Topic: Easiest way to make video recordings using iPhone

I'm wondering what the easiest way to make a video recording of me playing my digital piano and using Pianoteq.  I have Pianoteq on both my Lenovo laptop as well as my iPhone.  I tried just connecting the iPhone via a lightning cable to USB from the laptop - w/o success.

The easiest would be to do a regular recording with the camera app. The audio will be probably bad, but Pianoteq records everything you play as MIDI, no problem.

After the fact you would re-render the audio of what you played from the File->RecentlyPlayedOnTheKeyboard menu and save it as FLAC with File->ExportToAudioFile.

At that point you can download the video recording on the computer from the phone, and use a second program (I like ffmpeg) to replace the bad audio from the video file with the good audio made straight from Pianoteq. I use a command like

ffmpeg -i video.mp4 -i k1_shifted.flac -c:v copy -map 0:v:0 -map 1:a:0 new.mp4

you can find lots of information about that ffmeg on stackexchange or you can use another video editing program of your choice, replacing the audio should be easy with anything you decide fits your style. Note that the name of the audio has a "shifted" in the name since you will need to "shift" in time either the video or the audio to make them be in sync. I find that shifting audio is easier.
