OBS Studio (Open Broadcaster Software Studio) allows live video recording and streaming.

Today, thanks to high-speed fiber connections and video websites like YouTube, Twitch, Vimeo, etc., sharing videos is within reach of millions of people. With this possibility of sharing and streaming videos, software needs to be able to record efficiently.

OBS Studio appears as an advanced solution for live video recording and streaming. Let's see the details of each of these two options.

Video recording :

You'll probably want to record your PC desktop, a specific application, or even a certain monitor region. With OBS Studio, you can do all this and more.
Once we've selected what we want to record, we can choose between the recording options, like video and audio format, recording quality, recording codec, and more.
After setting up all the options, we will only have to press the “ Start recording ” button for the video to be saved on the hard disk, together with our PC's events.

Live streaming :

If you are a gamer and want to stream on Twitch or a YouTuber who wants to make a live video there, you can do it with OBS Studio after setting up the proper parameters.
Just as with video recording, we can configure the codec, video and audio format, and streaming quality so that, if we have a slow Internet connection, we can set the OBS parameters to reduce the video and audio quality and to allow the most fluid streaming possible. We can also set a buffer to keep the audience from coming across the typical loading screen, which can be annoying.

The recording and streaming options are independent. This means we can record a video without streaming it and stream it without recording it. We also have the option of simultaneously recording and streaming.

In the video recording and streaming options, we can choose from different audio and video sources, so apart from the desktop and its windows, we can capture video and audio from a webcam or the sound of a USB microphone.

One of the strongest features of this software is that we have the chance to create scenes. These consist of elements like still images, desktop windows, and text. Thus, we can create a very special recording. For example, we can create a scene with a background of a video game cover, adding the video of our webcam on the right top, the video game we're playing on the center, and thanking the audience watching the video on the left top.

Another significant feature of this software is its ability to adapt it to our needs, thanks to its great number of options. This might mean an issue for less advanced users since they might feel overwhelmed by the number of available options.

The software is free and supports many, so it is ideal for medium/advanced users that want to stream and record live videos of their PC events.
