I don't know exactly how he recorded this, but there are many options. If you're using Windows 10, there is a Game DVR feature pre-installed. You click Windows key + G and it opens the panel. The shortcut to record is Win+alt+R, but you need to allow the recording before if it's the first time you do it. If you don't have the Game DVR, you can download a screen recorder like OBS. Another option is to buy an external video capturer. Now, if you want to look at a replay from Velocidrone (without having to record any video) there is a feature after you finish a race in which you can watch the replay. I hope this helps.

@@Jimmyfpv_ Thank you for your detailed answer!) I tried OBS, but the system didn't pull. I'll record it on my camera. Please tell me how to view the record after the flight in Velocidrone? I didn't find it.
