![]() ![]() URa圜oder also has relatively low-cost units that accept SDI input ($248) and output HEVC $238). Passthrough is a useful feature for encoders in this class.Īs you see in the diagram, you can also display the video from a separate decoder box or on a computer or mobile device that can access the URL of the video encoder, both relatively common features. You can control the unit via a webpage on a computer or via App control, and the unit can broadcast to up to four services simultaneously, though you’ll need 4x the outbound bandwidth to do this. This provides a nice confidence monitoring function (yes, the unit is receiving video) and could be useful for some presentations or events. In the diagram below, you see that the unit has an HDMI loop through, so you can attach an HDMI monitor to watch the display. Here’s the URa圜oder Wired 1080P H.264 HDMI Video Encoder. As the name suggests, the unit accepts HDMI input at 1080p maximum. One unit that ticks all the right boxes (and provides a great diagram to assist our discussion) is the URa圜oder Wired 1080P H.264 HDMI Video Encoder, which is an Amazon Choice with a 4.5 star average with 100 ratings ($188). 1) URa圜oder Wired 1080P H.264 HDMI Video Encoder General Purpose Encodingįor general purpose streaming from a fixed location with power and internet, you can focus on cost and simplicity. With these questions in mind, let’s start exploring different encoder classes for different applications. ![]() On the other hand, if the talent and production team are in a closed space, encoders without noisy fans are definitely best. If you’re running the encoder in a closet, obviously you don’t care about this. If neither of these are available at your production location, you’ll need an encoder that can connect via cellular. Virtually all encoders have Wi-Fi capabilities, Ethernet, or both. Others also enable control via a smartphone, which may be more convenient if you don’t have a computer handy. Typically, you control these units by logging in to them from a browser that can access its IP address, which works well when you’re connected on the same LAN. Most encoders don’t have control interfaces that you can use to directly connect to a cloud-based service. To access these features, you’ll need a more professional (and expensive) encoder. Support for more exotic fare, like SRT support for low latency and/or HEVC support for low bandwidth streams, is less available - though rest easy, Wowza Streaming Engine supports both. All encoders should be able to connect to these services without issue. Some services are relatively generic with H.264 and RTMP the main flavors available. Here are the specifications for Wowza Streaming Engine. If high frame rate, HEVC, high dynamic range (HDR), and/or 4K/8K are currently required or in your future, you may need a more capable encoder.Īll transcoding and delivery services publish specifications that detail the protocols, container formats, codecs, and other information about the streams that they ingest. Virtually all encoders can produce fps 8-bit input with the H.264 codec. Also consider the number of connections, particularly in the context of a broadcast application or lecture capture, where the output signal will combine multiple sources like PowerPoint input from a laptop with a talking head video. SDI) as well as resolution and frame rate (1080p/4K, 30/60 fps). The major differentiators here are connection types (HDMI vs. Like most technical products, identifying the best encoder for a particular application starts with a number of questions. In contrast, encoders input your video, encode into a compressed format, and deliver it to the internet for transcoding. However, capture products almost always connect your video source to a computer, typically via USB, so you can input your video into a video mixing application. It’s easy to confuse the two because many encoders and capture devices may look similar and come from the same manufacturer. However, because encoding is a CPU-intensive process that can steal CPU cycles from these programs (and potentially degrade performance or stability), many producers eschew using an integrated encoder for a separate hardware encoder.īefore digging deeper, let’s distinguish encoders from capture devices. Most software-based video mixers, from OBS to the TriCaster, have integrated encoding capabilities, which are always an option. I’ll cover only the former category in this blog post, not the latter. What Is an Encoder and Why Is Hardware Better?Īn encoder is a device or program that inputs a video signal and outputs either a compressed stream for delivery and transcoding to a cloud service or a complete encoding ladder ready for delivery.
