Valve is currently testing another new feature for Steam. This is officially called Recordings (in English Game Recording) and is available to everyone in the beta version the Steam client itself. This means that it shouldn't be long before the feature is officially launched.
Recordings appeal to four key functions – recording, playback, clips and sharing.
In terms of recording options, the function is not much different from what we know, for example, within the Shadowplay service from Nvidia or perhaps the streaming software OBS. Recordings support two modes. On request classically, recording starts and ends after performing a keyboard shortcut. Background however, it will record your playing continuously and backwards for the time you set (up to 9999 minutes). This means that once you've done the shortcut, Steam can upload the last few minutes for you if you do something special.
And specifically in several possible qualities from 1.5 Mbit to 24 Mbit (unfortunately, even a higher number cannot be set manually, at least not yet). As well as Recordings support GPU acceleration – so the feature shouldn't affect your gaming performance – and it can even record your microphone. You can also choose whether should the recordings record only the given game or the entire systemor only selected programs (unfortunately without division into individual tracks).
In addition, directly in Steam and during gameplay, you can open a separate Recordings window, where you can directly view recorded clips in real time, but also the timelinehere you are to give marks or from video cut the clip. The latter is then not only possible export as mp4 filebut also to someone send directly to Steam chathave it sent to another device (like Steam Deck), to mobile or even to the mailbox and then perhaps paste it into Discord. Some of these functions may not work if the clip is too long. But they should always be available for a clip with a maximum length of 60 seconds.
