Mirillis Action! streaming configuration

At the very beginning, it’s important to adjust streaming settings to Internet connection upload speed. Go to LIVE streaming tab. Set video size, framerate, and bitrate for your broadcast. In case of problems, you should reduce video size and/or framerate/bitrate and try again.

Please note that Live streaming in HD resolution is recommended for PCs with Intel Quick Sync Video, AMD APP or NVIDIA NVENC acceleration for video encoding.

Internet connection might be one of the biggest obstacles while streaming. Streaming transmits a considerable amount of data, that is why we need high Internet speed connection. Most of us don’t check the upload speed while signing the agreement with their Internet service provider. It happens that Internet speed quality is 10 to 1. Basically, it means that if your download speed equals 50 Mb/s, the upload speed is only 5 Mb/s. To share the best video quality, recommends 4 Mb/s as upload speed. If your upload bandwidth is too low, let’s say your connections ensures 1 Mb of data transfer speed, you can be almost sure that instead of smooth video quality your recipients get a beautiful slideshow. In general, the minimum upload speed for classic 3D games estimates around 2 Mb, however, when it comes to dynamic shooter games 2 Mb might appear not enough. Some Internet service providers offer symmetrical Internet connection, which means that download and upload speed are close to identical. If you are curious how fast is your connection speed go to

Camera and microphone

If you want to give your streams a personal touch add a webcam to your recordings. Enable webcam, click on webcam settings button right next to it and set the size and the position of your webcam. If you want to apply a green screen effect not to show your home or office background, select Use Chroma key option. To make this effect work perfectly, don’t forget to place some curtain with uniform color behind your back.

You can record your webcam in three ways: all the time, on a button (you start/stop recording when you press F4 button) or you may record your webcam only if you press and hold F4 button. Please note that if you are a laptop user, default Action! hotkeys might require pressing additionally function button (Fn).

If you want to attach voice commentary, you will need to set up and configure your microphone in almost the same way as a webcam.

How to add logo to my streams

To make your streams look even more professional, add your own watermark. To apply your own logo, go to either game or screen recording mode and click Overlay graphics tab and upload your watermark. Next, choose the position of the overlay graphic and done.

We’ve implemented a new feature that supports Streamlabs and other similar overlay widgets available on the Internet. They will make your stream look professional. Not only can you create those overlays for your viewers, but you can also make them visible on your screen while you’re streaming. So how’s it done? First off, you need to log into for example via your YouTube or Twitch account.

Then go to any overlay category you are interested in. In the example shown on the screen, we’ve clicked on “chat box” widget section. The chat box is already pre-customized, so if you don’t want to delve into it too much, simply press copy near the blurred link and then paste it into Action! in the designated area. It is located in the bottom section of either game recording mode or screen recording mode.
