I use a Canon EOS M-200 camera. It does reasonable quality recordings except very low light. I normally prefer to make recordings during the day. The camera has an onscreen playback. There is a beginning & end trim button so I can trim the video (leaving a few seconds slack on both ends) before exporting the video to a phone or computer for uploading online.
During the recording I'd place the camera on a tripod. The camera has optical zoom so zooming in doesn't degrade quality. I'd try to avoid extreme wide-angle or tele-photo to give a natural perspective. If I'm recording with a phone, I'd avoid zooming in. Older model phones usually have digital zoom which is basically cropping the video and degrading the quality. I prefer putting the camera on the left or right side of the piano /keyboard and shoot at about 45 degrees showing both hands playing.

At home there is a cabinet in front of the keyboard. I'd put the tripd on it and shoot down at a high angle for a bird's-eye view.

The least preferred shooting angle is from the left or right side of the piano straight down like the piano pokes into your face. I've seen many people shoot this way.

My 2 tripods for many years both have the brand name Manfrotto. These are made in Italy or China. It's a high-end brand that is very sturdy.
From the beginning I realized that the sound always have some background noise. I'd import the audio portion into a sound program like Audacity and remove the background noise later. Recombine the audio with the video in a movie editor after audio noise is reduced.
My latest recording is the intro of "Harmonious Blacksmith" by Handel. It's a piece I worked on before the Christmas break and recorded a few days ago.
