So, I'm having difficulties with clearing some timed levels in a platformer. Even when I feel like I've pressed every button perfectly, I can still barely clear it; and some levels are still beyond me. I've tried watching regular videos on YouTube, but they seem pretty much like the same thing that I do - except they make it and I don't. I've tried looking at speedruns, but what happens there is so mindbending that I cannot even begin comprehending it.
So I was thinking about asking for help on the internet. Probably on some speedrunning forum where this would be on topic, but maybe here. But to ask for help in a meaningful way would also involve showing them what I'm already doing - and that means recording a video. Even more, since some things can happen so fast that it's unclear what is being done, I would like my button presses to also be visible in the video.
I know of plenty of ways to record a session. Fraps, Microsft Game Bar, the Radeon software - just to name a few. But they all only record what is visible on the screen. I would also like my button presses to be visible there. I'm using a USB gamepad (controller?), but I can also play with the keyboard, if that makes things easier. I haven't seen any videos like that so I'm guessing this is an uncommon thing to do. But does anyone know of a way?
