I say four because support for H265 is currently fairly limited, so practically speaking, there are only four to choose from when factoring in compatibility.

What is a Encoder in OBS?

What Kind of Encoders Are There?

There are two types of encoders:

• Software
• Hardware

You can think of a software encoderAn encoder is a tool that processes a computer screen, webcam, or camera and, in the case of broadcasting, transmits it to an ingest server. Alternatively, it will convert the processed image and audio data into a filetype for recording. More like an emulator – it fakes the process using clever programming. As a result, it is not quite as fast as hardware encoders, as it needs to be processed by a separate piece of unspecialized hardware (your CPU). With that said, what it lacks in speed, it makes up for with increased compatibility.

On the other hand, hardware encodingAn encoder is a tool that processes a computer screen, webcam, or camera and, in the case of broadcasting, transmits it to an ingest server. Alternatively, it will convert the processed image and audio data into a filetype for recording. More is accomplished using a purpose-built chip that does not need to be processed by the CPU before sending it on its way. This is because each step in the encodingAn encoder is a tool that processes a computer screen, webcam, or camera and, in the case of broadcasting, transmits it to an ingest server. Alternatively, it will convert the processed image and audio data into a filetype for recording. More process is hardcoded into a circuit, so the only limiting factors in this process are how well the encoderAn encoder is a tool that processes a computer screen, webcam, or camera and, in the case of broadcasting, transmits it to an ingest server.

All Encoders Are Equal With Enough Bitrate

The maximum bitrate you are capable of is calculated by multiplying your internet upload speed in Mbps by 1000.

The result is that neither process gets the processing time it needs to properly execute, resulting in very bizarre behavior.

1: The Best OBS Encoder: (New) Nvenc – GPU Encoding

The (New) Nvenc encoderThe Nvenc encoder is a hardware encoding chip onboard Nvidia graphics cards. While Nvenc performs slightly worse than X264 at lower bitrate values, it makes up for this by having a near-zero performance impact. This is possible because the encoding chip on the cards is dedicated silicon separate from the rendering cores. It is also for this reason that Nvenc is currently the leader in encoding options for broadcasting, at least until AV1 becomes capable of encoding a live broadcast.

Another reason you might not use this encoderAn encoder is a tool that processes a computer screen, webcam, or camera and, in the case of broadcasting, transmits it to an ingest server.

In which case, the alternative then is to use the X264 encoderX264 is an encoder that uses your CPU to encode media content.

This is because it is done at a software level, and almost all modern processors are capable of using it. However, because it runs as a software layer, it is far less efficient at processing the frame data. So it uses a lot of CPU computing resources to achieve the desired effect.

This can be especially pronounced when you are streaming a high CPU-demanding game, such as Anno 2077 or other simulation-based titles.

I’m not responsible for any damage to your PC if you attempt this and things go bad. Just make sure your power supply is higher than 850 watts before you try something like that.

As for where AV1 stands vs NVENCThe Nvenc encoder is a hardware encoding chip onboard Nvidia graphics cards. While Nvenc performs slightly worse than X264 at lower bitrate values, it makes up for this by having a near-zero performance impact.

It is also for this reason that Nvenc is currently the leader in encoding options for broadcasting, at least until AV1 becomes capable of encoding a live broadcast. More (New), that has yet to be determined. However, for all you AMD or Intel GPU users out there, this might be a game-changer for you.
