the quality isn't what it previously was. No matter what you’re watching, this abrupt loss of quality is incredibly frustrating.

    Recent technology known as H.265 (also called HEVC, or High Efficiency Video Coding) has emerged to combat this issue. In this post, we compare H.265 to its predecessor, H.264, and explore what H.265 means for your live broadcasts.

    HEVC (H.265): Impact on Live Streaming

    July 23, 2018

    It wasn’t long ago that the discussion of 4K capture and delivery seemed like an elusive hypothetical. Debates abounded regarding the need for 4K versus its high cost and potentially slow rate of consumer adoption.

    Five years ago, you’d have to take out a second mortgage to get your hands on a 4K camera. Today, your iPhone is a 4K camera. The change has been dramatic. 4K is no longer a topic of debate — the industry has clearly arrived.
