What is an encoder?
Encoders are devices that convert video files from one format to another. They can be either hardware or software-based. Encoders are essential for converting the RAW video files from your camera to streamable digital files.
Your encoder takes the necessary format and converts it into codecs through a compression/decompression process. The standard streaming protocol for internet sources is H.264.
We also recommended the video compression format for HD streaming. The H.264 protocol can create what’s called “lossless compression.” For audio-only streaming, there are two popular choices: MP3 (MPEG Audio Layer III) and AAC (Advanced Audio Coding).
There are two important protocols for broadcasting to keep in mind: RTMP and HLS streaming protocol. RTMP transmits the files from the encoder to the video hosting platform, and HLS transmits it from the video hosting platform to your audience. Since the RTMP protocol is so widely used, you’ll want to look into an RTMP encoder.
Now that you have a better understanding of the purpose of an encoder and how it works, let’s take a closer look at the two different types of encoders: hardware and software.
Software encoders are programs that run on your laptop, desktop computer, or another computing device.
There are several perks to using a software encoder. They are typically very easy to set up, and you can tweak or change most aspects of the codecs to get the bitrate and video quality you desire. You can easily update encoding software when a new version or upgrade is available.
Software encoders are generally appealing to beginner broadcasters because of their low cost and customization features. In fact, one popular open-source software encoders–OBS Studio–is free. Many Dacast broadcasters use OBS Studio since Dacast has partnered with OBS to create a custom encoding platform.
However, software encoders lack the overall speed that hardware encoders offer. This is because a computer runs multiple programs at the same time, and therefore can’t devote all of its resources to encoding.
Hardware encoders are dedicated processors that use a designed algorithm to encode video and data into streamable content. These encoders come in both smaller, portable boxes and larger permanent fixtures.
Given their higher price-point, mainly professional broadcasters tend to use hardware encoders. They are specialized specifically for encoding, which gives them an advantage over software encoders.
That said, the video quality of hardware encoders is usually pretty fixed. In other words, there’s not a lot of room to adjust video quality with hardware encoders. Given that hardware, encoders take time to design, build, and manufacture, they are sometimes equipped with older codecs. This makes hardware encoders very rigid, compared to flexible encoding software.
The higher price-point and lower latency that comes with hardware encoders set them apart from their software counterparts. You won’t find any free hardware encoders. You may find some for as low as $100, but for the most part, they reach towards the thousands.

Best Live Streaming Encoders for Different Broadcasters
If you’re oscillating between software and hardware encoders for live video streams, these suggestions might make your decision a bit easier.
Here are some suggestions based on encoders that work best for different types of broadcasts.
- Beginning Streamers: OBS Studio is free and allows you to familiarize yourself with the live streaming process. It offers a decent amount of features. Thousands of broadcasters, from beginners to experts, use this software.
- Live sporting events: Since these events take place in either a gym or a field, less equipment is ideal. You won’t need to take up much space with just your computer and camera. As mentioned above, Wirecast, in particular, has some great sports-related features.
- Live streaming from home: If you’re a broadcaster who occasionally wants to stream live video to viewers from home or in more casual settings, you’ll likely prefer something simple and free, like OBS Studio.
- Production Companies: When you are live streaming professionally, you likely need high-quality, crisp video streams for your viewers. In that case, live streaming hardware encoders are the best option for you. They are built specifically for live stream encoding and can transmit for days with minimal issues. That said, it requires a bit of a steeper budget and technical know-how to use a hardware encoder effectively.
Please keep in mind that your final decision should be based on the specific features you need to reach your live streaming goals.
Questions to Ask When Comparing Software and Hardware Live Streaming Encoders
Here are a few key questions to ask yourself when considering whether a software or hardware encoder will work best for your live streaming needs.
Will I use a professional streaming service?
In rare cases, a platform may have its own encoder. However, for the most part, you’ll find format-based encoder recommendations from your chosen OVP.
Will I need a portable encoder for live streaming on the go?
Different events call for specific encoder requirements. Software encoders are typically preferable for streaming on the go since they only require your laptop and are easy to set up.
For hardware encoders, it’s typical that broadcasters want the ability to transfer them easily between venues. The long-range of TeraDek’s Beam encoder, for example, will give you added mobility.
If you don’t need portability, however, there are fixed encoders that you can set up and keep in your recording space. Some of the hardware encoders are pretty heavy, weighing upwards of 20 pounds. If you feel that a heavy-duty encoder is best suited for an event, you can bring it to the venue and set it up once.
Which features will I need for my video content?
Knowing how you want your final video project to look when it is done, can play an important part in choosing the right encoder. Software and hardware encoders for live video streams differ in the features that they provide. Likewise, each company offers different services and advantages.
Closed captioning and ads, to name only a couple, are key features to consider. With the Wirecast encoder, ads are done by broadcasters using pre-recorded content. These pre-recorded ads are then inserted manually during the live feed.
What functions do I need the encoder to have?
Which features and functions you need will be one of your deciding factors for which encoder to choose.
Software encoders can come with a lot of functions useful for producing high-quality content. The right software encoder can handle multi-camera switching, title insertion, and playback on a disc-based file.
Hardware encoders, on the other hand, can be used for any multiple-camera producing content you might want to create. For context, most live broadcasts nowadays involve at least two cameras recording live content.
Now you know what an encoder is and why you might choose hardware over a software live stream encoder (or vice versa).
To recap, hardware encoders are more reliable, as they are built with the sole purpose of encoding and transmitting.
Software encoders usually run well, but their speed can depend on the computing device on which they’re installed.
Envisioning your end project is key in determining what features you need from the encoder. Ultimately, you should choose one that has the features that you need to reach your goals and is compatible with your broadcasting setup.
The most important thing is that you find an encoder that works for you and is within your budget.
