Do you use Android or IOS? If you use Android, you can capture the video with the Android SDK tools. http://adbshell.com/commands/adb-shell-screenrecord The command you have to execute from the folder where you have the Android tools, they are usually in: .. \ android-sdk \ platform-tools adb shell screenrecord /sdcard/video.mp4 The only thing that does not capture is the sound, and has a limit of 3 minutes. There are also many applications on Android to capture and edit video from the phone: https://play.google.com/store/apps/details?id=com.duapps.recorder If you use IOS, you can capture the screen with QuickTime Once the video has been captured, you can edit it with the free programs: Windows Movie Maker for PC iMovie for MAC
As I know, if you have Windows 10, you can press Win+G to open its built-in digital video recorder, Game DVR. There are also many other people saying that the Game Bar and Xbox App are useful as well. But as for myself, I used to use Joyoshare Screen Recorder to capture WOW gameplay on my computer. To be candid, it is far better than any built-in screen recorder on my Windows... It helps me capture game videos easily and quickly. By the way, it has no time limit. I would like to recommend it to you and hope that you can find it useful as well.
Better to use OBS Studio works well with video, sound recordsing and specific window capture and specific area of the screen https://obsproject.com/ After video recording you can add extra effect using HitFilm Express Editor https://fxhome.com/hitfilm-express
