re.: How to record video of MIDI visualizer and real piano player integrated into one ?

  1. There is a nice video of MIDI Visualizer playing back MIDI file

img-9gag-fun.9cache.com

at the later time, graphics files get integrated into piano roll and played as musical notes

HowTO?

  1. There are musical videos on YouTube, Facebook, made of MIDI Visualizer integrated with real piano player playing on the keyboard

  • MIDI Visualizer videos by Stephen Malinowski are highly sophisticated but piano roll is played horizontally vs. vertically ( rain mode) by Rodriguez, Brendan, Rousseau youtube.com/watch?v=mJZR91YggAw

  • Just tell me if placing large screen TV over the piano keyboard, playing MIDI file animation is the correct solution, as depicted in the above video

    Ever heard of "video editing" applications? Commented Jul 23, 2020 at 9:03

Not an expert, but definitely looks like a simple overlay of a synthesia video on top of a recording of him playing the song on a keyboard. So, say you want to record this in one go, you need to:

  1. load the midi file of the song you want to play in synthesia
  2. use screen recording software to record the computer screen while it's playing the song in synthesia
  3. at the same time play along with a midi keyboard and record this with a topview on your phone
  4. in video editing software, crop the keyboard video to show the keys and your hands only. (convert to black & white, if you REALLY want the same effect)
  5. in video editing software, overlay the synthesia video on top of the (cropped) keyboard video and use some kind of blend mode e.g. "multiply" this will give you the effect of the colours radiating on your hands and the keys

So no, there's no need to place a large tv over the keyboard. it definitely won't look the same.

  • Thank you for your excellent answer "in video editing software, overlay the synthesia video on top of the (cropped) keyboard video and use some kind of blend mode e.g. "multiply" this will give you the effect of the colours radiating on your hands and the keys Let me verify " use some kind of blend mode e.g. "multiply" this will give you the effect of the colours radiating on your hands and the keys since blending is flat 2D effect but what an be seen is 3D blend effect, since Brendan's finger and hands shade the illumination light

  • good hint "in video editing software, crop the keyboard video to show the keys and your hands only. (convert to black & white, if you REALLY want the same effect) -------------- hands play the keys in black & white mode

    @darius "Brendan's finger and hands shade the illumination light" I don't see that.

    @darius there's simply no need for such a service. If you have a midi keyboard, you can easily record whatever you're playing as midi signals.

    Well of course both can be completely seperated. You can load the midi file in synthesia and record it and then play on an analogue piano and record it. The 2 videos can be seperated fully.
