record stage in HAP?

[artoo]

hi guys, 

is there a way to record a stage in hap alpha codec?

i need to keep the alpa channel of the stage so i can do it in ProRes 4.4.4. but it's a bit heavy for what i am doing... (it's a recorder/looper patch that capture movies from a webcam with alpha channel and play them on 8 layers so the ProRes 4.4.4 codec is not the best one to keep interactivity performances...)

i'm on MacM1 running Monterey with isadora 3.2.6 

thanks a lot.

artoo.
