Thank you very much for your answer!
It looks that I did not find the way, because not possible.. That makes sense.. hahahaha
Are you 100% sure? I just want to catch the internal iMac audio instead the iPhone Microphone to record the video in Quicktime.
In my head, digitally, I still thinking it should be possible, but yeah, I am not experienced, so I could be totally wrong.
But is not possible to send from Logic audio to Speakers, + another to "something" (Soundflower, Blackhole etc) that sends to Quicktime?
Thank you very much for your help, I will think about it if i can not find the way, to get the CAM and follow step by step yes, but pff, my phone is really nice Camera, I just need the built in audio from iMac to go to Quicktime, instead the phone Microphone. In my head: Logic out to Speaker + Quicktime (Or supportive app that sends to Quicktime)
I thought Soundflower is not working in Catalina, just alternatives I found and I get already crazy with not much results more than get hyper confused.
By the way, I do the recordings with the iPhone connected by Cable, if not not possible to record from Quicktime, and there is not latency as far as I see.
It is the phone recording everything, even Audio, so there is not lag. Then, if possible to do what I a trying to do, maybe I could find that lag, but anyway, if is the same video, and song, adjusting will be not that hard. If they are 2 separate records, yes, thats crazy hahah
I hope I trigger some new idea from you guys. Thank you for your help!
