If you are using an Ipad to make music, edit videos or just curious of visuals this video
is a proof of concept that an m1 ipadpro can record 4 videos at once. I also added a video
in the description for 4 output videos from VS Visual Synthesizer to show the concept
even further. I did try 4 VS output videos and a screen recording but the (FPS) frame rate
went down to 12fps and it was more glitch art than useable.
You need:
A recent Ipad for two videos at once (it can be done on older models with some tweaks)
AUM or Audiobus to host
Visual Synthesizer auv3
Lumafusion or video editor that accepts multiple video fromats
any auv3 synth app
a sequnecer or midi controller to trigger VS
