![]() The current firmware doesn’t seem to support B-frame encoding (available in Main and High profiles of AVC/H.264) very well, at least for typical RTMP pushes to streaming media servers. Changes are near-instantaneous without laborious reboots of the hardware. The silver lining, though, is that the HELO’s web interface is incredibly fast. ![]() As such, you need to make sure all your configuration data is in place before you start to stream, unless you have a laptop on hand to connect to the same network as the HELO. ![]() The HELO requires all configuration to be done within a web browser user interface there is no display and/or input control on the unit itself. The drawbacks of the HELO are few, but notable. This application will report the IP of the HELO so you can configure the device in a web browser. If you don’t have a Bonjour-enabled device or browser, you’ll need to use the AJA eMini-Setup application on a laptop or desktop computer to discover the HELO. If you have Safari, you can enable Bonjour discovery and quickly navigate to the web configuration page for the HELO. #BEST FREE VIDEO ENCODERS 2017 MAC#If you’re using a Mac or Bonjour-enabled device, the HELO’s address will be announced and available over Bonjour. While the HELO doesn’t have a form factor designed for portability or mounting as nicely onto a camera as the Teradek Cube 655, you can purchase separate power adapters to run the HELO from popular battery types.ĭiscoverability of the HELO on the network is relatively simple. You can also store multiple presets and profiles for the encoder, making it faster to change from one configuration to another. All of the input and output jacks for video, audio, network, and power are on the back side of the chassis, while more user-friendly push controls to enable recording and streaming and USB/ SD card recording media are on the front side. Its rack-mountable design makes it a compact addition to an existing footprint for a more permanent A/V rack. While its form factor was the second-largest in this roundup, the HELO is not designed to be camera-mounted. This encoder has a very simple and compact design. This much-anticipated entry to the H.264 encoder arena by AJA had some initial shipping delays, but was finally released in February 2017. Here’s a brief overview of each encoder, from least expensive to most expensive. Retail cost under USD$2,000, before applicable taxes and shipping costs.The ContendersĪmong the wide variety of encoders available in the testing period for this evaluation, I picked one encoder from four different vendors, each meeting the following minimum criteria: There are certainly encoders that are much more expensive, but most of my clients need portability and lower costs to add livestreaming to their existing pipelines. ![]() As we have entered the dawn of HEVC/H.265 technology-with very few economically priced encoders on the market-I thought now was a great time to compare the current stock of H.264 encoders that are available for under $2,000. My typical pipeline uses a first-generation Teradek Cube 255, which has held up very well and served my requirements over the past 5 years. I could not identify a single “winner” across all categories, but I could get repeatable results that you can use in your own research and comparisons for these and other encoders on the market. My goal for this article was to find the best encoder on the market for a wide range of live-streaming content, from relatively minor movement such as talking heads to fast-paced sports. I need an H.264 that will get the best possible quality over a limited outbound pipe of 1–3Mbps sustained bandwidth. The single biggest factor for my workflow is the available bandwidth on site at the event venue. For the last decade, I’ve used a variety of H.264 encoders for livestreaming events, typically conference events that involve one or more presenters and one or more computer screen inputs.
