hello, this is my second question. right after my previous question about synchronizing kinects from different PCs.

I am using 3 kinects per PC. Would this work too? So total 6 kinects to be synchronized.

thanks for your fast and kind answer.

    Hi @Park Danny Thank you for sharing additional information on your use cases. This is an interesting scenario as it involves a combination of devices which are connected to a single host PC and different PCs.

    The limitation here is that there could be only one master device which could take in all the recordings. If we were to follow the guidelines in the article, it implies that Azure Kinect DK devices connected to single host would have a master device of its own and other disconnected devices would have another master device. Obviously, this is not feasible, because if you declare/start a device as Master, it will not send out any data out to sync with other devices. I hope this makes sense.

    Try running 5 of the devices with the command k4arecorder.exe --external-sync sub -e -8 -r 5 -l 10 sub1.mkv and see if they can be synced with a single master which you would start with k4arecorder.exe --external-sync master -e -8 -r 5 -l 10 master.mkv

    Let me know if this helps.
